膜孔灌的基本原理初探

A Preliminary Study on the Basic Principle of the Membrane Hole Irrigation

简要叙述了当前地膜种植的一般灌水方法和存在问题；提出了膜孔灌及其灌水技术的新概念，进而得出了膜孔灌灌水强度和均匀灌水原理的数学表达式；解决了地面灌不易解决的难题——提高灌水均匀度和延伸灌水长度的矛盾。为实现现代灌溉农业节水、高产、优质、高效总目标奠定了灌水技术的理论基础。

The general irrigation methods and existing problems of ground membrane planting have been explained briefly. A new concept of the membrane hole irrigation and it's technology is presented. Furthermore,a mathematical equation of irrigation intensity and uniformity of the menbrane hole irrigation has also been abtained and the conflict of irrigation uniformity and extending length is solved. The theoretical basis of irrigation technology for carrying out the general goal of agricultural water--saving, high yield, quality and efficiency is set.[
