Abstract

The invention relates to the field of agriculture, in particular irrigated agriculture, and can be applied in the creation of reclamation systems for the cultivation of rice and associated crops. The purpose of the invention is to increase labor productivity, expand functionality and save water. The rice irrigation system contains a network of irrigation canals 2 and irrigation cards 5 suspended from them, each of which consists of checks 4, the width of which is equal to the capture of the sprinkler, and irrigation 3 is laid along the long adjacent side of the checks at the junction of four adjacent checks a water distribution node is installed, consisting of four irrigation and four discharge outlets, with a group discharge channel 6 across the cards, and in the middle of the checks parallel to the irrigator the drains 7, the mouth of which is connected to the group discharge channel by the shanzor regulators, and the source to the surface. The concentration of waste and water outlets and drain regulators in one route increases labor productivity, the location of the waste and irrigation network with intersection makes it possible to reuse water by adjusting the discharge. 3 il.

Description

The invention relates to agriculture, and relates to ameliorative systems for the cultivation of rice and related crops of the rice crop rotation.

The purpose of the invention is to increase labor productivity, expand the functionality of the system and save water.

Fig. 1 shows a rice irrigation system, in a glider in Fig. 2 a section A-A in Fig. 1, along a group discharge channel, in Fig. 3 a section B-B in Fig. 1, along a rice pad.

The system contains a water source 1 and an irrigation canal connected to it.

2, to which the card sprinklers 3 with two-sided command are suspended. Four equally sized checks 4 are suspended to the sprinkler 3. Sprinkler 3 and adjacent checks 4 form an irrigation section 5. A group discharge channel 6 is located along the adjacent sides of checks 4. There are closed drains 7 located in the middle of checks 4 node 8 consisting of pipe-crossing 9, waste check structures 10 and irrigation outlets 11. The drain 7 is closed at one end communicating with the observation well 12 connected to the group discharge channel 6.

The observation well 12 has a saddle regulator 13. The other end of the closed drain 7 is brought to the surface and closed by a protective cap 14, along the irrigator 3 and irrigation channel / 1 of the canal 2, roads 15 are moved along which the machine 16 moves, equipped with a pumping unit 17. The drawing system the contour of the vector-discharge channel 18 is connected with the water receiver 19. Sprinklers 3 are connected to the irrigation channel 2 through the downstream level regulator 20.

The system works as follows.

During the non-growing season, the drainage network is cleaned. For this purpose, a machine (tractor) is used, equipped with a pump and a water tank. The car alternately drives up to the protective caps 14 and blows the closed drain 7 from sludge and other particles. The drainage network is put in a free outflow mode, for which all wellhead hydraulic structures on the discharge network are opened. At the same time, a decrease in the level of groundwater over 1.5-2 m is achieved. In the spring, the soil is mechanically treated with checks 4 and the south and south of the country with sprouts. Aoda is fed to the irrigation network. The water level in the irrigators x 3 is maintained using downstream level controllers 20. The sprinkler 16, which takes water from the irrigator 3 pumping unit 17, moves along the road (15, irrigates the rice checks, maintaining soil moisture around 80 95% HB. After the emergence of seedlings and the formation of 2-3 leaf pfs, rice checks are flooded with water through irrigation outlets 11. If technological discharges are necessary, outlets 11 are closed and the discharge check structures are opened. After the tillering phase, the spindle regulator is lifted s 13 in the observation wells 12. In the period

Maintain water levels in checks; Watering is done by flooding checks. The sprinkler 16 at this time is installed at intersections

irrigation and waste channels and are used as pumping stations for pumping filtering water from group waste channels 6 to irrigators 3. After the rice ripens, the water from the checks is dropped

and diverted out of the rice system through drainage and waste channels 18 to the water receiver 19.

In the course of irrigation, the irrigator moves only along the road 15, laid along the kart drainage channel 6. Since all hydraulic structures are located at water distribution points 8, and the drainage wells are brought into observation wells located

along road 15, the irrigator travels along the shortest path, serving the maximum number of hydraulic structures. At the same time, labor productivity increases by 2–3 times.
