Equip irrigation in the greenhouse with your own hands. Drip irrigation method in greenhouses. Drip irrigation system

Providing water to plants and plantings is one of the concerns of homeowners. Some water vegetable beds, some water flower beds and lawns, and some need to provide water for their garden. In any case, the procedure takes quite a lot of time. But that’s not all: with the usual method, a crust forms on the surface, which prevents plants from developing, so you have to loosen the soil. All these problems can be solved by drip watering the plants. You can buy ready-made kits, order turnkey development and installation, or you can do everything yourself. This article will discuss how to make drip irrigation yourself.

Operating principle and varieties

This technology was tested several decades ago. Its results were so impressive that the system became widespread. The basic idea is that water is supplied to the roots of the plants. There are two ways:

poured onto the surface near the stem;
fed underground into the root formation zone.

The first method is easier to install, the second is more expensive: you need a special hose or drip tape for underground installation, and a decent amount of excavation work. For temperate climates there is not much difference - both methods work well. But in regions with very hot summers, underground installation has shown itself to be better: less water evaporates and more of it gets to the plants.

There are gravity systems - they require a water tank installed at a height of at least 1.5 meters, there are systems with stable pressure. They have a pump and a control group - pressure gauges and valves that create the required force. There is completely. In the very simple version This is a valve with a timer that opens the water supply for a specified period of time. More complex systems can separately monitor the flow of each water supply line by testing soil moisture and determining the weather. These systems operate under the guidance of processors; operating modes can be set from the control panel or computer.

Pros and cons

Drip irrigation has many advantages and all of them are significant:

Labor intensity is significantly reduced. The system can be fully automated, but even in the simplest version, irrigation requires literally a few minutes of your attention.
Reduced water consumption. This happens due to the fact that moisture is supplied only to the roots, other zones are excluded.
Eliminates the need for frequent loosening. With a dosed supply of water to a small area, a crust does not form on the soil; accordingly, it does not need to be broken.
Plants develop better and productivity increases. Due to the fact that water is supplied to one zone, the root system develops in this place. It has a larger number of fine roots, becomes more lumpy, and absorbs moisture faster. All this contributes to rapid growth and more abundant fruiting.
It is possible to organize root feeding. Moreover, fertilizer consumption due to point supply is also minimal.

The economic efficiency of drip irrigation systems has been proven many times, even on an industrial scale. In private greenhouses and vegetable gardens, the effect will be no less significant: the cost of creating the system can be reduced to a small amount, but all the advantages will remain.

There are also disadvantages, but there are very few of them:

For normal operation water filtration required, and these are additional costs. The system can function without filters, but then it is necessary to consider a purge/rinse system to remove blockages.
Drippers become clogged over time and require cleaning or replacement.
If thin-walled tapes are used, they may be damaged by birds, insects or rodents. Places of unplanned water consumption arise.
The device requires an investment of time and money.
Periodic maintenance required— blow out the pipes or clean the droppers, check the fastening of the hoses, change the filters.

As you can see, the list of shortcomings is quite long, but all of them are not very serious. This is a really useful thing in the garden, garden, flower bed or.

Components and layout options

Drip irrigation systems can be organized using any water source. A well, borehole, river, lake, centralized water supply, even rainwater in tanks will do. The main thing is that there is enough water.

A main pipeline is connected to the source, which supplies water to the irrigation site. Then it goes along one side of the irrigated area and is muffled at the end.

Opposite the beds, tees are inserted into the pipeline, to the side outlet of which drip hoses (pipes) or tapes are attached. They have special droppers through which water is supplied to the plants.

It is advisable to install a filter or filter system between the outlet of the source and the first branch onto the bed. They are not needed if the system is powered from the home water supply. If you pump water from a lake, river, rainwater tank, filters are required: there can be a lot of contaminants and the system will clog too often. The types of filters and their number are determined depending on the condition of the water.

Drip hoses

Hoses for drip irrigation are sold in coils from 50 to 1000 meters. They already have built-in water flow points: labyrinths through which water flows before entering the outlet. These oozing hoses provide the same amount of water throughout the entire line, regardless of the terrain. Due to this labyrinth, the flow rate at any irrigation point is almost the same.

They differ in the following characteristics:

- Tube stiffness. Drip hoses can be hard or soft. The soft ones are called tapes, the hard ones are called hoses. Hard ones can be used for up to 10 seasons, soft ones - up to 3-4. Tapes are:
  - Thin-walled - with a wall thickness of 0.1-0.3 mm. They are laid only on the surface, their service life is 1 season.
  - Thick-walled tapes have a wall of 0.31-0.81 mm, service life - up to 3-4 seasons, available for both above-ground and underground installation.

Watering can be organized using tapes or hoses

The maximum length of the irrigation line is determined so that the unevenness of the water output at the beginning and end of the line does not exceed 10-15%. For hoses it can be 1500 meters, for tapes - 600 meters. For private use, such values are not in demand, but it is useful to know)).

Droppers

Sometimes it is more convenient to use droppers rather than tapes. These are separate devices that are inserted into a hole in the hose and through which water is supplied to the root of the plant. They can be installed in arbitrary increments - put several pieces in one place, and then several in another. This is convenient when organizing drip irrigation of shrubs or trees.

There are two types - with standardized (constant) and controlled water release. The body is usually plastic; on one side there is a fitting, which is inserted with force into the hole made in the hose (sometimes rubber rings are used for sealing).

There are also compensated and uncompensated droppers. When using compensated ones at any point in the irrigation line, the water release will be the same (approximately), regardless of the terrain and location (at the beginning or end of the line).

There are also spider-type devices. This is when several thin tubes are connected to one output. This makes it possible to simultaneously water several plants from one water outlet point (the number of droppers is reduced).

Spider-type dripper - you can water several plants from one water distribution point

Main pipes and fittings

When creating a system for laying a main pipeline from a water source to an irrigation zone, use plastic pipes and fittings from:

polypropylene (PPR);
polyvinyl chloride (PVC);
polyethylene:
- high pressure (HPP);
- low pressure (LPP).

All these pipes tolerate contact with water well, do not corrode, are chemically neutral and do not react to the application of fertilizers. For watering a small greenhouse, vegetable garden, or lawn, a diameter of 32 mm is most often used.

Main pipes are plastic. Choose any specific type: PPR, HDPE, LDPE, PVC

In places where the lines are drained, tees are installed, to the side outlet of which a drip hose or tape is connected. Since they are smaller in diameter, adapters may be needed, and their outer diameter should be equal to the inner diameter of the hose (or be slightly smaller). You can attach tapes/hoses to fittings using metal clamps.

Bends can also be made through special fittings, which are installed in a hole made in the hose of the required diameter (as in the photo above).

Sometimes, after the tee, a tap is installed on each water distribution line, which allows you to turn off the lines. This is convenient if drip irrigation is used for moisture-loving plants and those that do not like excess water.

