After fertilization of different sulfur powder in field experiments, the soil enzyme activities and soil pH values of Vaccinium titis-idaea L.,blueberry, root zone were determined. The soil enzyme activity of blueberry rhizosphere and non-rhizosphere both showed increase first and then decline. After adding 1.5 and 2.0 kg/m³ sulfur, the activity of soil urease, phosphatase, protease in rhizosphere was higer than non-rhizosphere, CAT activity of non-rhizosphere was higer than that of rhizospere. The high activity of the tested enzymes appeared in the early growth.
