Abstract
The effects of bio-compound fertilizer on soil microorganism were assessed using plate count method,CHCl_3 fumigation-extraction method and Biolog micro-plate technique on potted corn plants in greenhouses.Results showed that bio-compound fertilizer treatment increased the number of bacteria,fungi and actinomycetes in soil.The fertilizer treat- ment also increased the amount of C and N in soil microbial biomass,and the capacity to utilize single carbon substrate, it also increased biediversity and evenness of soil microbial community.Therefore,the bio-compound fertilizer treatment was beneficial to the diversity and function of soil microbial community.It also promoted the stability of soil ecological system and improved ecological functions of soil microbial community.
