Effect of sulfur application to soil enzyme activity of Vaccinium vitis-idaea L. root zone.

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.
