摘　　要：采集自然状态下生长的黄连(Coptis chinensis Franch)根周围的3个土壤样本,以其附近空白区域土壤作为对照,对土壤样本理化性质、可培养微生物数量、微生物类群与群落结构进行分析。结果表明,与对照土壤相比,黄连根周围土壤pH、有机质含量、有效磷含量、有效钾含量、可培养真菌数量极显著提高;土壤全氮含量、可培养细菌总量整体上显著提高;硝态氮水平极显著降低;可培养放线菌数量整体上变化不显著;土壤原核微生物数量下降,病原真菌数量增加。Three soil samples around the roots of Coptis chinensis in the natural state were collected,and the surrounding blank areas were also collected as the control.The physical and chemical properties,cultivable microbial quantity,microbial groups,and commu⁃nity structure of these soil samples were analyzed.The results showed that,compared to the control soil,the pH,organic matter con⁃tent,available phosphorus content,available potassium content,and the number of cultivable fungi in the soil around Coptis chinensis roots were significantly increased.The total nitrogen content and total cultivable bacteria in the soil were significantly increased com⁃pared to the control soil on the whole.The nitrate nitrogen level significantly decreased compared to the control soil.The number of cul⁃tivable actinomycetes did not show significant changes on the whole.The number of soil prokaryotic microorganisms decreased,while the number of pathogenic fungi increased.
