Bioorganic fertilizer is vital for development of green organic agriculture, and there are a great variety of bio-organic fertilizers at home and abroad. It is of significance of screening appropriate local bioorganic fertilizers. In this paper, pakchoi was cultivated with four bioorganic fertilizers, dynamic changes of soil enzyme activities and amount of microorganism in the treatment with bio-organic fertilizer (2 g/kg) were detected by regular sampling in pot experiment. The results showed that bioorganic fertilizers could promote the activities of catalase and urease and reduce the amount of soil bacteria at the first week after fertilization. Bioorganic fertilizers significantly stimulated the bacteria proliferation, improved the activities of soil protease, sucrose and phosphatase in 2 weeks after fertilization. In 3 weeks after fertilization bioorganic fertilizers still promoted the activity of soil phosphatase, howerer, the other enzyme activity returned to control level. In 4 weeks after fertilization the activities of catalase, urease, protease and phosphatase and the amount of fungi in treatment with bioorganic fertilizer returned to control level. In the middle of detection, the abroad bioorganic fertilizer(BF1) could improve soil microbial properties when no chemical fertilizer was not applied, which needs to further study. The above results can provide the theoretical basis for selecting excellent bioorganic fertilizer.
