【Abstract】 In this paper, the relationship between infiltration velocity and infillration coefficient, infiltration index is obtained by infiltration experiment through surface membrane crack. The superiority of irrigation through membrane crack and the technical targets under the conditions of separate unit discharge and separate sealing factor are analyzed. The technical parameters of irrigation of higher uniform degree and utilization ratio and uniformly distributed infiltration water are determined to provide the technical instruction for popularization of irrigation technique through membrane crack in irrigation area.更多还原
