METHOD OF IRRIGATION OF FRUIT TREES AND SHRUBS ON THE SLOPES OF RAVINE Russian patent published in 2019 - IPC A01G25/00 A01G25/06 

FIELD: irrigation.

SUBSTANCE: invention relates to hydrotechnical melioration and can be used in drip irrigation on slopes. When implementing method of irrigation of fruit trees and bushes on ravine slopes water source, water conduit, water distribution units, distributing and irrigation pipelines, water-measuring equipment, device for mixing and dosing fertilizers and water intake are used. Water source is equipped with a pump. Pump is hydraulically connected by pressure water conduit with reserve water tank. Water discharge branch pipes are connected to distributing pipeline in water distribution units. In end part of branch pipes there installed are water receivers with reservoirs. Reservoir comprises inlet and outlet holes and housing arranged in vessel. Housing in lower part is equipped with equalizing chamber with float in the form of biconvex lens. Outlet branch pipe of the case is fixed by means of threaded connection with the equalizing chamber case. Lower part of the chamber is connected to an additional outlet branch pipe and to an irrigation pipeline with droppers. Float with shutoff elements is installed in the body. Body and float are spherical. Locking elements are made in the form of conical needles. Inlet and outlet branch pipes have conical sockets. Shutoff socket of inlet branch pipe is located in container. Shutoff socket of outlet connection pipe is coaxially connected with equalizing chamber. Container is additionally connected with the balancing chamber by means of tubular channels. Channels are connected with side holes in walls of outlet branch pipe. Lower end of the body is rigidly attached to the vessel bottom. Housing is detachable. Distributing pipeline is laid on surface of the earth along slope of slope ravine. Irrigation pipelines are laid on the terrace. Top of the droppers from the branch pipes is placed above the ground surface. Drippers are made of corrosion-resistant polymer material.

EFFECT: simple operation of the irrigation system, high quality of irrigation and uniformity of irrigation water consumption, as well as higher yield of fruit trees and bushes.
