通过室内渗灌模拟试验,对低压毛管渗灌器在沙地土壤中水分入渗试验资料进行分析,结果表明:入渗率与入渗时间呈幂函数关系,而累积入渗量与入渗时间呈对数函数关系。湿润体近似于椭球体,并且水平扩散半径大于垂直入渗深度,椭球体的长轴在水平扩散方向左右对称,短轴在垂直入渗方向,上下不对称,且上短下长。

Based on the analysis of low-pressure capillary irrigation infiltration simulation test in sandy soil water,the results showed that infiltration rate and the infiltration of time showed the power function relationship,and the accumulated volume of infiltration and infiltration time was a function of the number.Moist body similar to ellipsoid,and the spread of the level of infiltration radius is greater than the vertical depth,ellipsoid level of proliferation in the long axis direction was symmetrical,in the short axis vertical infiltration direction,from top to bottom asymmetry,and short on the next chief.
