德州市土壤盐渍化概况及改良利用的研究

Soil Salinization Status and Its Improvement and Utilization in Dezhou City

本文主要论述了德州市土壤盐渍化分布概况及主要改良利用技术,对轻度盐渍土实行土壤隔层、抑制地表返盐碱,引黄灌溉、大水压碱,扩大肥源、林农配置等;对重度盐渍土采取生物治理与设施隔盐技术;对盐碱涝洼地采取了台基鱼塘和发展种植养殖业,为改良利用盐渍化土壤提供了有效途径。

The distribution of soil salinization and the techniques for its improvement and utilization were discussed in this paper. For slight saline - alkali soil, the soil segregating layer and Yellow River irrigation, increasing fertilizer source, shifting cultivation of forestry and crops and so on could be adopted, while the biological measures and the method using facilities to segregate salt could be applied to severe saline - alkali soil. In the saline - alkali lowland, developing planting and feeding industry was the effective method for improving and utilizing saline alkali soil.
