不同秸秆腐熟剂在玉米秸秆粉碎还田中的应用效果研究

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

为验证大田条件下不同秸秆腐熟剂的应用效果,选择了4种秸秆腐熟剂,研究其对玉米秸秆粉碎还田腐熟程度、土壤理化性质、小麦生长发育及产量的影响。结果表明：施用秸秆腐熟剂能够降低土壤容重和pH值,增加土壤养分含量,显著提高小麦产量,增产幅度为4.85%～7.69%。

In order to study the application effects of different straw inoeulants,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 inoeulants 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%.