If you don’t feel like choosing components and selecting sizes and diameters of fittings, you can buy ready-made ones from various manufacturers.

Do-it-yourself drip irrigation: examples of devices

There are many options for designing the system - it easily adapts to any conditions. Most often the question arises about how to organize watering independent of electricity. This can be done if you install a sufficiently large water container at a height of at least 1.5 meters. This creates a minimum pressure of approximately 0.2 atm. It is enough to water a small area of a vegetable garden or garden.

Water can be supplied to the container from a water supply, pumped, drained from roofs, or even poured into buckets. A tap is made at the bottom of the container, to which the main pipeline is connected. Next, the system is standard: a filter (or a cascade of filters) is installed on the pipeline up to the first branch on the irrigation line, and then there is distribution to the beds.

For the convenience of introducing fertilizers on the highway, it is possible to install a special unit. In the simplest case, as in the photo above, it can be a container on legs, in the bottom of which a hole is made and a hose is inserted. A shut-off valve (faucet) is also needed. This cuts into the pipeline through a tee.

If necessary, you can water both shrubs and fruit trees. The whole difference is that the tape or hose is laid around the trunk at some distance. One line is allocated for each tree; bushes can be watered several times on one line. Only in this case you need to use a regular hose into which to insert droppers with the required water flow.

If low pressure in the system does not suit you, you can install (see photo below) or a full-fledged one on the main water supply. They will provide water even to far-flung areas.

Can water be supplied directly from the source? It is possible, but not advisable. And this is not due to technical difficulties - there are not many of them, but to the fact that plants cold water they don't like it. That is why most small-scale drip irrigation systems - for greenhouses, vegetable gardens, orchards and vineyards - use storage tanks. The water is heated in them and then distributed throughout the area.

Drip irrigation: how to calculate the system

There can be one container from which water is supplied to the system - common, as in the picture above, or separate for each area. If there is a significant distance between irrigation objects, this may be more profitable than pulling a main pipeline.

The required volume is calculated depending on the number of plants and the volume of water for their normal development. How much water is needed to water vegetables depends on the climate and soil. On average, you can take 1 liter per plant, 5 liters for bushes and 10 liters for trees. But this is the same as the “average temperature in the hospital,” although it is suitable for approximate calculations. You count the number of plants, multiply by the consumption per day, and add everything up. Add 20-25% of the reserve to the resulting figure and you know the required volume of capacity.

There are no problems with calculating the length of the main line and drip hoses. The main line is the distance from the tap on the tank to the ground, then along the ground to the watering site, and then along the end side of the beds. By adding up all these lengths, the required length of the main pipeline is obtained. The length of the tubes depends on the length of the beds and on whether water will be distributed to one or two rows from one tube (for example, using spider drippers you can distribute water for two to four rows at the same time).

The number of tees or fittings and taps (if you install them) is determined by the number of pipes. For each branch using tees, take three clamps: press the hose to the fitting.

The most difficult and expensive part is the filters. If water is pumped from an open source - a lake or river - you first need a coarse filter - gravel. Then there should be fine filters. Their type and quantity depend on the condition of the water. When using water from a well or a well, you do not need to install a coarse filter: primary filtration occurs on the suction hose (if used). In general, there are as many cases as there are solutions, but filters are needed, otherwise the droppers will quickly clog.

Homemade drip hoses and droppers

One of the most significant expense items when independent device systems made from ready-made components - droppers or drip tapes. They, of course, provide the same amount of water throughout and the flow rate is stable, but in small areas this is not necessary. You can regulate the supply and flow rate using taps built into the beginning of the irrigation line. Therefore, there are many ideas that allow you to distribute water to plants using ordinary hoses. Watch one of them in the video.

It is difficult to call this system drip irrigation. This is more of a root watering: water is supplied in a stream under the root, but it works, perhaps only a little worse and is more suitable for plants with a root system developed deeper. This method will be good for trees, fruit bushes, and grapes. They require a significant amount of water, which must go deep into a decent distance, and this homemade drip irrigation system can provide this.

In the second video, real drip irrigation is organized. This was done using medical droppers. If you have the opportunity to stock up on used material, it will turn out to be very cheap.

The amount of water supplied is controlled by a wheel. From one hose you can supply water to three or four rows - if you take a hose of sufficient diameter, you can connect not three devices to it, but more. The length of the tubes from the drippers allows watering two rows on each side. So the costs will really be small.

Droppers can be used almost without modification. This is the case if the system had a bag. An example is in the photo.

Waste into income - watering for young plants is provided

It is almost also possible to do drip irrigation for house plants. It is suitable for those flowers that love constant moisture.

The cheapest drip irrigation: from plastic bottles

There is the cheapest and fastest way to organize water supply to plants without hoses and large containers. You will only need plastic bottles and small lengths - 10-15 cm - thin tubes.

Partially cut off the bottom of the bottles. So that you get a lid from the bottom. This way the water will not evaporate. But you can cut off the bottom completely. At a distance of 7-8 cm from the cap, make a hole in the bottle into which a thin tube is inserted at a slight angle. Bury the bottle with the cork down or tie it to a peg, and stick the peg into the ground next to the plant, pointing the tube towards the root. If there is water in the bottle, it will run down the tube and drip under the plant.

The same design can be made by turning the bottle upside down. But this option is less convenient: it is more difficult to pour water, you will need a watering can. What this looks like, see the figure below.

As you can see, there is a second option for drip irrigation from plastic bottles. A wire is stretched over the bed, and bottles with holes in the bottom or lid are tied to it.

There is another photo option for using bottles, but with standard droppers for watering. They are fixed to the neck of the bottles and in this form are installed under the bush.

This option, of course, is not ideal, but it will give the plants the opportunity to develop better if you can rarely visit the dacha. And two liters from a bottle can be decisive in the battle for the harvest.

Growing vegetables and herbs in a greenhouse is a painstaking task and requires constant attention. Watering and fertilizing are two essential pillars of obtaining a good harvest. How to reduce the load on the gardener and at least partially automate the processes of caring for vegetables? There are many options for watering - sprinkling and irrigation. A drip irrigation system for greenhouses for irrigating crops is very convenient.

What is drip irrigation in a greenhouse and its advantages.

At proper watering The roots of the crop must receive enough (but not excess) water and a sufficient amount of oxygen. With regular and rain watering, water displaces oxygen from the soil, so mulching is necessary frequently. Drip irrigation in greenhouses does not have these disadvantages.

Drip irrigation provides sufficient moisture in the soil;
The technology ensures the movement of oxygen around the roots;
The soil around the plant does not crust up after drying;
Water is not used to feed weeds and is used 100% by beneficial crops;
Fertilizers can be added along with water;
Possibility of irrigating a large area with low labor costs;
Drip irrigation systems for greenhouses are easy to assemble or make entirely yourself;
Easy to operate and maintain the entire structure. Water moves through the pipes very slowly, gradually warming up to greenhouse temperatures. The constant humidity regime and optimal temperature recreate a subtropical climate in the greenhouse, beneficial for the growth and fruiting of crops.

