Preparation method and applications of fungus chaff compost inoculum

The invention discloses a preparation method and applications of a fungus chaff compost inoculum. The compost inoculum provided by the invention contains the active ingredients including bacillus subtilis, brevibacillus thermoruber, brevibacillus reuszeri and brevibacillus laterosporus at the CFU ratio being (1-2) to (1-2) to (1-2). For the inoculum provided by the invention, the bacterial strains rapidly proliferate together under the micro-oxygen condition, so that lignocellulose is efficiently decomposed. For the inoculum, the preparation process is simple, the decomposition function is stable, and the expiration date is long. In the embodiment, for an inoculum group in which the inoculum is fed, compared with a control group in which the inoculum is not added, the composting time is shortened by 6 days, the degradation rates of cellulose, hemicellulose and lignin are improved by 5.69%, 6.70% and 4.57% respectively, the loss ratio of total nitrogen is reduced by 9.44%, the content of humus is improved by 1
