暗管排盐关键技术的研究进展

Research Advance of Covered Pipe Salt Draining Key Technology

土壤盐碱化和次生盐碱化是一个世界性难题,如何有效治理盐碱地成为近半个世纪的研究热点,暗管排盐技术的发明有效地解决了部分地区的土壤盐碱化问题,成为盐碱地治理领域的重要手段。文章综述了暗管排盐技术的发展概况,对暗管排盐关键技术进行了剖析,从管材选择、排盐管的埋深、排盐管的埋设、暗管排盐工艺等方面,对暗管排盐关键技术进行了总结,分析了管排盐技术在不同地区的应用效果,提出了暗管排盐技术目前存在的问题及发展展望。

Saline-alkali land and regeneration Saline-alkali land were a worldwide problem. How to effectively controls Saline-alkali land was a hot research topic for nearly half a century. The invention of covered pipe salt draining effectively solved Saline-alkali land in party areas, and became the important means of controlling Saline-alkali land. Development situation of covered pipe salt draining technology was sumed up and covered pipe salt draining technology was analyzed from choosing of the pipe, the depth of the covered pipe, the method of laying covered pipe, the process of draining salt and so on. The key technology of covered pipe salt draining was sumed up and the technology of covered pipe salt draining in different areas was analyzed.It raised the problem of covered pipe salt draining technology at present, and developed prospect of covered pipe salt draining technology.
