FIELD: agriculture.
SUBSTANCE: system comprises longitudinal and transverse toothed strips mounted orthogonally to each other by means of slots located on trapezoidal protrusions of toothed strips, zigzag pipe of rectangular profile includes upper and lower trapezoidal projections and mounted between longitudinal toothed strips symmetrically relative to axis of symmetry of trapezoidal cuts of transverse strips. Lower walls, side and end walls of lower trapezoidal protrusions of zigzag pipe form trapezoidal volumes for accumulation of liquid, located at intervals with the same pitch. On side walls of trapezoidal volumes for accumulation of liquid there are holes of the same diameter for liquid supply. To side walls of trapezoidal volumes for accumulation of liquid on mutually opposite sides are adjacent longitudinal adjusting toothed strips containing holes coinciding with holes on side walls of trapezoidal volumes for liquid accumulation. In the inner cavity of the zigzag pipe along its entire length there is an adjusting strip-rod made with holes for supplying liquid to trapezoidal volumes for liquid accumulation.
EFFECT: higher quality of the system is ensured by improving reliability, uniform distribution of irrigation liquid and reduced consumption of irrigation liquid.
