Abstract

This invention relates to agriculture. The purpose of the invention is to save irrigation water and increase the yield by creating a favorable water-air regime in the root zone. In the system, the check water supply shch and the discharge channels 9 for two rows of checks are made in the form of a single insulated at the ends, dipped and lined tray with combined irrigation and draining functions. Along the length, the channel 9 is lined with a coating and an underlying filter gravel layer 14 associated with sipe-like gravel drains crossing either side of the check channel 9 crossing the check area. At the bottom of the check channel 9, there are located perforated pipes 16 filled with gravel, made in the form of vertically located women and communicated with the gravel bedding layer of the filter head. The check channel 9 communicates with the checks by free inclined pipe outlets 17, and the ends of it are connected to the distributor by the water supply channel 4 on one side, and to the outlet channel on the other side by means of pipelines on which level control automatic hydraulic machines 18 are installed. 4 il. but;

in direct station 3.

Rice irrigation system works as follows.

When rice is cultivated, if necessary, it is necessary to check the pre- or post-seeding soil moisture in checks 1 pump station 3 delivers irrigation water under pressure to closed water supply (card) pipelines 4, from which water passes through hydraulic machine 20 into check channel 9. Hydro-machine 18 the outlet network is closed. At the same time, the water level in the channel 9 is kept constant by means of a hydro-automatic machine 20. Under the action of a nano-device created in channel 9 through pipes 16, water passes through layer 14 into drains 15 and then rises using the soil polarity up to its surface. Reduced water level in channel 9 can automatically reduce the level of moisture in the feed bed.

In the phase of the exit of rice into the tube, previously dropping moisture through the gravel drain 15, passing through the plane of the check, the rice is weeded against weeds and fertilizers are applied.

After completing measures to control weedy vegetation and fertilization (if necessary), the water level in the check channel 9 is installed with a hydroautomatic machine 20 at a level that should ensure the level of marginal moisture capacity.

For 8-10 days before the rice is harvested, the level of the subsoil water in check 1 is dropped through the system of slits-drains 15 to the mark, which allows preparing the system for rice harvesting.

During harvesting, the irrigation system can perform the functions of draining and lowering groundwater. At the same time, the hydraulic automatic machines 20 are closed and the hydraulic automatic machines 18 are opened. The groundwater, for example, due to infiltration and its own weight, accumulates in the gravel slots-drains 15, rolls through the filtering layer 14, the branch pipes 16 and the receipt channel and then through the discharge is transported into the discharge channel 5 and further into the reservoir pool 7.
