在水利条件较好的地区,用水冲洗办法来开垦利用盐渍土,是一项快而简便的办法。 通过冲洗可以使盐分很重的土地,能够迅速地得到改良,及时地投入生产,因此很受人们重视。但是自然的和人为的因素,使水分在土壤中对盐分的溶解程度及其运动状况有所变化,因而也就影响到土壤冲洗脱盐的效果。 去年早春,我们与苏北盐城专区土壤研究所,曾就盐渍土的冲洗改良工作进行了初步的研究。现将试验所得研究资料,作一初步的总结,以供有关方面的参考。
In areas with better water conservancy conditions, it is a quick and easy way to reclaim and utilize saline soil by means of water flushing. By washing can make salt heavy land, can be quickly improved, put into production in a timely manner, so very much attention. However, natural and man-made factors, the water in the soil to dissolve the salt levels and their movement changes, which will affect the soil washing desalination effect. Last spring last year, we worked with the Institute of Soil Science, Yancheng Prefecture, Northern Jiangsu Province to conduct a preliminary study on the improvement of saline soil irrigation. Now the experimental research data obtained for a preliminary summary for reference by the parties concerned.
