本文从地膜栽培给灌水带来的新问题出发,揭示了当前地膜种植的几种主要灌水方法存在的问题,然后根据现代灌溉农业对灌水技术的要求,得出提高灌水均匀度和延伸灌水长度是当今世界灌水方法和灌水技术研究的主攻方向,据此设计了膜孔灌水方法。不仅解决了当前地膜栽培中存在的膜下灌水不足、膜问露地灌水有余和上游灌水有余、下游灌水不足问题,同时又能满足现代灌溉农业节水、高产、优质、高效的要求。所以说膜孔灌是地膜种植的科学灌水方法。
Based on the new problems brought by film mulching irrigation, the problems of several main irrigation methods of mulching film were revealed. Then according to the requirements of modern irrigation agriculture for irrigation technology, it is concluded that increasing irrigation uniformity and extending irrigation length are Nowadays, the main direction of research on irrigation methods and irrigation technologies in the world has been to design a method of film hole irrigation. The present invention not only solves the problem of insufficient irrigation under the membrane in the current film cultivation, but also has the problems of inadequate irrigation in the open field and inadequate irrigation in the upstream and insufficient irrigation in the downstream. Meanwhile, the invention can meet the requirements of water saving, high yield, high quality and high efficiency in modern irrigated agriculture. So film hole irrigation is a scientific method of planting plastic irrigation.
