METHOD FOR DRIP IRRIGATION OF PERENNIAL PLANTATIONS OF SLOPE LANDS Russian patent published in 2020 - IPC A01G25/02 A01G25/16 A01G17/00 

FIELD: land reclamation.

SUBSTANCE: invention relates to the field of land reclamation on sloping lands. Method involves drip irrigation of perennial plantations of slope lands arranged on a distributing pipeline with inclusion of a discharge tube or a hose connected through a tee-piece, and an annular unclosed drainage system with droppers placed on it. Each open drainage system in places of removal from discharge watering tube is made in form of vertical rigid plastic riser connected to unclosed flexible irrigation plastic rigid tube, ends of which are equipped with short rigid corrosion resistant adapter fittings made of polymer material with possibility of fixation of each of them by means of fixed clamps arranged on external surface of put ends of non-closed flexible irrigation plastic rigid tube. At that free ends of short rigid fitting-adapters are interconnected by means of corrugated elastic couplings with yokes. Each watering plastic rigid tube is additionally fixed by female hinges on its surface with rods also from rigid polymer material with attached tightening detachable power belt with a latch of wear-resistant plastic material at its attachment height with possibility of embracing the tree bole. At that, each irrigation rigid plastic tube has holes, on the surface of the tube the resiliently strong elements in the form of put pipes of the same length are placed with the covering end, which inner part is equipped with tubular porous material, providing possibility of flow and water flow braking with equal speed through ends of put pipes with drip irrigation. Each vertical rigid riser connected to deflecting irrigation tube is equipped with adjusting ball valve.

EFFECT: method provides for top-down humidification of woody plants and automatic release of inter-stratum space on the ground upon completion of watering and unobstructed performance of works in inter-stratum space during inter-irrigation period.
