The relationships between soil enzyme activities and soil properties in acidified pear orchards were studied through field investigation and laboratory analysis.The correlation between enzyme activities and soil properties were evaluated by the methods of correlation and path analysis.The results showed that catalase,acid phosphatase and urease were significant differences with the increasement of soil depth in 4.0-4.5,4.5-5.0,5.0-5.5,5.5-6.0 ranges,in addition to invertase in 5.0-5.5 range.Meanwhile,water ...
