METHOD FOR OPERATING PLANT GROWING UNITS IN GREENHOUSE WITH TRANSPARENT GUARD Russian patent published in 1998 - IPC

FIELD: agriculture, in particular, growing of plants in hydroponic greenhouses. SUBSTANCE: method involves regulating angle between cross bars 4 of carcasses of hydroponic units 3 carrying plant growing containers 6, with cross bars being pivotally connected with their upper parts. Angle regulating process involves folding cross bars 4 of each hydroponic unit 3 prior to period, when natural radiation intensity increases; connecting upper parts of two adjacent units 3 while arranging their lower parts at distance of (1-2)L, where L is distance between lower parts of cross bars 4 of adjacent units 3 before folding process; returning cross bars 4 of units 3 to the initial position upon termination of mentioned period. Method allows plant yield to be increased by 8-11%. EFFECT: simplified method and increased efficiency by rational usage of natural radiation and improved yield. 2 dwg
