Abstract：Effect of fertilization on soil microflora mass and soil enzyme activity between rhizosphere and non-rhizosphere space in I-107 poplar forestland was studied, and the correlation between soil enzyme activity and soil microflora was analyzed.Results showed that,fertilization treatment increased both rhizosphere and non-rhizosphere total soil microflora amount significantly,compared with CK.Amount of soil microflora in organic fertilizer treatment was more than urea treatment and biological fungus fertilizer treatment.Activity of soil urease,alkaline phosphatase,catalase,peroxidase all increased significantly in every fertilization treatment,but activity of polyphenol oxidase in urea and biological fungus fertilizer treatment decreased.Soil enzyme and(microflora) rhizosphere effect of urea fertilizer treatment and biological fungus fertilizer treatment was less than(organic) fertilizer treatment.Soil pH value of urea fertilizer treatment was more than CK,and that of biological fungus and organic fertilizer treatment was less than CK.Rhizosphere effect value of soil pH in different treatment had no difference.Correlation between soil urease activity and cellulose decomposing bacterium,soil(alkaline) phosphatase activity and ammonificator,fungi,actinomyces,nitrosotying bacteria,soil catalase and cellulose decomposing bacterium,fungi,actinomyces was significant at 0.05 levels.
