agriculture. SUBSTANCE: method involves invoking electrostatic field above the plants by means of radiators receiving power from high voltage current supply source. The radiators are designed as strings arranged in the same horizontal plane above the plants. Constant current of positive polarity is supplied to the strings under +1770 to +4500 V potential from the high voltage current supply source during light part of the day. EFFECT: easiness in operation; useable in industrial greenhouses and personal household. 3 cl, 5 tbl _ |
