Taking Changbai 9 as experiment material, effect of different concentrations of saline-alkali stresson growth and yield of rice was studied in the paper. The results showed that a decrease tendency with different de-gree in dynamics of rice tillering, leaf area, dry matter accumulation and yield of rice in different concentrations ofsaline-alkali stress. Compared with CK, there were no significant differences on tillering, leaf area, dry matter accu-mulation and yield when soil salt content was 2.20‰, but there were significant differences when soil salt contentwas more than 2.20‰. So that it can be used as an important reference index for rice planting of saline-alkali soil,soil improvement and comprehensive utilization when soil salt content was 2.20‰, pH was 7.92 and electrical con-ductivity was 200.13 us/cm.
