Abstract:

In order to meet the daily demand of eggs,milk and meat,livestock and poultry breeding industry develops rapidly,and at the same time,a large number of livestock and poultry excrement is in urgent need of treatment. Composting,as an efficient,harmless and resource-based treatment method,has been widely used in the treatment of livestock and poultry manure. Livestock manure composting is a process in which unstable organic matter is decomposed and converted into stable humus through microbial activities. Understanding the succession of microbial community is an important basis for developing new methods and theories of composting. In this paper,the microbial community structure and functional succession in different stages of livestock manure composting are sorted. The characteristics of starting materials（water content,pH,C/N,etc.）and the effects of human activities（aeration and inoculant inoculation）on microbial community succession of compost are summarized. The current methods of studying compost microbial community are compared. Some scientific problems and research directions of livestock manure composting in the future are proposed,and provide support for guiding the future work.

Key words: livestock manure compost, composting microorganism, structure succession, function succession