What is a drip irrigation system in a greenhouse?

Specialized stores have a large selection of ready-made, high-quality kits for organizing drip irrigation. The kit usually includes:

Drip tape with ready-made holes;
Filter of any type: there are many of them sold in different price categories;
Start connectors without taps and with taps and with rubber seals;
Connectors connecting the hose and filter;
Fittings and splitters.

A drip tape is an irrigation tube with holes to release water. The holes can be located at different distances, for example, at 20 cm, 30 cm and 100 cm. The tape is connected to the main irrigation pipe through the start connector, its second end is closed. There may be several branches from drip tapes

by the number of beds on the site. After water is supplied, it begins to ooze from the drip holes.

However, such drip irrigation systems for greenhouses have certain disadvantages:

The service life of such tapes is short;
These tapes can be chewed by insects (for example, mole crickets);
In such a design it is very difficult to regulate the amount of water supplied.

Therefore, many gardeners replace tapes with pipes or rubber hoses with holes they made themselves. Therefore, in addition to installing an irrigation structure, you may need:

HDPE pipe with plug;
Ball valve;
Plumbing squeegee;
Pipe adapters;
HDPE tees if necessary;
Fittings, clamps and couplings.

Among the tools you need to stock up on a drill with drills, pliers, tow or other sealants. You will also need a sharp knife. Many automate such systems using special devices. Automatic drip irrigation allows you to significantly increase the yield of greenhouse crops.

How to make drip irrigation for a greenhouse with your own hands

Drip irrigation system for greenhouses: drawing up a diagram

<Пример схемы капельного полива/div>

At the beginning of work, it is necessary to draw a detailed plan of the system. Indicate on the plan how the beds will be located in the greenhouse and where the pipeline will run to water the plants. The plan should select a location for installing a water tank (you can build a stand for the tank directly in the greenhouse), indicate water sources and the location of the filter, and also show the branching of channels along the beds.

If there is no centralized water supply, care should be taken to install a storage tank or tank in order to arrange automatic drip irrigation for the greenhouse from a barrel. In this case, you will need to install a pump that will pump water. Thanks to a detailed and well-drawn plan, you can calculate the required length of pipes and the number of fittings for branching. So, a drip irrigation system for a greenhouse includes:

Pipes connecting the irrigation system to the water supply or to a container of water;
Ball valve connecting and disconnecting the system;
One filter located immediately after the water source;
One or more drip tapes are connected to the system through start connectors or through dispensing taps; 5. The drip tape can run in the soil, on the ground and in the air above the bed.
Plugs are installed at the end of the drip tapes.

Drip irrigation for greenhouses: installation

Installation of a drip irrigation system

How to make drip irrigation in a greenhouse:

In the water container ( plastic barrel or metal) drill a hole a few centimeters from the bottom with a diameter corresponding to the plumbing fitting. The connection is sealed. A ball valve is attached to the squeegee, after which there is a filter and a pipe.
If the kit includes a filter, it should be installed in the supply hose. Installing the filter is usually not difficult. There are arrows on the body of the device indicating the direction of water movement. If the filter is installed incorrectly, it will not function. If you are planning to buy a filter separately, opt for dismountable systems that can be easily cleaned.
To install distribution pipes, we take polyethylene pipes with a diameter of 40 mm. cut them to the required length. On one side we screw on the tap to transfer to the container, on the other we put a plug. In accordance with the plan, we drill holes in the pipes with a drill of such a diameter that they are 1 mm smaller than the diameter of the rubber seal of the start connectors. We install start connectors or dispensing taps in them through a sealing rubber band.
We connect the drip tape to the start connector through the nut. This procedure does not require special efforts or the use of special tools. The droppers on the tape should be located up if the fly is on the ground and down if at a height of 10-20 cm above the ground. Then we run the tape across the entire bed and place a cap at its end. If you need to branch it in the future, this can be easily done using a splitter. If the tape needs to be extended, connectors will be required, which can also be used for repairs.
You can increase the moisture area for individual crops using spider splitters. The parts are called this way because of the number of outgoing fittings with microtubes through which water enters the irrigation zone. The number of splitters corresponds to the number of droppers on which they are installed.

Before starting the system for the first time, it is imperative to blow it out under maximum pressure in order to blow out all foreign debris from the system. This is how you do regular watering in a greenhouse with your own hands. It is better to install the system at a height of 10-20 cm above the bed. This will allow, on occasion, to easily carry out repairs and adjust the pressure by tilting the system. Now we begin to install automatic drip irrigation for the greenhouse.

How to make automatic watering in a greenhouse with your own hands?

The source of water can be a reservoir (for example, a barrel), fixed at a height of 2-3 m with a valve or ball valve. If you use well water, installing a filter is not a requirement. It is better not to use water from natural reservoirs (from a river or pond), since water with microorganisms will enter the system, which will begin to multiply in the pipes and clog the system.

Tap water requires mandatory filtration.

Let's assume that we have a container for watering. To automate your irrigation system, you will need to buy an additional automatic controller that opens the water supply. The controller will allow you to program watering at certain times and even days. The controller is mounted immediately behind the filter. Using automatic watering in a greenhouse you will save yourself time and effort. The question immediately arises of how to monitor the filling of the container. This process is also automated.

The approximate water consumption for irrigation for one or several days is calculated, depending on the crop being watered, and the container is filled in advance. You can make a pump that will fill the container from a nearby source. This type of irrigation works well at low pressure, is easy to clean, and can be preserved for the winter. To preserve the system for the winter, just disconnect it from the container, lift it from one end and drain all the water.

How to make drip irrigation with your own hands

Let's consider the construction of drip irrigation for a greenhouse in the country using a barrel and a pump.

The modern rhythm of life does not allow us to devote much time to dacha work. But growing a good harvest is only possible if you constantly take care of the plants. For example, cucumbers should be watered before eleven in the morning and until eight in the evening. To make their life easier, summer residents use automatic watering in the greenhouse. Sprinkling, subsurface irrigation or automatic drip irrigation in a greenhouse can be done independently.

Types of automatic watering

The advantages of an automatic watering system are obvious. They turn summer season for pleasure. You no longer need to carry water in buckets or stand for a long time with a hose and wait until the plants in the greenhouse are well saturated with moisture. For example, drip irrigation in a greenhouse is carried out in doses. This means that the plants will receive exactly the amount of moisture they need. The automatic method of irrigation in a greenhouse in the form of sprinkling allows you to spray water in different directions and at different degrees, and this is necessary for automatic irrigation of plants of unequal height. After all, many summer residents grow several crops in greenhouses at the same time.

Sprinkling is automatic watering in a greenhouse, in which water is supplied from above the plants using irrigation with spray nozzles. The principle of operation of the system is simple: a hose is connected to a sprayer, which sprays water throughout the area. The only negative aspect of watering is that a large number of drops settle not only on the soil, but also on the leaves of plants. For many cultures this is unacceptable.

