Drip irrigation: what is it
Drip irrigation can be used for a variety of plants that grow outdoors in a greenhouse. Water can come from a well using a pump, from a water supply system, or from a barrel. The water supply can be carried out under the influence of gravity or forced. In the first case, the liquid comes from the tank according to the law of gravity.
Then the device must be located on a slope. In the second case, water is supplied from a pump connected to the well.
To create the required pressure in the gravity system, the tank must be at a height of at least 2 meters. Water flows through pipes and their branches. A drip tape runs from them along the rows of plants. As a result, water is distributed over the required area. The water supply can be adjusted at a strictly allotted time, even when there are no owners on the site.
Advantages of drip irrigation
The drip irrigation system not only solves the problem of supplying plants with moisture, but also saves the owner's time. The main advantages of this type of watering of plants:
- No need to heat water
- Irrigation uniformity
- Possibility of saving water
- Reducing the appearance of weeds
- Water supply regulation
- The ability to use several modes of irrigation
- Several activities can be combined
- Use of salt water
With this method of watering, the roots of the plant will never lack moisture. The system controls the strength and volume of the water supply. In addition, a hard crust does not form on the surface and there is no erosion of the fertile layer, which is often observed with manual irrigation. There is no need to be afraid that moisture will get on the leaves.
Water flows directly under the root. Together with watering, vegetable crops are fed. At the same time, you can accurately adjust the dosage of mineral fertilizers. In addition, drip irrigation ensures air-water balance. This means that the air in the soil is retained, which cannot be said about the surface irrigation method.
This method can be used on any soil, even highly compacted, where there is a low rate of water penetration. Windy weather does not interfere with the quality distribution of water to the roots of plants. A ready-made drip irrigation system is not cheap, but you can make it yourself if you have the technical skills.
Materials and tools for work
Before you start installing the system, you need to design relative to your site. If the suburban area is small, then the distance between the droppers on the drip tape should be 25-35 cm. It is necessary to correctly calculate the length of the tape and the capacity of the tank. Only in this case can the optimal irrigation regime be achieved.
To calculate the volume of the tank, you should take the area of the territory. About 30 liters of water will be needed per square meter, which means if the plot is 25 m2, then the volume of the tank should be 700 liters. To install the drip irrigation system, you need to prepare the following materials:
- Tank or pump
- Pressure reducer
- Valve and ball valve
- Filter for cleaning
- Plastic pipes with a cross section of 16-20 mm
- Drip tape and adapter to it
It is better to use rigid plastic pipes for water supply, and flexible hoses are better for distributing in beds. Of the tools for installing a drip irrigation system you will need:
- Adjustable wrenches
- Hole puncher
- Pipe cutters
After purchasing all the necessary materials, you can start making the system.
Step-by-step instructions for the device: basic steps
On the diagram, it is necessary to mark the place where the water tank will be located, as well as the main hose. It is necessary to measure the length of the beds and the distance between the vegetable crops. This is necessary in order to correctly calculate the length of the hose and the gap between the droppers. After all the calculations have been made, you can proceed directly to the installation.
The main stages of creating a drip system
Install the container at a height of 1.5-2 meters. Drill holes in the hose at a certain distance according to the drawing. First, you need to apply marks for attaching drip tapes. Next, attach drip tapes to the pipe using starter fittings. The diameter of the holes must be of such a size that the seals are forced into place.
Then the start connector is inserted into the seal. It comes with a tap. Connect the main hose to the drum. In order for the water to be cleaned, you need to install a filter between the pipe and the tank. Drip tapes are run along the beds. Close one end with a plug, and connect the other to the main pipe.
Cut the feed pipe just above the bottom of the barrel. This is done to prevent debris from entering the system and settling to the bottom. During water supply, the hose may move to the side. To prevent this, the watering hoses are secured with staples. At the final stage, fill the container with water and turn on the system. If you plan to irrigate several beds, then you need to connect tees. In this way, several supply pipes are connected into a common system.
Irrigation using plastic bottles
Drip irrigation can be made from plastic bottles. This method is convenient to use if the owners periodically come to their summer cottage. Uniform watering is carried out within 2-4 days.
Installation of drip irrigation using bottles:
- Cut off the bottom of the container and make several holes on both sides.
- Next, bury a bottle between two bushes of plants. In this case, the bottom should be located on top.
- Pour water into the container. Moisture will seep through the holes.
- When the ground starts to get wet, the holes are clogged. After the soil dries up, the holes open and the liquid flows back to the plants.
Plants will not accept excess moisture. When the water in the container runs out, it is topped up. This option is usually used to irrigate small areas. There is another way of watering - by hanging a container of water on a wire.
In this case, holes are made at the bottom of the bottle or in a twisted cork. This method can also be used for feeding vegetable crops using liquid fertilizers. You can build a drip irrigation system with your own hands, significantly save money and make your job easier.
