摘要
对目前国内外咸水灌溉的研究与利用状况进行了概述,阐明了利用咸水灌溉的重要意义,以土壤和作物为研究对象,详细论述了目前咸水灌溉研究的成果,咸水灌溉中小定额,小流量易于积盐;大定额,高频率灌水易于洗盐;各种植物及植物的各组织对于盐分的适应能力不同,咸水灌溉要综合考虑。许多咸水灌溉研究成果对于实际的生产有很重要的指导意义,但是目前的研究还有很多需要完善的地方。
The paper summarized the research and utilization stituation of salt water irrigation at home and abroad,explains the important meaning of using salt water for irrigation,taking soil and crops as research objects,narrates present research results in this aspect in detail.In salt water irrigation,small irrigation guota and small discharge may lead to accumulate salt in soil,large irrigation guota and high freguency irrigation can leach salt content in soil,different kinds of plants and plant's organs have different capacity to adapt soil salt content.Salt water irrigation must consider these factors comprehensively.Many research results of salt water irrigation have imporatant direction sense for actual agriculture production,but many issues in salt water irrigation still remain to be solved and prefected.
