近年来,在我省东部平原特别是淡水匮乏的黑龙港地区,为了缓解淡水资源紧缺,已开始利用当地较多的地下咸水进行农田灌溉。但由于种种原因,特别是对咸水利用的条件缺乏了解,往往达不到预期的效果。现结合国外咸水灌溉最新发表的研究成果,谈谈咸水灌溉应该了解的几个问题。实际上,咸水灌溉在国外已不是什么新课题,有些国家利用海水灌溉也已获得成功。在国外的成功经验中,一个非常重要的先决条件是;咸水灌溉只适 In recent years, in the eastern plains of our province, especially in the area lacking fresh water, in order to alleviate the shortage of freshwater resources, irrigation has been started using more local saline water. However, due to various reasons, especially the lack of understanding of the conditions of salt water utilization, they often fail to achieve the expected results. Now combined with the latest published research results of saltwater irrigation in foreign countries, to talk about several issues should be aware of salt water irrigation. In fact, salt water irrigation is not a new issue abroad, and some countries have also succeeded in using seawater for irrigation. Among the successful experiences abroad, one very important prerequisite is that salt water irrigation is only suitable
