YUE Zhong-hui, ZHANG Xing-yi, SUI Yue-yu, et al. Distribution Characteristics of Soil Enzymatic Activities in Black Profiles and Their Evaluation to Soil Nutrients[J]. 2011, 25(4).DOI:
invertase and nitrate reductase activities in nine soil profiles at black belt in Heilongjiang province were studied.The results showed that five enzymatic activities reduced in turn from 0 cm to 40 cm layer but catalase
invertase
nitrate reductase activities got to stabilization or increased a little
while phosphatase
urease activities reduced sharply even to zero below 40 cm layer.Correlation analysis showed that there were notably correlation be...
