These and other benefits are not difficult to get at its disposal. It is enough to study the drip irrigation in greenhouse with his own hands. Application of this technology in practice is described in detail in this article.

Basic definitions - what functions are performed by drip irrigation for greenhouses

In this article, methods of cultivation will be considered cucumbers, Tomatoes, and other vegetables and herbs in a greenhouse. It is better than the example in the photo corresponds to domestic weather conditions. This specialized structure is not difficult to build on the site with his own hands. With the help of the following tasks:

1. Provide protection of plants from excessively low temperatures, wind loads. It should be noted the extreme weather changes in recent decades. In central Russia can not exclude frost in May, September.
2. The greenhouse will ensure creation of favorable conditions for the rapid maturation of the fruit.
3. It will prevent the ingress infectious agents. This will have a further positive impact on the quality of the crop.
4. If the products are grown for commercial purposes, early maturation will set high prices and large profits.

Toeplitz advantageously be used in conjunction with point watering system. With its help provide dosing of moisture, nutrients and protective agents. rain protection implies the need to use artificial irrigation system.

Here are answers to the following important questions:

1. For some cultures fit this decision?
2. How long should the water compared to "traditional" methods?
3. Will there be enough drums, or be sure to connect to the centralized water system? How to make a connection, to ensure a good seal?

8. How much should water them during the day?
9. How to use the system? How to collect it? How to choose the correct setting?

Separately, the features of the finished sets of equipment from the manufacturer. Also studied the possibility of creating an efficient irrigation system with his own hands from improvised means, standard components.

Different types of irrigation, the advantages and disadvantages

Should carefully examine what are the main types of irrigation vegetable garden. This will help you choose really the best option, taking into account the physical, time and other costs.

This type of irrigation allows accurately dosing liquid to use it together with fertilizers. inexpensive equipment required for playback technology. The main disadvantage is the complexity of procedures. They can be used for the cultivation of a relatively small number of seedlings. They are suitable for watering trees, shrubs Location on. Labor costs in the care of the plants in the greenhouse will be excessive.

When working in the greenhouse, this technique creates additional inconvenience. One has to move between the individual grooves, which are filled with mud. In an enclosed space the temperature is higher than outside, so evaporation is too fast. Excessive humidity increases, water flow increases, nutrients and protective substances. However, it should be noted that this method is simple and fast performing work operations.

Such equipment is well suited for the creation of automatic watering systems with a large radius. They perform their functions with special sprinklers. The pipeline create high pressure, which should be considered when choosing the right type of hose, pumping equipment.

Different types of sprinklers may be used in combination with the electromagnetic valves 220 V, 24 yl V. Reduced voltage increases safety in wet environments. For efficient operation of nozzles connected to a water tank, gravity flow is not sufficient. Set the pump to ensure the desired pressure.

Such systems perform their basic functions efficiently. But they consist of a large number of complex electrical and mechanical components. This increases the cost and reduces reliability, increases the risk of breakdowns. Excessive humidity provoke corrosive processes that destroy metals. She, along with heat creates favorable conditions for the development of infections.

It is more difficult than the use of conventional watering, but cheaper than sprinkling. It is used for automatic irrigation and fertilization in private greenhouses and similar commercial facilities.

Pros and cons of drip irrigation: the correct definition with the parameters of the system

After spending ten minutes on the Internet, you can find and buy a set of components for installation in a greenhouse respective system. Before proceeding to a detailed study of the individual components, it should be noted the main advantages and disadvantages:

• Liquid is supplied to the root zone in small doses. It does not displace the air, not leaches nutrients as in intensive irrigation.
• Application of this technology is useful for tomatoes and other plants, because for every row you can customize the optimum irrigation schedule. Moisture is delivered in sufficient quantity, regardless of the distance from the tank.
• You do not need excessive pressure in this design. Absence of electromechanical blowers and other complex components allows cost-effectively equip a large greenhouse.
• Drip irrigation is not difficult to automate. Electronic dosage consume little energy. To power these devices are quite standard capacity battery (batteries). There is no need to connect to a network of 220 V.

The advantages of such a decision is necessary to rank the relative ease and reasonable cost. After studying the manual, any user perform the installation correctly without the help of electricians, plumbers, and other specialized professionals. When used properly, automation equipment will be significantly reduced labor costs to care for plants.

