Sprayers are fixed on drain parts of flat tools arranged in the vicinity of plant row and adapted for directed feeding of herbicides and fertilizers to plant root system zone. Sprayers are provided within flexible wear-resistant hose on its lateral side directed toward plant row axis. During operation of unit, hose rests upon soil surface to follow its relief and feed liquid to plant root system zone. Spraying apertures are formed conical. ^ EFFECT: increased yield owing to effective weed elimination, reduced power consumption and increased efficiency of unit. ^ 3 cl, 4 dwg |
