Differentiation of Soil Enzyme Activities in Different Soil-Heavenly Bamboo Systems
不同土壤-南天竹系统的土壤酶活性分异

The restoration of limestone-degraded ecosystem may improve soil substrate.Heavenly bamboo was planted to pots in three different soil types(black limestone soil,yellow soil,purple soil) in order to do research on the soil enzyme activities.The results show the activities of amylase,alkaline phosphatase,and asparaginases in black limestone soil are higher than the other two soil types.But the activities of urease,peroxidase and polyphenol oxidase in purple soil are higher than that in the other two soil types.All the differences among them are significant(p<0.05).The correlation among soil enzyme(acti-)(vities),soil phosphorus and pH are not significant,while the correlation among some soil enzyme(acti-)(vities),soil nitrogen and moisture content in different soil types are significant(p<0.05).Different soil types show different correlation.Different soil enzymes show different correlation,too.The results can give some advices on the restoration of limestone-degraded ecosystem.
