摘　　要：灌溉水源短缺是我国农业持续发展面临的重大危机与挑战,如何解决这一问题有着重大的实际意义。微咸水灌溉是一种可行的开源途径,在我国不同地区针对不同农作物已经开展了深入的研究,需要及时而完整地总结相关的经验,以更好地指导未来微咸水利用的实践。以华北平原大田灌溉为基本农业类型,总结了微咸水灌溉成功施行的相关措施,包括可用水源的矿化度阈值、降雨淋溶以及相关农田管理措施对土壤盐分累积状况的影响和改善等,并针对微咸水灌溉实施条件下作物产量和品质方面可能出现的影响进行了总结。有助于人们多角度、从不同方面认识微咸水灌溉问题,为未来微咸水灌溉的实施提供了一些准则。The shortage of irrigation water is one of most severe challenge for sustainable agriculture.How to deal with this issue is of important practical significance.Using brackish water to irrigation is one possible new water source and a number of studies have been practiced in many places based on different crop.The related experiences need to be summed up in time to guide the correct practice of brackish water irrigation in the future.Take the field irrigation in North China Plain as an example,the salinity of brack-ish water used for irrigation,the role of rainfall leaching and related field management measures in maintaining brackish water irriga-tion agriculture,and the effects of brackish water irrigation in terms of crop yields and quality have been summed up.This summary will help to understand the brackish water irrigation issue at different angles,and provide some practice criterions of it in the future.
