Successive cropping obstacle auto-toxic material degradation bacterium and compound microbial fertilizer prepared by same

The invention relates to a auto-toxic material degradation bacterium. The collection institution of the auto-toxic material degradation bacterium is China general microbiological culture collection center, the collection number is CGMCC No. 6896, the collection date is 30th, November, 2012. The compound microbial fertilizer consists of compound microbial agent and ammonia humic acid according to the weight ratio of (2-3):(7-8). By degrading the auto-toxic material in the soil, enhancing a soil granular structure and constructing effective microbial community strength, the formation of the soil granular structure is enhanced, a micro-eco-system of the soil is greatly improved, the permeability of soil is enhanced, and the moisture and fertility preserving capability of the soil are improved. By adoption of the auto-toxic material degradation bacterium and the compound microbial fertilizer, the soil has the development potential of sustainably increasing both production and income; and in addition, a base ferti
