摘要
随着膜下滴灌技术在新疆的大力推广应用,灌排模式发生了改变,从而导致了新的土壤次生盐渍化问题。在阐述新疆3种排水措施——明沟排水、暗管排水和竖井排灌发展的基础上,分析了目前新疆节水灌区农田排水措施存在的问题,结合南疆某一节水灌区灌排试验,分析了排水措施对土壤盐分及地下水位、矿化度的影响,为当地灌排模式提出合理化建议,且为减轻节水灌区的土壤盐渍化提供参考借鉴。
With drip irrigation technology in large scale, changed the irrigation and drainage pattern, which leads to the new problem of soil salinization. This paper describes the development of Xinjiang drainage measures ditch drainage, subsurface pipe drainage and vertical drainage, and analysis of the problems of drainage measures in Xinjiang water-saving irrigation area the current and the effects of drainage on soil salt content and groundwater level. And it combines with the irrigation and drainage test in Xinjiang reservoir downstream water-saving irrigation area, put forward reasonable suggestions to the local drainage measures and provide a reference for water-saving irrigation area to reduce soil salinization.
