摘　　要：简要介绍了耐盐牧草改良盐渍化土壤的机理。盐渍化土壤种植耐盐牧草后,土壤理化性质发生明显改变,土壤结构趋于好转,土壤表层盐分含量逐渐降低,养分含量逐渐增加。利用牧草改良盐碱地的"生物治碱"措施是行之有效,长期稳定的改良盐渍化土壤的方法。The mechanisms of saline-soil improvement using salt-tolerant forages are introduced in this article. After planting salt-tolerant forages, the physical and chemical properties of the soil changed markedly, the soil structure improved, the salt content of the soil surface layer gradually reduced, and the nutrient content gradually increased. It is an effective and long-term-stable way of improving saline-alkali soil.