There are two types of automatic sprinkling in a greenhouse - above-ground irrigation, when pipes are laid underground, and air irrigation, when they are attached to the upper parts of the greenhouse. The advantages of air sprinkling are the relative ease of installation and operation.

The disadvantage of this system is the use of well-purified water, as well as constant, good pressure. Open sources such as rivers and lakes are prohibited. This system will also require the installation of a cleaning filter.

But the second method of an automatic watering system using pipes under the soil in a greenhouse is unpretentious to water quality.

In order for an automatic above-ground sprinkling system in a greenhouse, made independently, to work without failures, you will also need good water pressure. Therefore, if the pressure is not enough, you will have to install an additional pump. The disadvantage of such a system is obvious: since the pipes are located on the ground, any breakage is fraught with a long search for an emergency location. To do this, you will have to open the wiring yourself.

The most popular method is drip irrigation systems. It allows you to irrigate plants in a greenhouse only in the root zone, which is the key to good automatic water supply.

Drip irrigation in a greenhouse is a water conduit. Polyethylene pipe with droppers attached to it, it must be placed on a flat piece of land, but if there is a slight slope, then the system must be placed across the unevenness. As for droppers, they come in two types - regular and compensated. The latter are used where an automatic system must compensate for unstable pressure. Such drippers are needed in areas with different levels (for example, an area located on a slope) so that there is enough water for all plants. The automatic watering system in the greenhouse allows you to irrigate certain beds. To do this, special taps are installed that turn the watering of the required areas on and off. This option is needed for competent automatic water supply of different crops growing in the territory of one greenhouse. The advantages of a drip irrigation system in a greenhouse include the ability to install it yourself where there is no plumbing or other sources of moisture. Using hoses, you can simply use a barrel, which must be raised 2 meters from the ground. Such irrigation systems in a greenhouse prevent the development of weeds and reduce the risk of crop disease.

The subsurface irrigation system is similar to automatic irrigation using drips. However, there is certainly a difference. Subsurface watering systems deliver water directly to the roots. Water is delivered using pipes hidden underground, and at a fairly great depth. The subsoil automatic watering method moisturizes plants only in the root area, without forming a crust on the surface. This allows you to loosen the soil less often and creates a favorable environment for plants.

This method is also good because it saves water in the greenhouse. When automatic irrigation systems spray water using drips, most of the moisture evaporates. While underground water supply uses much less water.

Installation of a drip irrigation system

Drip tape is the main element of the system. Find a stable place and place a container of water. For example, a barrel. Ideally, this place will be right in the greenhouse. It must be installed in a shelter from the sun so that the water does not bloom. Next, install the system pipe into the selected vessel. Please note that this must be done just above the bottom of the container, otherwise the debris settling below will interfere with watering. After this, install a tap with which you can regulate the amount of water. Next, lay a polyethylene pipe along the irrigated area. Opposite the beds, you need to make holes in the pipe and install fittings in them. When everything is done, it is necessary to connect the drip tape to them. It should be noted that each drip tape needs a plug. It’s easy to make: you need to cut a piece from it and roll it into a ring, then put it on the end of each drip tape. After finishing the work, do not rush to start the system right away. First check it for leaks and flush it. It’s good if you install a filter that will guarantee the quality of the water in your drip irrigation system.

An electric pump greatly facilitates the automatic method of watering a greenhouse using drips. However, it is also a more expensive option for automatic watering. But you are provided with complete automation of the process.

Installing a drip tape is not the only way to water plants using sprinklers. There is an option to supply water with droppers. In this case, in addition to them, it will be necessary to use hoses.

However, using an automatic drip tape is still much simpler and clearer. It will completely replace the entire set of systems with droppers. The only nuance that should be taken into account is that the life of the tapes is only three years. The system is convenient to use for seedlings when water is supplied exclusively to one point.

To ensure full automation of a drip irrigation system, a controller is used that will operate from the network. In an hour, a drip tape can easily produce about 600 liters. To collect water, you can use not only a water tank, but also a Eurocube: it is sold ready-made and does not require construction, it can be installed in any part of the dacha closer to the irrigation site and ensure that there is always water inside. The Eurocube is made of polymer materials that are not afraid external influences, and fortified metal grille for strength and safety. This is the best option for small modern dacha with modern equipment.

Automatic sprinkling

To mount it yourself this system watering, you will also need pipes with a diameter of 20 mm. The kit will include taps and sprayers. If the nozzle is chosen correctly, then you will not need a lot of pressure, since the moisture will come out in small portions and will not crush the soil. It is also necessary to take into account that the water should be sprayed in the form of drops and not streamed. Otherwise, the roots of the plant will simply rot.

An automatic rain irrigation system called “snail” is popular among summer residents. Water is supplied to the nozzle, which is located a short distance from the soil. The liquid is sprayed in umbrella-shaped droplets and covers a large area.

You can also make a second option called “ring”. To do this, you need to roll the hose into a ring of the required diameter. Next, holes are made in it, which will spray water.

If you don’t want to do the sprinkling yourself, you can use sprinklers. By the way, with their help you can simply water plants, both in the greenhouse and outside it.

Subsoil irrigation

Its installation should begin with the preparation of pipes with a diameter of two to four centimeters. Thick hoses can be used. Preparing the pipes involves making two-millimeter pores in them. The second stage is to prepare the beds. First you need to remove the substrate. The depth should be 30 cm. Next, fill the surface with gravel and put plastic film on it. This is necessary to ensure that water does not go deep into the soil and erode its layers. Then you need to lay out the pipes or hoses, at a distance of about 50 - 90 cm from each other. You need to put a film on top of the pipes, the width of which is no more than 20 cm, and sprinkle with the previously removed substrate.

Before planting plants, you should check how well the irrigation system is working. To find out, you need to dig up the soil after seven days and see if the subsoil automatic irrigation copes with the task assigned to it.

Watering rules

It doesn’t matter how you organize watering the plants: using a drip tape, sprinkling or subsoil system. After all, all these modern irrigation techniques will not work correctly if the rules of water supply are neglected.

Avoid using cold water in the greenhouse. Ideally, let the liquid sit and warm up in sunlight.
It is necessary to water evenly. A portion of the drops should be completely absorbed, then watering should be continued.
To retain water in the ground, the holes with crops must be covered with straw, which will not allow the water to evaporate for quite a long time.
To prevent the soil from becoming overly wet, you should check whether it is actually dry before watering. This can be done simply using a metal pin. It must be stuck into the soil next to the plant to a shallow depth. The soil sticking to it will indicate that there is no need to water it yet.
The composition of the water must be of high quality. Use a filter for cleaning. This is especially true when sprinkling and watering with drops.

By using auto-irrigation, which you think is more effective and suitable for your crops, you can achieve amazingly high yields. The main thing is to take into account all the nuances and calculate the amount of water required for the greenhouse in proportion to the needs of the plants and the area of the building.

