Effect of dynamic change of activities of enzymatic in Sugarcane field with different coating material

摘要

the effect of dynamic change activities of enzymatic in Sugarcane field with different coating material was studied With three kinds of coated compound fertilizer as raw materials. Results show that the soil enzymatic activities of catalase, sucrase and urease increased first and then decreased at different sugarcane growth stage;;By comparing the Coated compound fertilizer of coated materials of Idesia polycarpavar.vestita with CK, we realized the quantity of soil catalase increased 0.03mol/L, that of soil sucrase increased 0.91 mg/g, that of soil urease increased 0.05 mg/g and that of the production increased 23.7%. That was beneficial to the improvement of soil enzyme activity of coated compound fertilizer as raw materials oil of Idesia polycarpa var.vestita.
