METHOD OF CULTIVATION OF VEGETABLE CROPS UNDER DRIP IRRIGATION Russian patent published in 2014 - IPC A01G1/00 A01B79/02 A01G25/02 

FIELD: agriculture.

SUBSTANCE: method comprises the layout of irrigation piping, transplanting the agricultural crops in points of placement of water outlets and vegetative irrigations. Irrigation piping layout is carried out with a unit for transplanting and laying the irrigation piping, equipped with a drum with irrigation piping placed on it, the length of which should correspond to the distance between the headlands of the irrigated field. For vegetative irrigation the drip irrigation system is used, comprising the water source, the unit of water purification from impurities and electric actuator connected hydraulically through locking and regulating device with distribution manifold having drain pipes for connection of irrigation pipelines. The distribution pipe is placed at the front edge of the headland of the irrigated field. The electric actuator of water is equipped with DC generator with adjustable parameters and switch potential, the activating part of the electric actuator of water comprises a cylindrical housing made of stainless steel or titanium with threaded tips, and performing the function of the outer electrode. In the inner cavity of the cylindrical housing separated by a semipermeable diaphragm microporous plastic, the internal electrode is mounted with the possibility of mounting and dismantling, formed of undulated plates of stainless steel, mounted in the inner cavity of the housing crosswise. The distance between the plates is taken from the condition to ensure the necessary flow passage section, providing the desired flow rate through the electric actuator. Supply of electric potential to the inner electrode is performed through the terminal insulated from the housing by the dielectric sleeve, and the supply of potential to the housing is performed through the terminal fixed to the housing outer surface. The vegetative irrigations are carried out in the following sequence: first irrigation with catholyte with the potential -300÷-400 mV at pH of 7.5-8 and the rate of irrigation of 2-3 litres per the plant. After a day the irrigation with the anolyte is carried out - electric actuated water with potential +500÷+600 mV with bringing soil moisture to the minimum field capacity (MFC). Then, irrigation is carried out periodically to maintain soil moisture within 80-85% of the MFC with the catholyte with the potential -200÷-300 mV. Irrigation with anolyte with a potential of +600÷+700 mV is carried out at the appearance of pathogens or pests with bringing soil moisture within 80-85% of the MFC. After harvesting laying the irrigation piping on drums is carried out from the front hitch device of the tractor, provided with brackets for hinging the drums.

EFFECT: method enables to increase productivity and reduce labour intensity of cultivation.
