Efficient fermentation bed with microbial agents and preparation thereof

The invention discloses a microbial inoculum for a high-efficiency fermenting bed and a preparation method thereof. The microbial inoculum is prepared by thoroughly and evenly mixing 30-40% of Bacillus subtilis leavening powder, 30-40% of Bacillus licheniformis leavening powder and 20-30% of Candida utilis leavening powder. The microbial inoculum can effectively promote in-situ degradation of livestock and poultry excrement, obviously reduce the generation of ammonia and other putrilages in the livestock and poultry excrement, and enhance the quality of pork.