What is drip irrigation: the choice of component parts and components

In this embodiment, the tank is connected to the centralized water system. The system is a filter with a disk cartridge that works effectively under a certain pressure. To create the necessary pressure is sufficient to apply a pump of small capacity submersible. The main line formed of polyethylene pipe with diameter of 16 mm. To it are connected through a "T" and "T" -shaped fittings drip tape with holes.

Tapes for drip irrigation

These products are designed to transport the right amount of water to the plants. The following are features of different types of drip tapes:

• The internal channel in a zigzag form not used often. Such a modification can be purchased inexpensively. But it is considered obsolete, as it is not able to provide an even distribution of irrigation in the different sections of the route. Also a small price advantage is the low speed displacement fluid that provides good heating before entering into the root zone.
• Slit-design It performs its functions efficiently, inexpensive. Complex configuration prevents the penetration of holes into the roots of the earth particles and other foreign objects. The output of the dropper is designed in such a way as not to create the jet. This design solution prevents soil erosion and damage to the delicate leaves.
• Tape-type emitter more expensive than the embodiments described above. But they have the best consumer characteristics. A special form of the channels prevent congestion mechanical impurities, even when using a weak pressure. compensated type models provide a uniform flow of water in the small and large distance from tank at a system pressure of 0.2 atm. and higher.

Note! Price tapes Tuboflex domestic production is about 6 rubles. m for running. This investment will pay off in practice. This product is ideal for the creation of an automated irrigation system. About him publish positive reviews end users and professionals. It stands Specialized ribbon is only slightly more expensive than a high-quality garden hose.

To find out which is best drip tape, it is necessary to consider the following factors:

• Manufacturers offer models with a step between the outlet groups of 10-120 cm. You must choose the option that corresponds to a certain order of seating.
• Similarly, the products can rob a rate of 1 to 2.5 liters per hour.
• The thickness of some tapes can be up to 20 mm. The larger the value, the higher the strength, mechanical resistance.

To calculate the length of the drip tape, you can use the following table:

The distance between the belts is determined taking into account the characteristics of the ground. For sandy soils recommend to install drip irrigation line is not less than 30-31 cm from each other. When installing the system on loam distance is increased by 40-50%.

How to put the tape with your hands, you can find out with the help of the video:

Detailed description of how to mount watering conveyor, below. This section describes only the basic rules and some useful tips:

• Special fittings are used to create branches from the main thoroughfare running water.
• In the transport state of the slit closed film. It is removed immediately before the stack system.
• The outlets set up. This prevents contamination and provides free air outlet with water supply.

To find out how much the implementation of the project, it is necessary to specify the price of all its component parts.

Start-connectors for drip irrigation

Simple start-connector is used to connect the tape to the main pipeline. Its application accelerates the installation, allows you to create in just a few minutes sturdy durable connection. But it is better to buy an adapter with a crane. With it possible to adjust the pressure in each line, which precisely corresponds to that of the drip irrigation system.

The second - the intervals between the individual work cycles samopoliva from 6 hours to seven days. Next, click "Start" button. After this operation, the machine performs its functions without interference and control by the user. The manufacturer recommends to protect the equipment from moisture, use it only at positive temperatures.

To ensure an uninterrupted supply of water in the tank is mounted a simple float valve. It opens when the liquid falls below a certain level. If the container is connected to an artesian well, the wellOr another autonomous source, it sets the moisture sensor. Signals from it control the operation of the submersible pump.

This device is inserted into a pipe rupture in view of the working liquid movement direction. To avoid errors in the case there is an arrow. The master unit lowers the water main pressure to normal levels of irrigation systems in this category (maximum 1.4-1.5 atm). Built coarse mechanical filter retains impurities which can clog the outlet nozzles.

It should be emphasized that this is not set timer. It must be purchased separately. The manufacturer offers different models ranging in price from 3500 to 12 800 rubles.

This technique can be connected to the water mains with a pressure of 12 atm. Close visual display is set the time intervals, so the control is intuitive. Screen liquid crystal drive mechanisms and electronics perform their functions with a small power consumption. Size of a standard alkaline type batteries will last for a year of continuous operation. On the need to replace the special report alarm.

This modification differs enhanced functionality. In the standard version it is capable of independent control of four channels.

