作者综述讨论了有关利用咸水灌溉及其管理的各种观点和基本建议。首先分析了利用咸水灌溉的潜力,从灌溉制度、周期及灌水方法几个方面详细讨论了咸水灌溉的实施及管理,最后研究控制土壤盐分的淋洗的技术问题,包括如何选择淋洗时间的技术问题。作者提出自己的几个观点。①作物生长是土壤盐分及质势的函数;②淋洗盐的适宜技术对有效控制土壤盐分很重要。③为有效合理安全使用咸水灌溉需特别考虑采用的灌溉方法,它们引起的盐分分布各有特点,应采用有效的控盐措施与之相适应。
The authors reviewed various points of view and basic advice on the use of brackish water for irrigation and its management. First, the potential of using saltwater irrigation is analyzed. The implementation and management of saltwater irrigation are discussed in detail from the aspects of irrigation system, period and irrigation methods. Finally, the technical problems of leaching salinity control are studied, including how to choose the leaching time Technical problems. The author put forward some of his own views. ① crop growth is a function of soil salinity and mass potential; ② appropriate technology for leaching salt is very important for controlling soil salinity effectively. ③ In order to effectively, reasonably and safely use salt water irrigation, the irrigation methods adopted should be specially considered. The salt distribution caused by them all have their own characteristics. Effective salt control measures should be adopted to adapt them.
