Compound microbial agent as well as preparation method and application thereof

The invention provides a compound microbial agent and application thereof, and belongs to the technical field of microorganisms. The compound microbial agent disclosed by the invention comprises aspergillus niger, ochrobactrum pseudo, bacillus xylanolyticus, bacillus subtilis and paenibacillus amyloliquefaciens, wherein the total viable bacterium concentration of the compound microbial agent is 2 * 10 < 8 >-2 * 10 < 10 > cfu/ml. The compound microbial agent provided by the invention has relatively strong degradation capability on lignocellulose, has no antagonism among strains, and can accelerate the composting process of agricultural organic wastes, promote compost maturity and improve the quality of compost products. 本发明提供了一种复合微生物菌剂及其应用，属于微生物技术领域。本发明的复合微生物菌剂包括黑曲霉菌、伪苍白杆菌、解木聚糖类芽孢杆菌、枯草芽孢杆菌、解淀粉类芽孢杆菌，所述复合微生物菌剂的总活菌浓度为2×108～2×1010cfu/ml。本发明提供的复合微生物菌剂对木质纤维素具有较强降解能力且菌株间不存在拮抗作用，能够加速农业有机废物堆肥进程，促进堆肥腐熟和提高堆肥产品质量。
