Abstract: This work aims to study on the effect of Morchella mycelium on soil enzymatic activity. The sucrase and amylase activities of soil samples were determined by 3,5-dinitrosalicylic acid colorimetric method with single factor and orthogonal experimental design. The optimal condition of the soil sucrase activity was that the temperature was 28℃,the time was 3 d,the amount of added mycelium was 1∶5,and the soil sucrase activity increased 12 times compared with the control group. The optimal condition of soil amylase activity was as such:the amount of added mycelium was 1∶5,the temperature was 28℃,the time was 7 d,and the soil amylase activity increased 18 times compared with the control group. Morchella mycelium can improve the sucrase and amylase activities in the soil in a short period of time,which is of significance for improving soil.

Key words: Morchella mycelium, sucrase, amylase