Automatic watering in a greenhouse

In SNT Raduga near Moscow, automatic watering was organized in the greenhouse. The owner of the plot, Dmitry, wanted to get a good harvest of tomatoes without spending a lot of time caring for them.

The main thing for Dmitry was to organize everything himself and install everything with his own hands.

In order for everything to work out and work, the engineers of our company helped him.

Client Feedback

Automatic drip irrigation system in a greenhouse

There are several greenhouses on the site in which various crops are grown, such as tomatoes, cucumbers and peppers.

First of all, it was necessary to make automatic sprinkling for the tomato bushes.

The automatic drip irrigation system in the greenhouse with tomatoes was installed by the owner of the site independently with the help of engineers from the Good Rain company.

For automatic watering, the ESP RZX Rain Bird controller is used; it allows you to divide the irrigation system into 4 zones and run each separately, saving on the pumping station.

You can also set different times for each crop on the remote control.

It's very simple:

You save time - when you come to your dacha, you can relax more and water less.
Automatic drip irrigation in a greenhouse always ensures uniform irrigation both in terms of soil saturation with water and time of day.
The American system is reliable and will not let you down - you can go on vacation, and the tomatoes will grow on their own.

Automatic watering of tomatoes

Tomatoes are a very capricious crop to grow.

they require increased attention constantly. To get a good harvest, you need to constantly ensure that nothing interferes with their growth.

Automatic watering of tomatoes solves the issue of uniformity of irrigation and the amount of moisture supplied.

IN greenhouse conditions tomatoes are not affected by external pests, and moisture goes directly to the root, without damaging the leaves and fruits.

Design

An irrigation device based on drip irrigation hoses does not require a special project if the system is organized in a regular greenhouse on summer cottage.

Do-it-yourself tomato watering system in a greenhouse

In Europe, it is customary to plant plants in greenhouses in increments of 33 centimeters; this is what determines the distance between the droppers on the hose.

You can make a tomato watering system with your own hands, taking this fact into account.

Plant tomatoes at intervals of 33 centimeters, then water drops will flow exactly under the root of the plant and you will avoid excessive water consumption.

The tomato watering system in a greenhouse can be organized in another way.

For example, you can buy a hose without drippers, lay it next to the plants, and then additionally install drippers for drip irrigation in the tube.

cucumbers

Irrigation of cucumbers can be arranged according to the same scheme as tomatoes.

The irrigation lines are also connected to the roots and the cucumbers grow well.

Plants climb along the mesh and hang quietly and grow to the desired size.

The sprinkling regime will be different. The automatic watering control panel allows you to separately program the irrigation of cucumbers at any time of day and duration.

This is what the hose looks like. To ensure that it lies flat, you should buy drip irrigation pegs that securely fix it to the surface of the ground.

Pegs come in two colors:

They are no different in their properties.

To make it possible to forcibly turn off zones, ball valves are used.

Such ball valve is installed on the line and blocks the desired section of the hose to reduce water consumption.

Tomato watering system

Do you want large red tomatoes to grow, like Dmitry’s?

A tomato watering system will solve this problem.

Of course, you need a little knowledge about caring for plants in general, but the Rain Bird system from the USA will help save a lot of time on caring for the site.

DIY drip irrigation in a greenhouse

Do-it-yourself drip irrigation: diagram, video.

Regular dosed watering is the key to a high yield of vegetables. Do gardeners solve this problem every season? how to simultaneously grow a bountiful harvest of tomatoes and cucumbers in a greenhouse, while spending less water and physical effort on cultivating the land.

Saturate the soil with moisture minimal costs labor can be done using a drip irrigation system. You can build an irrigation mechanism in a greenhouse with your own hands, using a ready-made kit or selecting hoses, a filter, drip tape and fittings yourself.

Why do you need a drip irrigation installation?

With the beginning of the use of spot irrigation, the yield of cucumbers and tomatoes both in the greenhouse and in open areas increases by 30%, due to the fact that the micro-drip irrigation mechanism, in manual or automatic mode, delivers moisture directly to the plant roots in the right dosage with the required frequency.

In this case, plant roots develop in a small area and the plantings do not thicken.

Expensive drip irrigation systems operate in multi-program mode, have a control unit and a built-in timer.

Crops grown in a greenhouse are moisture-saturated plants; they contain moisture from 75 to 97%. As a result, they require a large volume of water to ripen, for example, the water consumption coefficient for tomatoes is 90–150, for cucumbers 100–150. Plants are especially sensitive to lack of moisture during the period of initial growth, when the roots have not yet strengthened.

Both soil waterlogging and drought are dangerous, so automatic irrigation is preferable to manual irrigation.

What is the mechanism?

The principle of operation is to automatically supply filtered water directly to the root system of each plant through droppers. Spot irrigation is installed at the dacha both in open space and in the greenhouse.

How to install a drip irrigation system for greenhouses yourself?

Installation is carried out in 3 stages. Before starting work, calculate the required length of the main pipe, tape or drip hose, taking into account the location of the beds and rows of plants in the greenhouse.

It is necessary to take into account the number of droppers, starting fittings and adapters on the prepared diagram.

For convenience, it is better for the gardener to buy a ready-made drip irrigation kit for greenhouses. When choosing a set of drip irrigation system, the type of control (manual or automatic water supply), the ability to change the humidification mode, the size of the covered area and what type of water is important. vegetable crops The pitch of the droppers is calculated.

Spot irrigation should be assembled in accordance with the instructions included with the kit.

Stage 1. Materials

To install irrigation in a greenhouse you will need:

1.Drip tape or tube.

Each gardener decides for himself whether to choose a PVC pipe or tape, based on his financial capabilities and the characteristics of the greenhouse. The droppers are mounted into the drip tape at a certain distance, and holes are made independently in the PVC tube for a targeted release of moisture.

The tube is made of polyvinyl chloride, the diameter of the pipe should not exceed 15 mm, in this case the pressure required for irrigation is created. It is advisable to choose a dense, black, light-stabilized hose.

If you use a transparent hose and expose it to sunlight, after a few days the pipe will turn green, algae will begin to multiply inside and this will clog the filters.

A PVC pipe or tape with droppers is responsible for the period of operation of the system and the quality of irrigation.

Their consumption is equal to the sum of the treated areas plus a small allowance for the plug at the end.

Drip irrigation in a greenhouse: systems and reviews

There are 3 types of drip tape: emitter, labyrinth and slotted. They differ in the principles of moisture distribution inside, the materials from which they are made and their service life.

Labyrinth drip tape is considered the simplest and most accessible. Inside the thin-walled tube there is a labyrinth-shaped channel. This structure allows you to reduce water pressure and redistribute the movement of flow.

The owner needs to ensure that the holes in the labyrinth drip tape are located on top and do not turn over.

The slot system is an analogue of the labyrinth system; it can withstand significantly greater loads due to the fact that the irrigation channel is located inside the labyrinth.

