Abstract: In order to explore the influence of added exogenous microbes on compost starting process parameters, and study the change of compost starting process parameters with microbial and put forward the significance of the secondary regulation technology parameters. The effect of microbe on water content, pH, EC, total carbon, total nitrogen and carbon nitrogen ratio was studied by adding five different concentrations (0%, 0.25%, 0.5%, 0.75% and 1%) of thermophiles respectively. The results showed that the water content of 1% microbe treatment was 5.82% higher than that of control; PH and EC changed in different degrees; the carbon content of 0.25% microbe treatment was 9.20% lower than that of control; the total nitrogen content of 0.75% microbe treatment was 35.33% lower than that of control; the carbon nitrogen ratio of 0.75% microbe treatment was 4.34% higher than that of control. The results suggested that bacteria suspension could lead to different compost starting process parameters by adding different concentrations of exogenous microbe.
