摘　　要：为了解牡丹种植对土壤微生态系统的影响,以多年种植牡丹的土壤为研究对象,对其根际微生物区系及根际土壤酶活性进行研究。结果表明:牡丹根际土壤微生物总数量大于非根际土壤,两类土壤中细菌占主要优势,但非根际土壤中真菌的含量高于根际土壤。根际土壤脲酶、碱性磷酸酶和中性磷酸酶的活性分别比非根际土壤增加了38.40%、81.76%和129.42%,多酚氧化酶差异不大,而非根际土壤中的过氧化氢酶比根际土壤增加了5.31%。To understand the effect of planting peony on soil micro-ecosystem, taking the soil cultivated Paeonia suffruticosa for 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-rhizo- sphere,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.
