Abstract: To clarify the influence of microbial inoculum on composting process and product quality of chicken manure industrial composting, and control the process of commercial organic fertilizer production, an experiment was conducted. We selected chicken manure and rice husk as the raw material, set treatments with adding microbial inoculum or not, conducted the 40-day windrow composting, and analyzed the related indexes of composting process and quality. The results showed that the temperature of CK and MI remained above 50℃ for 21 days and 22 days, respectively, which reached the high temperature compost hygiene standards. Compost product of CK and MI had no significant difference on a series of process and maturity parameters, such as pH value, EC and moisture content. Therefore, the blank contrast test of microbial inoculum should be carried out in production, so as to avoid unnecessary cost. In addition, the solid phase carbon and nitrogen ratio of the compost material is relatively high, which seriously slow down the composting process. To increase the benefits of enterprises, it is necessary to optimize and adjust the compost process parameters.
