The relation between soil enzyme activities and soil fertility factors in the low hill lands along Yantze River

Abstract

Abstract: Study on 6 soil enzyme activities and 7 siol fertility factors of 12 different planting modes,analyse the dates with the correlation analysis and the canonical correalation analysis,In order to reveal the relations between the soil enzyme activities and soil fertilities in the low hill lands along Yantze River , The result of the correlation analysis showed that they had a great relation between the soil enzyme activities and siol fertility factors. the result of canonical correlation analysis showed that there existed a significant canonical correlation between “Integral soil enzyme activity factor” and “Integral soil fertility factor”，among the test enzymes, peroxidase,urease, polyphenol oxidase and amylase had great relations with the siol organic matter and total N. “Integral soil enzyme activity factor” can be used as an important index of soil fertilities.
