摘  要：
通过田间试验测定不同密度毛苕子(Viciavillosa)处理的可溶性盐分及盐分离子,研究了毛苕子对次生盐碱地的抑盐效应。结果表明:在0～100cm的土层中,高、中和低密度毛苕子地的平均可溶性盐分分别较对照降低78.5%,74.7%,71.1%;各处理间的平均可溶性盐分和对照比差异达极显著(SSR0.01);可溶性盐分降低最显著的是0～20cm土层;毛苕子对可溶性盐分和盐离子层次分布影响结果是形成表层高—中层低—下层高的态势;随总可溶性盐分量的减少,盐分离子组成也相应地发生变化,毛苕子能显著增大盐碱地的K+/Na+;不同密度毛苕子处理的K+、Na+、Ca2+、Mg2+、Cl-规律性较好而SO42-欠佳。毛苕子改良盐碱地可开发盐地草产业,生态、经济效益俱佳,在西部内陆区次生盐碱地开发中具有广泛的农学意义。

摘  要：
Soluble salt content and different salt ions content were measured in different density Vicia villosa fields for studying the effect of soil salt restraint on Vicia villosa. The results showed that in 0~100 cm soil layer, the average soluble salt content in high, middle and low density Vicia villosa fields was 78.5%?74.7% and 71.1% less than that in the control respectively, the average soluble salt content in different treatments and the control is very significant difference (SSR 0.01 ) on statistic analysis; in 0~20 cm soil layer, the average soluble salt content decreased most obviously; With deepening of soil layer, various of soluble salt content and the salt ions content was as following: high in surfacelow in middlehigh in bottom; With decrease of soluble salt content, the salt ions content changed accordingly, K+/Na+ ratio reduce in salinization soil after planting Vicia villosa; In different density Vicia villosa treatments, K+,Na+,Ca2+,Mg2+ and Cl- had obvious law ,but SO42 was not. It is considered that planting Vicia villosa in salty land will play very important role in both developing economy and improving ecology environment in west salinization land.