• Droplets of fluid delivery and provided fertilizer, so it is necessary to explore additional means for solving relevant problems.
• With the help of the photo is not difficult to understand how to create an irrigation system. But only in the project will be implemented during the action. For the corresponding experiments are also necessary to provide a stock of accessories.

Proper installation of drip irrigation

How to organize the installation of the system in the greenhouse will help to understand the following circuit.

Using this figure, you can learn how to correctly calculate the complete set. Will need the following items (in units) for the organization of uninterrupted workflow:

• valve with a metal tie-in a barrel for watering - 1;
• In-line filters – 1;
• Connector - 1;
• knee - 1;
• Tee - 1;
• plastic tube to create a backbone length of 25 m, diameter 32 mm;
• endcaps - 2;
• drip tape rolls 250 m - 2;
• start fittings - 30;
• taps fittings - 10;
• sealing gum - 40.

To start tapping connectors in the main pipeline need appropriate diameter drill, an electric drill.

Main pipes for drip irrigation

To learn about the diameter of the main pipeline need to select for irrigation suburban area (in a greenhouse), apply the formula D = 0.13 where:

• P - current flow of fluid into a cube. meters per hour, which moves along the corresponding portion of the main pipeline.
• Sd - liquid velocity (in these systems ranges from 0.5 to 1.5 meters per second).

Suppose that happened to 16 mm with rounding. Now we have to figure out how to choose the right product for summer irrigation. Even with the use of autonomous water supply systems should take into account the cost of its construction and operation. centralized utilities services have become more expensive every year. In studying the various options should be considered a significant financial loss, which creates a trickling hose.

it is necessary to pay attention to the following facts without giving exact prices:

• Of plastic pipes a lightweight durable design. Such products are not difficult to move. PVC pipes can be stored for long periods without special protection against water and damaging oxidative processes.
• Polyethylene pipes have a high elasticity. They are able to be deformed in a wide range without compromising the integrity of the product structure. These properties are useful for the creation of curved portions runs without corner fittings. HDPE pipe is not damaged by ultraviolet radiation, because it no additional protection can be installed in open areas.
• Similar advantages can be availed if you create a water main from polypropylene tubes. Their walls are not cracked in the bitter cold during the formation of ice inside the tubes.

  

• This technique allows to establish reliable seals for fittings, pipes, and other components.
• The system of plastic pipes has high durability. But drip irrigation such parameters are optional. Such products are harder to connect with their own hands. A significant limitation is the relatively high price. Drip hoses of this type may be damaged when the temperature drops below 0 ° C, if there is water therein.

If you need more precise adjustment, option is used for drip irrigation from bypass. How to choose the right product to help find the right account. To do this you must take into account the bandwidth injection level. All the necessary characteristics are shown in the data sheet for the product.

It is understood that the size of 1 inch assembly can provide lower performance than the product of 2 inches. It should be understood that the desired result can be achieved by increasing / reducing the pressure. Operational pressure correction may be performed by a pump, the main valves. Built gauges simplify control. In some models, set check valvesPreventing the penetration of water into the tank with chemicals.

Note! Due to the low cost of tinkering with his own hands, such a device does not make sense. Homemade injector is able to quickly break down, or become a source of contaminants in the system. Easier to buy a finished product created by a responsible manufacturer.

Filter for drip irrigation

These devices are used in gardening irrigation installations for coarse and fine purification from mechanical and other contaminants. In any case, the initial parameters have a value of the liquid, its degree of contamination and impurities composition. Given the price, product reviews and consumer characteristics are the following recommendations. They will help to know what type of filter to choose to equip a specific system:

• The strainer is used for mechanical retention of large particles. Efficiency depends on the mesh size.
• Set of disc elements performs a similar function. In this case, the liquid stream is moved by a more complex path, which improves cleaning.
• Gravel or sand filter can be done by hand. The purified raw material is poured into the desired size of the container. When improvised exact calculation device will not have poorer characteristics than the product known brand.
• Replacement cartridges are convenient for the user. Some models with carbon and other additives capable of retaining microorganisms, salts, and other chemical compounds.
• Cyclonic modifications are not suitable for drip systems. They apply for air cleaning from dust.

How to connect the filter, it is written in the accompanying documentation. As a rule, the arrow on the housing indicates the correct direction of motion of the liquid. There you can find information on how to clean up the contaminated item with your own hands.
