LOCAL SUBSURFACE IRRIGATION SYSTEM FOR PERENNIAL PLANTATIONS Russian patent published in 2022 - IPC A01G25/06 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. The system contains a water source, distribution and irrigation irrigation pipelines, humidifiers, water-measuring equipment, a pumping station, hydraulically connected by a pressure pipeline with a hydraulic feeder, distribution and irrigation pipelines. Distribution and irrigation pipelines are located on the soil surface with plugs at the ends. Along the entire length of the irrigation pipelines, flexible microtubes with a pitch of 3000-4000 mm are mounted, connected to subsurface humidifiers, made of corrugated with an external one-sided perforation up to 3.5 mm in diameter with a pitch of 150 mm along the entire length and laid in a circle of the planting hole to a depth of 40- 50 cm. The system is additionally equipped with a device for the preparation of irrigation water, including a hydrocyclone, a block of disc and mesh filters.

EFFECT: invention provides directed uniform local distribution of moisture in the root layer of the soil, equalization of pressure and normalization of pressure in the system of local subsurface irrigation of perennial plantations.
