摘要:概述了国内外微咸水开发利用的研究现状、利用途径,并提出今后微咸水利用主要研究方向。首先要重视土壤盐分调控研究,防止土壤次生盐渍化,平衡土壤-水-作物系统;其次重视土壤水分和盐分运移特征以及平衡规律;然后是微咸水灌溉后,对土壤环境的影响,和盐分离子对作物生长发育的影响等,为今后微咸水开发利用理论的研究和发展奠定基础。

Abstract: This thesis has summarized the research status and utilization ways of brackish water development and utilization domestic and overseas, and has proposed the main direction of brackish water utilization in the future. Firstly, the regulating research of soil salinity should be attached importance to prevent soil from secondary salinization and to balance the system of soil, water and crops. Secondly, migration characteristic and balance rule of soil moisture and salinity shoul