Drip tape with emitters (microdroppers built into the surface of the tubes at distances of 10-30 cm) is designed for 4-6 service seasons. Compared to other types of drip tapes, the emitter tape is resistant to contamination due to the flow turbulence formed in it.

The thickness of the drip pipe is 0.125–0.375 mm, on average 2 mm. Thick material is chosen for rocky soil where the risk of damage is high.

The average irrigation flow is 1-1.5 l/hour. The distance between droppers for cucumbers is 15–20 cm, for tomatoes 30 cm.

2. Main water supply.
The length of the main hose is equal to the distance of the water tank or well with a pump from the beds with plants. Its diameter is no less than 32 mm. The main line is placed directly on the beds and combined with taps and starters. To prevent the main pipe or hose from moving, it is pressed to the surface of the ground using wire clips of arbitrary diameter.

The main wire can be an ordinary pipe for supplying cold water.

3.Fine filter.
The incoming water flow needs filtration; without it, soil contaminants and foreign objects will damage the device in a short time. Irrigation mechanisms are harmed by biological blockages such as algae and silt; mechanical in the form of sand, stones and chemical nature - calcium deposits.

To remove blockages, use special reagents and regular washing at least once a week. The filter is installed in the main hose.

4.Mini starters, taps, adapters, plugs, fittings.
Using the initial starter at the dacha, they regulate the supply of liquid to each bed, turn off unnecessary ones, while leaving the rest to work.

This is important for a greenhouse, since plants with different water consumption grow nearby.

4. Droppers.
The kit includes droppers of different structures, for example, in the form of knitting needles with a sharp end.

A hose from a mini-starter is connected to them, and water penetrates through the spoke to the required depth to the roots. There is a compensated dripper that distributes water flows between neighboring plants.

Droppers are divided according to performance level - 0.6-3.8 l/hour.

The number of droppers corresponds to the number of plants in the treated beds!

Stage 2. Cost calculation

The gardener needs to prepare a diagram of the greenhouse indicating the size of the beds. The dots indicate the location of plants in the rows. A main pipe is placed along the beds, and a hose with droppers is run from it to the beds so that the flow goes to all the plants.

Calculate the length of the main pipe, the sum of the lengths of drip tapes or PVC wires, the number of starting fittings, taps, droppers, and splitters. The result will be individual for everyone, since the consumption depends on the size of the beds in the greenhouse, the frequency of planting and the type of material, how many seasons it is designed for, and so on.

Depending on the material, irrigation tapes and components are designed for a different number of years of service.

At the end of the summer season, the system is cleared of blockages, twisted and stored.

Stage 3. Installation and launch of the system

The pipeline is connected to a water source. The container with water must be raised to a height of at least 15–25 cm to ensure pressure and movement of the liquid. At your dacha, you can install a Eurocube for watering - it is more convenient than a barrel and its installation is easier. To calculate the pressure, you need to keep in mind that raising the water tank by 1 meter increases the pressure in the system by 0.1 bar.

The main line is placed at the ends of the beds, secured to the ground and holes drilled for taps or fittings with a diameter of 15 mm. Installing drip tape involves attaching it to taps and laying it along rows of plants. At the opposite end, the tape is closed with plugs or tied with wire or rubber band. Optionally, a control unit is installed next to the filter, and water will be supplied in an automatically set mode.

Before the first start, the system must be flushed.

Ten advantages of the system

Thanks to uniform injection, the soil is not washed away during point irrigation, the ecology of the soil composition is preserved, and the land does not sag.
The irrigation tape is distributed over the ground in such a way that all plants are equally supplied with water.
Slowly wets the earthen ball, while the water does not remain on the leaves, but penetrates into the roots of the plants. For tomatoes and cucumbers in a greenhouse, it is important that water does not fall on the leaves during irrigation.
This causes burn spots on the leaves.
Water from the soil surface does not evaporate and therefore does not create excess humidity in the greenhouse. At optimal temperature and humidity, diseases of vegetable crops develop less.
Watering with your own hands takes much more time and physical effort than automated system irrigation.
When growing plants in greenhouse conditions, the yield increases by 2–3 times due to careful “smart” moistening. Water is not wasted on neighboring areas, paths.
With the help of an irrigation system, large greenhouses or open spaces are treated.
The drip irrigation method is capable of producing a good harvest even on “difficult” soils, for example, heavy or too loose.
The automated system allows you to simultaneously perform several hydraulic operations: moisturize plants, apply fertilizer, use protective equipment in the required dosage.
Water savings compared to the conventional sprinkling method are more than 50%.

Conclusion

Do-it-yourself watering has long ceased to be the only solution for gardeners. An automatic irrigation system, despite the initial investment, pays for itself quickly and frees up the energy of summer residents for other work.

The traditional method of watering greenhouses in summer cottages is a watering hose, which has to be moved from bed to bed.

Do-it-yourself drip irrigation in a greenhouse will help simplify your work and reduce the time spent caring for plants. With its help, you will increase the productivity of plants and save yourself from unnecessary work, while spending a minimum of money. Making a drip irrigation system with your own hands is not a difficult task, but you need to be patient, think through the details and make the necessary calculations.

Benefits of drip irrigation

Watering is vital for plants during the hot, dry summer months.

Having correctly organized drip irrigation of a greenhouse at your summer cottage with your own hands, having carefully thought through the design of an automatic watering system, you will soon experience the numerous benefits of drip irrigation:

a drip irrigation device will significantly increase productivity;
drip irrigation in a greenhouse allows you to directly moisten the root zone of the plant, while preventing water from getting on the leaves and fruits;
due to local watering, the number of weeds is reduced and their further spread in the rows of the greenhouse is eliminated;
economical use of water.
You can save up to 50% water, effectively increasing plant productivity. This factor is especially important for regions with water supply problems;
by installing a special container in which water from common system water supply, you can water the greenhouse with warm, settled water. At the same time, you can create an optimal environment for plants, since the water for irrigation will be the same temperature as the ambient temperature;
increasing the efficiency of liquid fertilizers, their absorption by plants becomes significantly higher;
the device of drip irrigation of the soil prevents the deterioration of the soil due to its compaction and preserves the fertile layer of soil;
this irrigation system eliminates the need for a drainage system;
Growing greenhouse vegetables and flowers occurs with the least amount of labor: all efforts come down to opening or closing the tap.

System design

Designing an irrigation system involves a detailed study of the geometry of the site, drawing up a diagram of the location of plants in the greenhouse and marking the watering zone.

After this, you need to calculate the volume of water consumption for each zone separately, as well as calculate the productivity of the water supply source. Next, you need to draw a pipeline diagram and, based on the results of the calculations made and in accordance with the project, purchase the necessary components.

Selection of connection elements and organization of drip irrigation

In order to provide drip irrigation in a greenhouse, it is necessary to organize a slow supply of water through tubes from the tank, which should be installed at a height of approximately 2.5 m.

