In order to provide bio-organic fertilizer references in the process of blueberry growth, blueberry was selected as test material, the effect of bio-organic fertilizer on soil microbial properties and nutrients in blueberry root zone was examined. The results are as follows. (1) The bio-organic fertilizer (BOF) had significantly increased the soil moisture (p < 0.01), and significantly decreased the soil pH, bulk density and total porosity in blueberry root zone (p < 0.01). (2) BOF had significantly increased the soil nutrients, the contents of soil organic carbon, total nitrogen, total potassium, effective phosphorus and effective potassium in blueberry root zone were significantly higher than those of CK (p < 0.01), the soil available nutrients rapidly increased, while BOF had no significantly effect on soil total phosphorus (p > 0.05). (3) BOF had significantly increased the soil acid phosphatase activity and soil urease activity and sucrase activity and catalase activity in blueberry root zone, which were significantly higher than those of CK (p < 0.01). (4) BOF had significantly increased the soil microbial biomass in blueberry root zone, which was significantly higher than that of CK (p < 0.01), and was more sensitive to soil nutrients and could effective evaluate the effects of bio-organic fertilizer. (5) BOF also significantly raised the contents of microbial biomass carbon and microbial biomass nitrogen, accelerated microbial turnover rate, shortened microbial turnover time, increased microbial transfer capacity and activate soil microbial activity, which was beneficial to recycling and maintaining soil fertility. In total, BOF could effectively promote the soil nutrition absorption and metabolic coordination equilibrium, and ensure the higher yield and quality of blueberry.
