摘要: |
针对水资源短缺和盐碱地不断恶化等问题,理论上,微咸水灌溉农作物受到大量研究者关注;实践上,微咸水灌溉土壤收到良好效果,但鲜有微咸水投入改良盐碱地的理论实践,缺少一定的理论的指导。兹对目前国内外微咸水灌溉的开发和利用的研究进展进行综述,总结微咸水灌溉技术的实践情况,阐明了微咸水灌溉对作物、环境和土壤水盐运动的影响,详细论述了微咸水灌溉提升作物产量且改良盐碱地的成果,分析其灌溉改良盐碱地的可行性,从而提出之后微咸水灌溉改良盐碱地的研究方向和实践操作。 |

Abstract: |
In view of the shortage of water resources and the deterioration of saline alkali land, a large number of researchers pay attention to the crops irrigated by brackish water in theory; in practice, the soil irrigated by brackish water has received good results, but there is little theory practice of improving saline alkali land invested by brackish water, lacking certain theoretical guidance. This paper reviews the development and utilization of brackish water irrigation at home and abroad, summarizes the practice of brackish water irrigation technology, expounds the impact of brackish water irrigation on crop, environment and soil water and salt movement, discusses in detail the results of improving crop yield and saline alkali land by brackish water irrigation, analyzes the feasibility of improving saline alkali land by irrigation, and puts forward the following suggestions Research direction and practical operation of salt water irrigation to improve saline alkali land. |
