咸水灌溉实施及管理的研究进展(英文)

General Advancement of Research on Saline Irrigation Practices and Management

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。

In this paper, different ideas and essential fundamentals proposed for efficient and better saline practic and management are reviewed and discussed. Fkst of all,the potential of using saline water in irrigation is anylized. And then the management practices under saline water irrigation is discussed mainly from several aspects ,i. e. irrigation scheduling, interval and method. At last,the leaching technique is detailed as an effective method to control soil salinity under Saline Water Irrigation.The author proposes several points; (1) Plant growth is a function of the salinity and matric potential of the soil water; (2) Leaching scheduling is important to the efficient control of salinity; and (3) Different irrigation methods have different soil responses to Saline Water Irrigation.
