Abstract：We investigated the effects of fermented corn straw on fertility of saline-alkali Soil based on pot experi-ments by taking unfermented corn straw as the control.In the experiment,we analyzed the changes in soil fertili-ty after applying a mixture of straw and slugged fermented corn straw at ratios of 1:1,2:1,3:1,and 6:1,at appli-cation rates of 1.25 g/kg, 2.50 g/kg, 3.75 g/kg and 5.00 g/kg respectively to a saline-alkali soil. The results showed that applying fermented corn straw significantly improved soil organic matter and bioavailable potassi-um,but decreased the bioavailable nitrogen and phosphorus.When the ratio of straw to fermented corn straw was 2:1 and the application rate was 2.50 g/kg,the microbial biomass-C and N were enhanced and they were 0.90 times and 1.07 times higher than those in the original soil;the soil enzymatic activity also increased significantly. In particular, the alkaline phosphatase, urease, cellulase and catalase increased by 54.47%, 37.00%, 33.82%, 59.77% compared to those in the original soil.
