FURROW IRRIGATION SYSTEM Russian patent published in 2002 - IPC

FIELD: agriculture. SUBSTANCE: irrigation system has stationary irrigator. Designed slope coefficient m of channel is 4-10, width of bottom is 1-4 m, lengthwise slope is 0.0005-0.00015. Stationary fuel pipes of 4-6 cm diameter and 5-10 m length are mounted inside irrigator dam level with mark. Dam ridges are arranged in single horizontal plane to provide for depth in irrigator within the range of 20-30 cm at water flow rate 0.10-0.15 cu.m/s. System of such construction allows irrigator labor intensity to be reduced. EFFECT: elimination of labor-consuming expensive manual works for mounting of hollow pipes and dismantling thereof before crop harvesting and provision for yield retention. 2 cl, 3 dwg
