对八种非秋眠苜蓿在土壤含盐量０．２％～０．８％范围内的出苗率与成活率、相对株高、相对鲜重进行研究的结果表明，在土壤盐含量为０．２％～０．５％时可基本保证苜蓿的正常出苗与生长，部分品种对０．６％的盐浓度有忍耐性。
The results of germination rate, survival rate, relative plant height and relative fresh weight of eight non-fall dormant alfalfa cultivars in the range of 0.2% ~ 0.8% of soil salinity show that the soil salt content is zero. 2% ~ 0.5% can basically ensure the normal emergence and growth of alfalfa, some varieties have tolerance to salt concentration of 0.6%.
