Single-Hole Water Distribution of Polyethylene-Blankholder Spray Tape
Abstract：As a new water-saving irrigation system,the polyethylene-blankholder spray tape was concerned in this paper.Aiming for better design,producing and applying the pioneer product,reasonable arrangement of spray holes was studied and the effects of working pressure(0.1 MPa and 0.15 MPa),spraying angle(43°,65°,and 79°),and spraying hole diameter(0.5 mm,0.6 mm,and 0.7 mm) on water distribution of the polyethylene-blankholder spray tape were researched.The results showed that the width of dry zone,and the length and area of wetting zone were mainly affected by spraying angle,and decreased with the angle increase;the width of wetting zone,which ranged from 0.25 m to 0.50 m,was kept relatively steady though it had an increasing trend with spraying angle at 0.15 MPa;average irrigation intensity increased as working pressure,spraying angle,and spraying hole diameter increased,and especially,it was more sensitive to spraying hole.
