Enzyme activities in Phytolacca acinosa Roxb. rhizosphere and non-rhizosphere soil polluted by manganese scoria
锰矿尾渣污染土壤商陆根际和非根际土壤酶活性

The study on the soil enzyme activities in Phytolacca acinosa Roxb.rhizosphere and non-rhizosphere soil of Xiangtan manganese mine showed that all tested enzyme activities were higher in rhizosphere than in non-rhizosphere soil.The effects of rhizosphere environment on the soil enzyme activities were in the sequence of invertase > urease >dehydrogenase> acid phosphatase >catalase,and the R/S value was 1.622,1.598,1.586,1.485,1.328,respectively.The tested enzyme activities were negatively correlated with soi...