First you need to choose the location of the pipes in the greenhouse. Distribution pipes are installed on both sides of the water tank, which is connected to the water supply using detachable connections. Near each plant, a special hole is made in the pipe for a nozzle, through which water will flow to the root system.

To regulate the fluid flow to prevent waterlogging of the soil, use a tap or automatic sensor.

In summer cottages, to equip greenhouses with a do-it-yourself drip irrigation system, special small-diameter tubes are usually used. Fittings are purchased for them, with the help of which it will not be difficult to connect all the components of the irrigation system with your own hands. However, to do this, it is necessary to study the plan for planting the greenhouse with plants and create a drawing according to which a unified irrigation system will be assembled.

During installation, various types of connecting elements are used: tees, plugs, couplings.

Water penetrates directly to the roots of greenhouse crops using special tips (droppers). They are divided into internal ones - built into a hose or pipe, as well as many types of external ones (droppers with regulated or unregulated water supply, pressure-compensated and non-pressure-compensated designs). To install external droppers, you need to make holes with a diameter of 3 mm in the pipe using a special tool.

To equip an automatic drip irrigation system at your dacha with your own hands, you need to use special devices: controllers, solenoid valves, sensors.

Installation of irrigation system

Based on the drawing of the drip irrigation system, holes are marked in the distribution pipes, which should be located in the same plane.

It is recommended to firmly fix the pipe when drilling. Fittings and seals are installed in the resulting holes. After this, the pipe is connected to a water source, but you need to remember to install a special filter. The disc filter serves to significantly extend the service life of the drip tape. It is also strongly recommended to flush the pipe to remove any chips that form when welding holes.

After completing all preparatory work You can start attaching drip tapes to the pipe and supplying them to each plant.

Which drip irrigation is best for a greenhouse: an overview of different systems

The special tape is a thin-walled tube, which takes on a round shape when liquid is supplied. Plugs are installed at the ends of the drip irrigation tapes.

Test run of the system

When installing a drip irrigation system with your own hands, a mandatory step is its test run.

It consists of sequentially opening the taps and uniformly moistening the soil. It is also recommended to monitor the performance of the droppers.

With a high-quality organization of a drip irrigation system at your dacha with your own hands, the plants in your greenhouse will receive moisture in sufficient quantities and at the right time, and positive results Your work will not be long in coming! Drip irrigation will become your reliable assistant at your summer cottage and will last for many years.

Greenhouse conditions: how to install an automatic irrigation system in a greenhouse with your own hands

Self-watering

Everyone who has a dacha or garden plot, knows what self-watering is and how important it is to provide plants with timely care. They must be given the opportunity to freely absorb sunlight, sufficient heat, and regularly fertilize and water the soil.

However, it takes quite a lot of time and effort to water regularly, and you also need to strictly adhere to the schedule and amount of water.

Therefore, every summer resident, to one degree or another, thinks about how to automate this process, because at the dacha, first of all, you want to relax and unwind.

Self-watering system

There is a solution! This is a self-watering system that you can make with your own hands at the dacha.

Do-it-yourself drip irrigation in a greenhouse - the task is simple, the effect is colossal

In modern gardening stores you can find everything you need to collect it.

Today, there are two types of automatic watering - sprinkling and drip irrigation.

When sprinkling, plants are watered from above using special spray nozzles that spray water.

This system is used for both greenhouse and other garden plants, lawns.

Drip self-watering is the most profitable. It is used for flower beds, bushes, vegetable gardens, as well as greenhouses. Special hoses with holes are laid along the beds, and from each hole water slowly flows to the roots of the plants.

Self-watering for a greenhouse

Before you make self-watering in a greenhouse with your own hands, you need to understand what it should consist of and buy the necessary parts.

In order for the process to be automatic and uniform, pressure must be created inside the system.

To do this you will need:

Water supply container;
Mechanism for water supply (solenoid valves, controller for them);
Small diameter plastic pipes;
Pipe fittings;
Droppers;
Pump as well as float valve.

How to make self-watering for your greenhouse

First of all, make a plan for the location of the pipes in the greenhouse and determine the number and distance of the holes for the droppers from each other.

Cut a light-proof garden hose, no more than 1.5 millimeters thick, into pieces according to the dimensions of the plan.

Connect the parts together in the required sequence using fittings.

Using an awl, punch holes and insert droppers into them.

To prevent them from jumping out under the pressure of water, you need to make holes of such a size that the droppers enter them with force. The designs of some of the droppers provide for the distribution of water through microtubes for 2-4 plants.

Place a container of any size above the level of the hoses extended above the ground.

You can fill it manually, or connect it to a water supply (well). In this case, it is necessary to equip the container with a float valve, which regulates its filling level.

Use a pump to supply water from the container to the hoses.

Equip the pipe lines with ball valves if you want to open them manually, or with solenoid valves.

In this case, you will have to purchase a controller to regulate their opening and closing.

But, if you want to get a high-quality result without significant labor costs on your part, and do not have the desire to do everything yourself, use the opportunity to order a self-watering system for a turnkey greenhouse right now.

Of course, many gardeners believe that an automatic drip irrigation system requires a lot of money, time and effort, and in general such a procedure is risky. That is why creating a semi-automatic watering system from plastic containers is optimal for gardeners who decide to save money. Such a device practically does not take much time, but costs mere pennies.

For watering in the greenhouse from plastic bottles you will need:

A needle or awl, as well as scissors;
Nylon or cotton fabric, gauze;
Empty plastic bottles with caps;
Shovel.

In many cases, a container with a volume of 1 to 2 liters will be required.

This volume is quite enough for 1.5-3 days of watering. It all depends on weather conditions and the characteristics of plant varieties. Sometimes you can use larger bottles, but you should understand that they will take up much more space next to the beds. Gardeners themselves choose what is more important: the area of the beds or the autonomy of watering the plants.

Stage 1. Wash plastic containers, erase labels from them, if any.

Stage 2. Using scissors, trim the bottom of the bottle by about 5 cm.

Stage 3. Use a hot awl or needle to make holes in the plastic lids. The diameter and number of holes will determine the amount of liquid that will enter the soil.

Stage 4. Place a piece of gauze on the inside of the lid. The fabric will act as a kind of filter and will not allow the holes to become clogged frequently. If there is no gauze, then you can use nylon or cotton cloth.

A mesh cloth should be placed inside the container to prevent clogging.

Stage 5. Dig holes next to the plant with the same diameter as the diameter of the container, approximately 10 or 15 cm.

Stage 6 - insert a container covered with a lid into the hole. We can assume that such an automatic drip irrigation system ready to use. Next, you should do similar actions with other bottles in the greenhouse.

Important! If you place bottles in the soil in this way, one problem may arise. Debris and soil particles may fall into them from above. Gradually the hole becomes clogged and there will be a need to remove the container and clean the structure.

