Effects of Microbial Inoculant on Process and Quality of Wheat Straw and Chicken Manure During Hot Composting

This paper introduced the effects of microbial inoculant CM and JM on the process and quality of hot composting with wheat straw and chicken manure in a static state,such as temperature,carbon nitrogen ratio(C/N),ammonium nitrogen(NH+4-N),and germinating index(GI) were determined.The results showed that,compare with no inoculant(CK),composting inoculated with CM and JM reach the highest temperature ahead of 3 days;the C/N of composting inoculated with CM and JM drop from 30 to 15,ahead of 10 days compared with CK;by composting of 20 days,the NH+4-N content of composting inoculated with CM and JM reach 1.42,1.54 g/kg respectively,less than 2.01 g/kg of CK obviously;by composting of 14 days,the GI of composting inoculated CM,JM and no inoculant is 57,48,32,respectively.The results indicate that CM and JM can improve the composting of wheat straw and chicken manure decompose rapidly,CM can increase the value of GI of compost compared with JM.
