摘要： An experiment was conducted in a paddy soil to investigate the responses of soil microbial community to a Chinese local phosphate rock sampled from Kunyang, Yunnan Province ( KPR) application and annual ryegrass by using phospholipid fatty acid (PLFA) analysis. Results showed that ryegrass planting induced the symbiosis of vesicular-arbuscular mycorrhizae indicated by PLFA 20:4. KPR application produced significant (p<0.05) decline of bacterial and actinomycetic biomass indicated by PLFAs concentration compared with no P application in the absence of plants. Fungi biomass was significantly increased after KPR application in the presence of plants. Changes of soil microbial community structure after high rate of KPR application in the presence of plants may be caused by the interactions between phosphate rock application and ryegrass.
