Abstract：In order to explore the effects of different decomposition agents on the fermentation and decomposition charac-teristics of garden waste composting and on cabbage growth,11 kinds of fungal agents were used in the composting of garden waste.The changes of pH,EC value,organic matter content,C/N ratio,fulvic acid and humic acid content during the composting process,as well as the germination index of cabbage seeds composted with different fungal agents were analyzed.The compost with a germination index greater than 80％was selected for pot cultivation of cabbage,in combina-tion with chemical fertilizer.The leaf area,biomass and rhizosphere microbial number of the cabbags were measured for different combinations.The results showed that,except for CK-SY and M1-3 treatments,the pH of other garden waste composting with different fungal agents generally increased first and then decreased,while the EC value of most treat-ments decreased initially and then increased during the composting process.Among them,the EC value of BF32-93+T2-55 was always maintained at a low level(2389-2767 μS·cm-1),and exibited the fastest and most thorough rotting.The composting of garden waste with BF32-93+T2-55 microbial agent and chemical fertilizer treatment could significantly increase the leaf area,dry mass,and fresh mass of potted cabbage by 233.33％,276.47％and 192.86％,respectively,compared to CK.At the same time,the single application of BF32-93+T2-55 microbial agent was beneficial in increasing the proportion of disease-resistant microorganisms in the rhizosphere soil.
