论膜下滴灌技术在干旱-半干旱地区节水抑盐灌溉中的应用

A Breakthrough Thought for Water Saving and Salinity Control in Arid and Semi-arid Area— Under-film trickle irrigation

以干旱 -半干旱的新疆地区为重点 ,分析了传统盐碱地开发改良的缺陷与不足 ,提出了干旱 -半干旱地区盐碱地开发与改良的新思路 -膜下滴灌技术。膜下滴灌集地膜覆盖与滴灌的优点于一体 ,对土壤的水、盐、热状况有良好的调节作用。膜下滴灌在西北地区已有应用 ,经生产实践证明有良好的节水、洗盐和生产效益。

Focusing on Xinjiang, a arid and semi arid area, disadvantages and shortcomings of traditional saline soil development and reclamation were analyzed. A breakthrough thought for water saving and salinity control in arid and semi arid area, i.e. under film trickle irrigation, was presented. The advantages in both plastics film mulch and trickle irrigation was integrated in under film trickle irrigation system. The wide application of this irrigation system in northwestern areas has shown that under film trickle irrigation is helpful to improve water use efficiency, to control salinity and to raise yield.
