FIELD: agricultural amelioration, in particular, drop irrigation equipment. n SUBSTANCE: drop irrigation system has water source, pumping station, filters and irrigation network comprising irrigation pipelines with drippers. At least one irrigation pipeline with drippers is equipped with heads for fine dispersion spraying of water-solved macro- and microelements, herbicides, fungicides and acids. Heads are mounted on telescopic booms so that their position in vertical plane above soil surface may be altered. Each head is connected with irrigation pipeline through hose and T-piece. Head pitch on irrigation pipeline is 3-4 times greater than maximum radius of water spray discharged by head. Each head has diffuser made integral with casing, membrane of elastoplastic material, adjusting screw with needle at its end, and nut with rigidity rib disposed on casing. Membrane is positioned on needle of adjusting screw for joining with conical cavity of diffuser. n EFFECT: increased efficiency of drop irrigation system owing to providing comfortable conditions for plant development, and guaranteed yield. n 5 cl, 10 dwg |
