摘　　要：【目的】引种内蒙古野生欧李到新疆昌吉,经过2年驯化后,研究欧李对新的环境下的土壤盐渍化的适应性,为欧李在新疆推广种植和综合开发利用提供基础理论依据。【方法】在盆栽条件下,不同浓度的NaCl溶液浇灌后,观察苗木的生长情况,测定苗木叶片的生理生化指标。【结果】用0.8%～1.6%盐液浇灌,对叶片的叶绿素含量、相对电导率、可溶性糖含量、保护酶活性等均增加,植株生长正常,具有一定耐盐能力;用2.0%～2.4%盐液浇灌,植株不能正常生长,甚至死亡。【结论】土壤盐分低于1.6%,引种的欧李能正常生长。[ Objective ] The purpose of this project is to study the salt soil adaptability of Cerasus humilis two years after it was domesticated from Inner Mongolia to Changji, Xinjiang . [ Method ] Under pot experiment conditions, the seedling growth was observed and physiological and biochemical indexes of seedling leaves with different concentrations of NaC1 solution were tested. [ Result ] The findings showed that： chlorophyll content, relative electrical conductivity, soluble sugar content and soluble protein content indexes changed in leaves with salt solution irrigation, but the seedling growth stopped with 2% - 2.4% salt solution irrigation until the seedlings withered or died. [ Conclusion] Prunus humilis can usually grow normally when the soil salinity was below 1.6%.
