FIELD: agriculture.

SUBSTANCE: group of inventions relates to agriculture. Device for intrasoil treatment, tillage, aeration and supply of agrochemicals to rice crops includes: bearing frame (1), on which lifting pneumatic cylinders (2) and adjustable supports (3) with wheels (4) are installed, electric power source (5) with electric drive (6), compressor (7) with compressed air receiver (8), pump (10), tanks (11) with agrochemicals, guide ring (12) and working frame (14), frame elements (21), hoses (29), pressure regulator-stabilizer (9), which connects compressed air receiver (8) through the corresponding electric pneumatic valves with pneumatic cylinders (26) and pneumatic hydraulic drills (27). Working frame (14) is equipped with guides (18), on each of which there are working pneumatic cylinders (26) with pneumatic hydraulic drill (27) attached to them from below. Working pneumatic cylinders (26) are connected to each other with possibility of synchronous horizontal movement. At the centre of each frame element (21), distributor-stabilizer (28) is installed, which is connected by hoses (29) to compressed air receiver (8) through each working electropneumatic valve with each working pneumatic cylinder (26), through each additional working electric pneumatic valve with each pneumatic hydraulic drill (27), and through each agrochemical pneumatic valve each pneumatic hydraulic drill (27) is connected to pump (10) and tanks (11) of agrochemicals. Each lifting pneumatic cylinder (2) is connected by hose (29) through lifting electrically driven pneumatic valve (32) to compressed air receiver (8). Method of intrasoil treatment, tillage, aeration and supply of agrochemicals to rice crops is carried out by compressed air pulses by vertical immersion into soil of pneumatic hydrodrills (27). Pneumatic hydraulic drills (27) are immersed in soil and interact with it, creating traction force, which moves working frame (14) and the whole device along row spacing of rice. At the same time each working pneumatic cylinder (26), having reached the switch, opens the working electropneumatic valve, and through hose (29) compressed air is supplied to working pneumatic cylinder (26), which immerses pneumatic hydraulic drill (27) into the soil. When each pneumatic hydraulic drill (27) reaches the lower working position, the additional working electropneumatic valve via hose (29) through distributor-stabilizer (28) supplies compressed air pulses, which perform soil tillage and aeration. Agrochemicals are then fed through each agrochemical electropneumatic valve via appropriate hoses (29). When each working pneumatic cylinder (26) reaches the switch, working electric pneumatic valves stop supply of compressed air and agrochemical pulses. Pneumatic hydraulic drill (27) and corresponding working pneumatic cylinder (26) lifts and extracts this pneumatic hydraulic drill (27) from soil. Upon reaching the edge of the paddy field, the device is stopped, simultaneously the working electric pneumatic valves close the supply of compressed air and agrochemicals to pneumatic hydraulic drills (27), and pneumatic cylinders (26) lift them above the water surface.

EFFECT: increased productivity of root inhabited soil layers in rice crops flooded with water, ensuring achievement of maximum biological and ecological parameters of soil with high quality, mobility, energy efficiency of the technological process due to tillage of soil and delivery of air (aeration), microbial biopreparations, fertilizers, plant protection agents and weed control agents directly to the root system of rice plants.
