SYSTEM OF LOCAL-SUBSURFACE IRRIGATION OF A GARDEN ON SLOPING LANDS Russian patent published in 2023 - IPC A01G25/02 

FIELD: agriculture.

SUBSTANCE: system comprises a water source, water distribution pipelines and irrigation pipelines connected to them with drip water outlets in the form of microtubes associated with humidifiers in the form of perforated containers. Irrigation pipelines are connected to the water distribution pipeline through pressure regulators and placed along the slope horizontal lines. Each humidifier is made in the form of a piece of perforated pipe of oval cross-section with a conical cover equipped with a hole in the middle part and two bushings symmetrically mounted into its walls. On top, the cover is equipped with a horizontal strip with two holes, coaxial with the holes in the cover bushings, and a hole for a microtube with a lock for its position. Inside each humidifier there is an oval disk with an elastic seal around the perimeter with a diameter corresponding to the internal diameter of the humidifier. The disk is equipped with two rods with measuring divisions, brought up through coaxial holes in the bushings and the bar, where their position clamps are installed. The humidifiers are located with a small oval diameter parallel to the horizontal slope.

EFFECT: moistening of the root zone of trees is ensured, taking into account the capillary properties of the soil and the depth of placement of the root system of the tree in different parts of the slope without shifting the moisture circuit beyond the zone where the tree roots are located.
