This study compared the decomposition effects of different microbial agents added to rice straw to screen for efficient and stable microbial agents and achieve effective utilization of rice straw resources. Different microbial agents can accelerate the decomposition of rice straw. The E4/E6 value of rice straw added with the Bacillus subtilis agent was significantly lower than that of rice straw added with other microbial agents on the 30th day. The lignin degradation rates for the Bacillus subtilis agent and Trichoderma viride agent treatments were higher than those of the other treatments fr...
