本文选择国内外普遍使用的以色列内螺纹式和国内利用其技术制造的管上式、内镶式滴灌管、软滴灌带及针孔式渗灌管 (运城模式 )为研究对象 ,对它们的出流量及均匀性进行了大量试验 ,并对针孔式进行了改变孔径试验 ,得出如下结论 :(1 )滴头出流量与压力的关系曲线 ;(2 )内螺纹式、内镶式、管上式出流均匀性最好 (>98% ) ,软滴灌带次之 (≈ 91 % ) ,针孔式最差 (<87% ) ;(3)针孔式均匀性随滴头孔径增大而大幅下降 ,针孔式 ( 2mm)基本不能满足生产使用 In this paper, the commonly used Israeli domestic and foreign thread type and the domestic use of its technology to make the tube type, inlaid drip irrigation, soft drip irrigation and pinhole (Yuncheng mode) as the research object, their output Flow and uniformity of a large number of experiments, and the pinhole to change the aperture test, draw the following conclusions: (1) drip flow and pressure curve; (2) (> 98%), soft drip irrigation followed (≈ 91%), pinhole worst (<87%); (3) Pinhole uniformity increased with dripper aperture The sharp decline in pinhole (2mm) basically can not meet the production and use
