摘要
微咸水开发利用不仅有利于缓解水资源短缺问题,而且有利于地下水资源更新、淡水存储和环境生态建设与保护.微咸水灌溉带入农田大量盐分,改变土壤物理和化学特征,影响作物对水分和养分的吸收及作物生长过程,这些是合理科学而安全利用微咸水进行农田灌溉所关注的核心问题.因此微咸水灌溉条件下的土壤水盐分布特征及水盐调控方法研究,对于微咸水灌溉条件下维持土地可持续利用具有重要的科学意义和实际应用价值.分析当前研究现状并提出今后有待于进一步研究的问题,为微咸水安全利用提供参考.
The utilization of saline water is beneficial not only alleviate the water shortage, but also conducive to update the groundwater resources, fresh water storage and ecological construction and protection of the environment. Saline water carrying a lot of salt into farmland and change the soil physical and chemical characteristics, the impact of crops on water and nutrient absorption and plant growth process, it is the core issue of reasonable and safe use of saline water for irrigation. Therefore, the research on irrigation technique of saline water and regulation and control method of soil water and salt is an important scientific significance and practical application value for sustainable use of farmland. This paper analyzes the current research status and the issue to be further studied for the safe use of saline water to provide reference.
