The results showed that Bacillus subtilis of different ratios was added, Trichoderma koningii and Thermo actinomycetaceac could promote the decomposition of aging dunnage, especially composite microbial agents （Kc：Kn：Gf = 1：1：1 ） had the best effect of decomposition, the high tem- perature was kept for 13 days. In the end of composting, degradation rate of cellulose, degradation rate of lignin, GI, and C/N were 47.6%, 30. 2%, 98.5%, and 18.5%. Bacillus coli was not detected.展开更多
