FIELD: agriculture. SUBSTANCE: irrigation system has plot distributor, irrigating devices, through irrigation furrows, catch basin, collector for drainage and rain water. For irrigating continuously sown farm crops on sloped plot with gradient of 0.004-0.007, width of furrow bottom is provided within the range of from 0.13 m to 0.15 m. Width of furrow top part is from 0.23 m to 0.25 m, depth of furrow is from 0.10 m to 0.12 m and width of furrow spacing is 0.6 m. Irrigation furrows on plot with gradient i less than 0.004 have bottom width of from 0.23 m to 0.25 m, top width thereof is from 0.33 m to 0.35 m, depth from 0.09 m to 0.11 m, furrow spacing is 0.90 m. Irrigating flow horizon may be above furrow ridge within the range of 0.02-0.03 m. EFFECT: increased efficiency by uniform moistening of root system of narrow-row crops, in particular, at initial stage of development. 2 dwg
