摘要： Poultry waste can be produced into high-quality organic fertilizers by composting. In this project, a microbial agent was constructed. The objective of this study was to analyze the effectiveness of additives (microbial agent ( TB) and manure compost (TM)) on composting process of chicken litter with mushroom residue. Results indicated that TB exhibited the highest composting temperature (72.1 degrees C) and TM exhibited the longest high-temperature period (10 days). TB nutrients were better retained compared to the control and achieving a final total nitrogen (TN), total phosphorus (TP) and total potassium (TK) at 1.92%, 5.38% and 4.61%, respectively. After composting, the TP increased 1.22% in the treatments with manure compost inoculation compared with initial phase, while it increased 0.95% in CK2. At the end of composting, TM had lower E4/E6 values and organic matter (OM) content compared to CK2 illustrating that the addition of mature compost enhanced the humification of compost. Operational taxonomic units ( OTUs) analysis revealed that TM increased microbial community diversity, however, TB decreased microbial community diversity compared to the control. Compared with the direct addition of a few specific microorganisms as microbial agents, the addition of mature compost can obviously increase the microbial species in the composting process, extend high-temperature period and promote fermentation process. Obviously, the above research results provide theoretical lessons on how to rationally add exogenous microbes to promote the composting process scientifically.
