Microbes play a crucial role in composting, and antagonistic bacteria, as a biological control agent, can compete with pathogens and harmful microorganisms to maintain the stability and quality of composting. This paper compared the effects of different inoculation methods on antagonistic bacteria and nutrients in composting, and found that inoculation quantities between 10^6-10^7 cfu/g could improve the antagonistic effect and nutrient content of composting, regardless of direct inoculation or pre-treatment inoculation, and pre-treatment inoculation could better promote the growth and reproduction of antagonistic bacteria. These results will provide reference for improving the quality of composting and reducing environmental pollution.Keywords: Composting; Microbe; Antagonistic bacteria; Inoculation method; Nutrient
