摘要

A pot experiment was conducted by putting ameliorants,the products of plants fermented by lactobacillus,and sandy soil into alkaline-saline soil. After such blending,the soil physicochemical properties and the growth index of Alfalfa seedlings were measured in order to explore the influence of the blending on alkaline-saline soil and the growth of alfalfa seedlings. The results showed that soil p H decreased significantly after adding ameliorant; mixing ameliorant and sandy soil into alkaline-saline soil reduced soil evaporation and increased the germination rate of alfalfa seeds and their chlorophyll content as well as the seedling height,root length of alfalfa seedlings,but it had no significant effect on alfalfa seedlings’ biomass and leaf number; besides,excessive ameliorant would inhibit the growth of alfalfa seedlings.
