摘要
采用田间试验测定不同比例硫磺粉对越橘Vaccinium vitis-idaea L.根域土壤酶活性的影响.结果表明:随着土壤施S量的增加,越橘根际和非根际土壤酶活性均表现先升高后降低的变化规律,加入1.5和2.0 kg/m3 S的处理,各种酶活性高.脲酶、磷酸酶、蛋白酶活性根际大于非根际,CAT活性非根际大于根际,高峰均出现在生长前期.
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.
