摘 要 ：通过室内外各项试验测定了碱地肤的耐盐性。结果表明：种子正常萌发的盐溶液浓度为8.1个大气压以下；在滨海盐化潮土上正常出苗的土壤盐渍度为0.55%以下，苗期以后能够正常生长发育的盐渍度为0.8%以下。碱地肤耐盐性较好的原因在于它能够吸收土壤中大量的无机盐进行渗透调节，降低水势、避免脱水；另外，它还具有一般稀盐植物的稀盐特征。

Abstract:In this paper, the salt toterance of Kochia scoparia var. sieversiana is studied with field survey and laboratory tests. The results show: The salt solution concentration for the normal seed germination is below 8.1 atmosphere pressure ,Salinity for the normal emergence of seedlings is below 0.55% and for the normal growth and development is below 0.8% when the plant is cultivated in coastal salinized soil.The reason why this plant has stronger salt tolerance may be that it is able to absorb and accumulate a lot of mineral salts to regulate the cell osmotic potential, lowering water-potential of cells and avoiding dehydration them. Besides, this plant also has the characteristic of salt-dilution.