There are two ways to solve this problem:

The first way is to place plastic containers the other way around, i.e. upside down. Using this method, you need to make holes in the bottom, and protect the container on top with a lid from debris.
The second way is to make volumetric nozzles on bottles.

There are two ways to improve your irrigation system:

The first method is to replace all the holes on the lids with special droppers, which are sold in stores. Droppers They conduct moisture to the seedlings much better, and they also clog plastic bottles less.
The second way is to run a hose from a water supply into the greenhouse with branches and insert containers into each of them. Thanks to this action, there is no need to refill the bottles yourself. You just need to open the valve and wait a certain amount of time.

DIY drip irrigation from plastic bottles It's not difficult to do. It is enough to familiarize yourself with the main technological stages. In order to properly make an irrigation system for cucumbers, tomatoes and other vegetable crops grown in a greenhouse, you should look video instructions from experienced summer residents.

At the moment, there are 3 automatic crop irrigation systems in greenhouses - subsoil system, drip irrigation and sprinkling system. Details below.

You need to install automatic sprayers before planting plants in the ground (you can learn more about this system by watching a video tutorial on the manufacturer’s website). The garden hose needs to be run through the center of the greenhouse, make required quantity branches for irrigation, based on their greenhouse size. Then the sprayers are installed; you can use either a homemade version or a ready-made purchased one. Purchased ones are better to use, and some models include a built-in system for controlling spray and water pressure, they are not of the underground type, they are mounted at a distance of 80 cm above the ground, but the height can be adjusted depending on the height of the plants.

If the sprayer is placed at a height of more than 2 m, this can lead to the death of young shoots.

The drip irrigation design is installed in a greenhouse with a large area. There are various methods of supplying moisture to the root system. You can also install this system manually, but it will cost more than a rain system.

The kit is mounted like this:

Take a large container for water, for example a tank.
Installed at a height of 1 m from the ground at the entrance to the greenhouse.
The source for this system can be a water supply or a well, from which the main distribution pipe is taken.
An irrigation pipe is mounted to the latter; the number of these pipes depends on the number of beds.
Small diameter nozzles are attached to the main pipeline.

At the end, attach the drip tape to the main irrigation pipe. Installation of the drip system is complete. You can organize any irrigation system with your own hands.

Optimal watering of greenhouse beds

Each period of plant development requires its own amount of moisture. The greatest peak of need occurs at the moment of seed germination. Large quantity moisture is required for seedling growth and rooting. Soil moisture should be at least 60%. When watering, the entire volume of soil should be taken into account, and not just its upper surface. With insufficient watering, the soil dries out, and with excessive watering it leads to rotting of the plants, so moisture must be maintained at a depth of 50 cm. The water temperature should not be lower than room temperature, 23–25 °C. Under no circumstances should you water with cold water; this can lead to root rot and, in hot weather, cause shock.

There are watering rules:

At the initial stage of plant growth, it is enough to take care of moistening the root layer of soil, but without allowing waterlogging;
When watering susceptible to diseases and self-pollinating plants, you need to ensure that moisture does not fall on them;
If watering plants is done with a hose, you need to correctly calculate so that the stream is not strong, so as not to wash out the plant’s horse system;
The irrigation rate and quantity should be reduced in cloudy weather;
Irrigation water should not contain harmful impurities.

It is necessary to check that the water does not contain phenol compounds, various impurities and organic acids. Vegetables die with high levels of various impurities, and with a high iron content, there is a risk of burning and browning of plants.

Growing in late spring, summer, at high temperatures and low humidity requires cooling and adequate watering, and, in contrast, requires minimal irrigation in early spring, winter and in cloudy weather, especially fog. Temperatures should not be allowed to drop; this will lead to the death of plants.

The maximum rate in summer is about 10-12 l/m2, in winter – 5 l/m2.

The rate of watering depends on the plant itself; this must be taken into account when sowing mixed. The peculiarity of greenhouse soil also plays a role special role If light soils are characterized by frequent watering with small rates, then heavy soil needs rare watering in large portions. The timing of watering is determined by the appearance of the plant, soil moisture to the touch, a physiological method for determining the concentration of cell sap, and a laboratory method. The amount of moisture can be set by appearance plants by the color of their leaves. If there is not enough moisture, they take on a darker color.

How to properly feed seedlings in a greenhouse

Seedlings in a greenhouse are fed using the root method; fertilizers are dissolved in water for irrigation or poured dry onto the ground. This is the most universal method of complementary feeding, but there is also a foliar method, with the help of which plants are fertilized by spraying. To use, you need to know whether such a system is suitable for a given plant. Every plant needs fertilizer, which includes organic and mineral components. In order for the harvest to be of high quality, the seedlings need to be fed.

Plants most often need:

Azote (watered with chicken droppings);
Phosphorus (an artificial type of fertilizer);
Potassium (an artificial type of fertilizer).

Perforated greenhouse tape and PVC binko film allow fertilizer to penetrate into root system plants. They also help maintain a special microclimate in the greenhouse and heat, and also protect (if closed tightly) plants from adverse external factors, which allows the plants to receive more nutrients and moisture.

A greenhouse or greenhouse has its own microclimate, which is easily controlled, making it very convenient to grow plants. After all, you don’t have to worry about the seedlings being damaged by sudden temperature changes or unplanned precipitation.

Watering rules:

Young seedlings are watered often, but moderately, and adult plants are watered abundantly, but rarely;
A ripe crop needs frequent watering so that it does not need moisture;
When the leaves curl, the seedlings need to be watered, and if cracks appear on the seedlings, watering should be reduced;
The heifer needs regular ventilation to avoid creating a greenhouse effect, which has a detrimental effect on plantings;
It is necessary to take into account plant options; some are watered at the root.

To ensure ideal watering, a drip irrigation system is installed. Depending on the seedlings, watering is done several times a week. It is necessary to adjust the depth of watering. The soil must be moistened at least 60%, this is easy to check. If a lump of earth easily sticks together in your hand and then crumbles, then the moisture is normal.

What is the best watering for a greenhouse?

Irrigation by sprinkling is carried out from above or below. The most the best option considered to be the top piping system. This type of irrigation has a small number of pipes for strong water pressure. Sprayers are installed permanently or can be rotated; they ensure optimal distribution of moisture throughout the greenhouse.

The system has disadvantages:

If moisture gets on the leaves of a plant on a sunny day, a burn may occur;
After watering is completed, it is necessary to remove moisture from the leaves of each plant, which makes the watering process more labor-intensive;
Each branched system requires high water pressure, which entails careful installation of expensive pipes;
Some of the water evaporates before it reaches the root system, resulting in inefficient water use.

This irrigation scheme is the most labor-intensive to install; it also requires constant monitoring and significant knowledge in land reclamation. Such a system is necessary for growing certain cultivated plants that do not tolerate high humidity.

Watering a greenhouse (video)

In conclusion, it is worth noting that with properly selected and adjusted watering, caring for any plants will not only be carefree, but also effective, and the plants will be rewarded with a high yield.
