PROTECTIVE COMPLEX FOR PLANTS Russian patent published in 2006 - IPC A01G9/24 E04H5/08 

FIELD: agriculture, in particular, protective complexes for plants, including greenhouses and hothouses equipped with electrotechnical and other equipment for care of plants and heat-loving bushes grown under home conditions or small-scale commercial plant growing conditions.

SUBSTANCE: protective complex has foundation pit with supporting carcass onto which transparent protective casing is put. Plastic walls of foundation pit are slightly extending beyond base of supporting carcass and are secured by means of drop screen. Foundation pit bed has ground provided with thermal layer and soil heating members. Foundation pit bed is connected through pipe to suspended closed reservoir hung under complex roof to define, in conjunction with foundation pit construction filled with ground and top layer of fertile soil, single reservoir with water influx-discharge regulated by means of electronic valves provided on branches as well as on pipe. Water is pumped through lower branch by means of water pump into suspension reservoir, and other branch equipped with electronic valve defines closed semicircle on pipe. Such construction provides water discharge by avoiding first branch from suspended reservoir into pipe equipped with corrugated insert provided at its lower end. Level of discharged water is controlled through bushing equipped with float having water level measuring ruler. Supporting carcass incorporates thermal sensors, humidity sensors, illumination sensors, air heating members, and illumination lamps. Valves are opened and closed by means of electronic device. All parts of protective complex are totally controlled by electronic instrument for maintaining optimal microclimate mode. On the basis of electronic instruments and with the use of communicating vessels principle, protective complex may be created, wherein, apart from setting optimal water level in ground soil and irrigation time, optimal heating and illumination mode may be maintained to thereby regulate plant development. Protective complex allows vegetable and other crops, as well as wild and exotic plants to be grown.

EFFECT: increased yield of vegetables and other crops.
