| 摘 要： | 膜孔灌溉的田面人渗属于充分供水条件下的点源三维人渗问题。根据对点源人渗所做的系统室内试验研究,建立了包含有膜孔直径、土壤质地及土壤初始含水量等多因子的点源人渗模型,经检验模型具有一定的拟合精度,从而为膜孔灌溉理论与灌水技术要素的深入研究奠定了基础。

| Abstract: | In filmed hole irrigation,the infiltration from a field surface can be modeled as a 3-D Infiltration from a point source with sufficient water supply.In this paper,based on a series of experiments,a point source infiltration model which includes the effects of the hole diameter,the soil texture,and the initial soil moisture,etc.is developed.The accuracy of the model is satisfactory.The results would greatly benefit the stufy on the filmed hole irrigation theory and the irrigation technology. |

| Keywords: | Film hole irrigation Infiltration from a point source cumulative infiltration |
