Abstract

The effects of the controlled release bulk blending fertilizer(CRF) on the garlic rhizosphere soil enzyme activity were investigated by the field trial.The results showed that the activities of urease,phosphatase,sucrase and catalase increased significantly with the increasing application amount of CRF,and the activities of urease,phosphatase and sucrase of 100% and 80% CRF treatments were significantly higher than those of CCF treatment,which indicated that CRF could increase the soil soluble nutrient contents by enhancing the soil enzyme activity so as to increase the garlic yield.
