Study on Microflora and Enzyme Activity in Rhizospheric Soil of Paeoniasuffruticosa

To understand the effect of planting peony on soil micro-ecosystem,taking the soil cultivated Paeonia suffruticosafor several years as material,the study on rhizosphere microflora and soil enzyme activities of Paeonia suffruticosa was studied.The results showed that the total microflora quantity of rhizosphere was greater than that of the non-rhizosphere,and bacteria in two kinds of the soil were dominant,while the content of fungi in non-rhizosphere soil was higher than that in the rhizosphere.Compared with those in the non-rhizosphere,the activities of urease,alkaline phosphatase and neutral phosphatase were increased by 38.40%,81.76%and 129.42%.Polyphenol oxidase had little difference,but the activity of catalase in the non-rhizosphere increased by 5.31%than that in rhizosphere soil.
