微咸水灌溉改良盐碱地的可行性研究

Feasibility Study of Improving Saline Alkali Land by Irrigation with Brackish Water

针对水资源短缺和盐碱地不断恶化等问题,微咸水灌溉农作物在理论上受到大量关注,在实践上也有良好效果,但鲜有微咸水投入改良盐碱地的理论实践,缺少一定的理论指导。对目前国内外微咸水灌溉开发和利用研究进展进行综述,总结微咸水灌溉技术的实践情况,阐明微咸水灌溉对作物、环境和土壤水盐运动的影响,详细论述微咸水灌溉提升作物产量和改良盐碱地的成果,分析其灌溉改良盐碱地的可行性,并提出微咸水灌溉改良盐碱地的研究方向和实践操作。

In view of shortage of water resources and deterioration of saline alkali land,irrigation with brackish water has received a lot of attention in theory and has good results in practice,but there are few theoretical practices to improve saline-alkali land with brackish water,which lacks certain theoretical guidance. Development and utilization of brackish water irrigation at home and abroad were reviewed,practice of brackish water irrigation technology was summarized,impact of brackish water irrigation on crop,environment and soil water and salt movement were expounded,results of improving crop yield and saline alkali land by brackish water irrigation were discussed in detail,feasibility of improving saline alkali land by irrigation was analyzed,and following suggestions for research direction and practical operation of salt water irrigation to improve saline alkali land were put forward.
