The study of dynamic change of enzymatic activities in Chrysanthemum field with different coating material

the effect of dynamic change activities of enzymatic in Chrysanthemum 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 Chrysanthemum 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 0.26mol/L. that of soil sucrase increased 1.72 mg/g. that of soil urease increased0.08 mg/g and that of the Stalk weight increased 2.0 g/strip. That was beneficial to the improvement of soil enzyme activity of coated compound fertilizer as raw materials oil of Idesia polycarpa var. vestita.
