СПОСОБ ПОЛИВА И МАШИНА ДЛЯ ЕГО ОСУЩЕСТВЛЕНИЯ

摘要

FIELD: agriculture. ^ SUBSTANCE: method involves locating water outlets with heads in equally spaced relation along radius with equal flow rate characterized by and equal to flow rate of water outlet outer from center; creating pulsed operation mode for water outlets by width-pulsed or frequency-pulsed controlling; setting and tuning ratio of periodic irrigation time tui for each of water outlets with heads to irrigation time tui and lack of irrigation Tni with ratio of ordinal number i of water outlet from center to total quantity n of water outlets in accordance with dependence: Each of water outlets uniformly positioned on water pipeline is equipped with valve connected to control device or pulse generator with adjustable switch-on and switch-off time during periodic operation thereof for regulation of time-pulsed and width-pulsed controlling, which are individually adjusted for each valve depending on its ordinal arrangement on water pipeline and total quantity of water outlets thereon. Heads for sprinkling, surface irrigation and circular irrigation are mounted at valve outlet ends. ^ EFFECT: improved quality of irrigation and simplified construction of irrigation machine. ^ 3 cl, 2 dwg
