METHOD OF AND DEVICE FOR GROWING PLANTS Russian patent published in 1996 - IPC

FIELD: agriculture. SUBSTANCE: plants are placed in t-pieces horizontally connected to each other. Plants in upper parts of t-pieces are fixed by means of plugs and cups. Nutrient solution is delivered periodically into vegetative system by means of master switch which closes electric circuit, simultaneously switching on pump and emergency automatic nonreturn electromagnetic valve. Nutrient solution gets into reservoir for solution. Valve shuts off delivery of liquid into vegetative system. Plants are held without solution for 4-5 min at air temperature in greenhouse equal to 25-27 degrees C. Then master switch breaks electric circuit, and valve feeds nutrient solution to vegetative system. EFFECT: prevention of root rotting, provision of uniform saturation of vegetative system with nutrient solution. 2 cl, 3 dwg, 1 tbl
