| 摘 要： | 以室内试验为基础，测定了重壤土、中壤土、砂壤土在不同滴头流量、不同灌水量下的点源人渗运动过程，通过对点源人渗特性的单因子分析表明，湿润锋水平、垂直扩散距离不仅与滴头流量、灌水量关系密切，与土壤特性(土壤容重、初始含水率)也存在良好的幂函数关系，得出了以土壤物理参数和湿润比及湿润深度为基础的点源滴灌滴头流量的设计模式。

| Abstract: | Based on experiments,the movement of the wetting front was studied in clay-loam,loam,and in sandy soil under different dripper discharge and drop water.By mono-factor analysis of the point drip infiltration,the horizontal and vertical movement distance of soil wetting front were not only in close relation with dripper discharge and drop water,but also had good power functional relation which exists with the soil characteristic (soil density,soil initial moisture).It draws dropper discharge design mode for point source drip irrigation based on soil physical parameter and wetted front rate and wetted depth.The result of study has certain guidance functions to the systematic design theory of drip irrigation. |
