Pratacultural College, Gansu Agricultural University, Lanzhou 730070, China) Abstract Soil acidification or alkalization has been a serious global environmental problem. It has not only caused huge losses of agricultural production, but also has been a seriously threat to ecological environment. Therefore, a simple and effective soil improvement method was critical for environmental protection and agricultural production. A group of lignocellulose microbial community was selected from soil samples of cattle and chicken feces compost. The selection was based on restrictive training in an effort to get
