摘要
盐碱地遍布于我国各省市,其作为一种不可替代的土壤后备资源,极具修复价值及高值利用潜力,改良盐碱地是缓解我国土地资源供需失衡的有效途径。本文从国家宏观发展战略及民生保障等方面论述了盐碱地改良的必要性,重点介绍了耐盐碱作物育种培育、物化改良、农业生物修复、工程水利灌溉等当下盐碱地改良的主流技术,同时根据盐碱地的差异性成因及因地制宜治理原则,提出了可持续改良盐碱地的未来发展建议。
Saline-alkali land is widely distributed across various provinces and cities in China.As an indispensable soil reserve resource,it has significant potential for restoration and high-value utilization.Improving saline-alkali land is an effective way to alleviate the imbalance between land resources supply and demand in China.This article discusses the necessity of saline-alkali land improvement in terms of national macro-strategic development and people's livelihood security,and focuses on introducing the current mainstream technologies for saline-alkali land improvement,such as breeding and cultivating salt-tolerant crops,physical and chemical improvement,agricultural biological remediation,and engineering and water conservancy irrigation.At the same time,based on the different causes of saline-alkali land and the principle of adapting measures to local conditions,suggestions for the future sustainable improvement of saline-alkali land are proposed.
