盐荒地改良,可以有各种方式,施肥是其中比较重要的一种。山东省陵县有盐荒地30多万亩,约占全县土地总面积的30%,如何使这些土地迅速地得到改良利用,已成为科研工作中的一个重要课题。为此,我们选择了一块水利工程基本配套的盐荒地,连续几年进行农业种植利用结合施肥,以观察其改良利用效果。 Salt wasteland improvement, there are a variety of ways, fertilization is one of the more important one. There are more than 300,000 mu of salt wasteland in Lingxian County, Shandong Province, accounting for about 30% of the total land area of ​​the whole county. How to make these land rapidly improved and utilized has become an important issue in scientific research. To this end, we have chosen a basic piece of salt water wasteland, for several years of continuous use of agricultural planting and fertilizing to observe the effect of improved utilization.
