Effect of Treating Approaches on Microbial Community of Bio-organic Manure

The purpose of this study was to investigate the correlation between the treating approaches and microbial community of bio-organic Manure. The effects of different treatment methods on the microbial community dynamics of bio-organic manure added to microbial fermentation agents with production experiment method were studied. The treatment methods included C/N, ventilation system, and moisture content. The numbers of microbe were tested by conventional microorganism separation and purification method. The results showed that the best treatment methods were C:N 25:1, turning 3 times for compost and the initial moisture content of 65%, no longer increasing water. In these conditions, the numbers of fungi and bacteria of bio-organic manure were the best among all treatments, while the growth of mould was inhibited. The experiment would provide a theoretical reference for the establishment of standard system of biological organic manure fermentation.
