Abstract: Providing the most suitable fertilization treatment for crop cultivation in saline alkali soil often involves application of biological fertilizer. Using Baiyan 2 as the material, a greenhouse experiment was conducted to study the effects of mixed application of bacterial manure with nitrogen and phosphorus fertilizers on salt alkali resistance. The results showed that the content of alkali hydrolysable nitrogen, available phosphorus and available potassium could be increased in the saline alkali soil. In addition, the soluble protein increased, the content of proline decreased,and the effects of the treatment of mixed fertilizers was the most significant in the procreation period. Use of biological fertilizer and mixed biological/mineral fertilizer could improve salt tolerance of crop and soil nutrients could be increased.

Key words: Saline alkali soil;Biological bacterial fertilizer;Physiological indexes;Soil fertility
