Abstract: The effects of four different organic fertilizer treatments, commercial organic fertilizer, vegetable waste compost, commercial organic fertilizer + microbial inoculum, vegetable waste compost + microbial inoculum on the physicochemical properties and catalase of vegetable greenhouse soil were studied. The results show that each treatment can significantly reduce soil pH, increase soil organic matter content and cation exchange capacity, reduce soil bulk density and increase soil porosity to a certain extent, and the effect of adding microbial inoculants is more obvious. The content of alkali-hydrolyzed nitrogen in each treatment increased significantly, and the content of available phosphorus and available potassium increased to varying degrees. The effect of compost treatment of vegetable waste was better. Each treatment can increase the content of catalase in the soil. The composting effect of vegetable waste is better than commercial organic fertilizer. The effect of composting vegetable waste compost with microbial inoculum is better. Each treatment can effectively improve the physical and chemical properties of the soil and increase the biological activity of the soil. The effect on the soil from strong to weak is vegetable waste compost + microbial inoculum, commercial organic fertilizer + microbial inoculum, vegetable waste compost, and commercial organic fertilizer.

Key words: vegetable waste, microbial inoculum, commercial organic fertilizer, soil fertility, enzyme activity
