Livestock manure causes serious environmental pollution problems， and aerobic composting can realize the harmless treatment of livestock manure. However， traditional aerobic composting still has problems such as slow temperature rise， long cycle， serious nutrient loss and serious odor volatilization， and the efficiency and quality of composting need to be further improved. The addition of external microbial inoculants can improve the traditional natural composting process of livestock manure. The functional strains for composting fermentation were screened by analyzing the enzyme production and deodorization ability of the strains， and two kinds of compound microbial inoculants were obtained to develop the microbial inoculants with high efficiency of degradation， transformation， deodorization and nitrogen-fixation for aerobic composting of livestock and poultry manure， and to further improve the efficiency and quality of composting. The effects of adding compound microbial inoculants on the conventional physical and chemical indexes， the activity of cellulase and urease， the loss of nitrogen and the product quality of aerobic composting of chicken manure were studied. The results showed that the compound microbial inoculant significantly increased the cellulase activity of the composting due to its higher ability to degrade organic matter， and the activity of cellulase reached 4.937 U/g at the later stage compared with the control and the compound microbial inoculant Ⅲ. Adding compound microbial inoculant Ⅰ significantly increased the temperature of the composting， and the maximum temperature reached 65.8 ℃， which was 5.8 ℃ higher than that of the control. The compound microbial inoculant Ⅱ significantly reduced the activity of urease and the loss of nitrogen of the composting because it contained the bacteria with strong ability of deodorization， and the loss of nitrogen was lower than that of the control. The content of total nutrient and the quality of compost products were improved by adding compound microbial inoculant Ⅱ， and the total nutrient of compost products was 5.32%， which was higher than that of the control（4.52%）. The addition of compound microbial inoculant Ⅰ and Ⅱ both accelerated the maturity of compost. On the 7th day of composting， the GI of seed germination index of adding compound microbial inoculant Ⅰ and Ⅱ was 75.12% and 75.29%， while the GI of the control was only 47.89%. It is indicated that the compound microbial inoculants developed has a good effect in the application of aerobic composting of chicken manure， which can increase the temperature of composting and the activity of cellulase， reduce the activity of urease and the loss rate of total nutrient and nitrogen of compost products.
