摘要
FIELD: agriculture.;SUBSTANCE: invention relates to agriculture, in particular to methods for heat-air melioration of subsoil layer of fields by year-round heating by means of solar radiation, and is intended for field crop cultivation. Method consists in using mole drainage. Beginning of molehills 1 is located in one furrow, and the end – in the other furrow. Walls and dump of soil of furrows are located from the side of the sun. From one end of molehills 1 in suction pipe there installed is suction branch pipe with heat-air temperature valve, covered with translucent screen, and at the other end – an exhaust pipe covered with a light-permeable screen with an inclined pipe having air passage holes and a vertical pipe. Branch pipe is tightly connected to molehills 1, and its outlet is located above the screen and equipped with a deflector.;EFFECT: method will make it possible to provide all-year heat-air heating of subsoil layer of fields, as well as temperature control of subsoil layer depending on need for heat of plants, which will increase crop capacity with minimum operating costs.;6 cl, 7 dwg
