Abstract

Abstract: 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 community structure of these soil samples were analyzed. The results showed that, compared to the control soil, the pH, organic matter content, 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 compared to the control soil on the whole. The nitrate nitrogen level significantly decreased compared to the control soil. The number of cultivable actinomycetes did not show significant changes on the whole. The number of soil prokaryotic microorganisms decreased, while the number of pathogenic fungi increased.

Key words: Coptis chinensis Franch, physicochemical factors, microbial group, natural state, soil environment, correlation analysis
