Study on Application Effects of Different Straw Decomposing Inoculants in Maize Straw Crushing and Returning to Field

In order to study the application effects of different straw inoculants,4 kinds of straw inoculants were chosen for tests of maize straw decomposing degree,physicochemical properties change of soil and effect of wheat growth and yield.The results showed that application of straw decomposing inoculants could reduce the bulk density and pH value of soil,increase the content of soil nutrient,and increase the yield of wheat significantly by 4.85% to 7.69%.
