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。
Field irrigation of membrane holes is a point source three-dimensional human seepage problem under the condition of adequate water supply. According to the systematic indoor experiment on point source infiltration, a point source model is established, which contains many factors such as membrane hole diameter, soil texture and soil initial water content. The tested model has certain fitting precision The research laid the foundation for the further study of membrane irrigation theory and irrigation technology.
