Abstract: In order to investigate the effects of exogenous organic materials on Chinese herbal residues composting,taking the traditional Chinese medicine residue compost (CK,100% Chinese medicine residue)as control,the effects of adding chicken manure (T1,70% Chinese medicine residue+30% chicken manure),pig manure (T2,70% Chinese medicine residue+30% cow manure),cow manure (T3,70% Chinese medicine residue+30% cow manure) on the temperature,pH value,degradation of cellulose and lignin,changes of nutrients before and after composting and the number of viable bacteria after composting were studied.The results showed that the temperature of compost was increased,and pH value of compost was reduced after adding livestock manure, which was beneficial to the growth and reproduction of micro organisms,and promoted the degradation of cellulose and lignin in traditional Chinese medicine residue and the decomposition and mineralization of organic matter,thus speeding up the composting process.After composting,T1 treatment had the largest number of viable bacteria,reaching 0.72×109 cfu/g,which was 89.47%,33.33% and 125.00% higher than that of T2,T3 treatments and CK,respectively;C/N of T1 treatment was significantly decreased compared with the other three treatments, and T1 treatment had the highest degree of decay;while T1 treatment had the highest degradation rates of cellulose and lignin,which were 4.50%—15.42% and 6.14%—20.02% higher than that of the other treatments,respectively.It can be seen that adding chicken manure is more conducive to improve the process and humification of aerobic composting of traditional Chinese medicine residue.
