American ginseng ( Panax quinquefolium L.) is a perennial plant that cultivated for medicinal purposes. Unfortunately, outbreaks of root rot disease in (AG) reduce yields and result serious economic losses. Information on the dynamics soil microbial communities associated with healthy diseased AG different ages limited. The present study explored differences field community structure, composition, interaction, their predictive functions at growth ages. Changes physicochemical properties were also examined to determine possible reasons outbreaks. Results revealed years, genera soil-borne pathogens, such as Alternaria , Botrytis Cladosporium Sarocladium Fusarium increased samples comparison those samples. In contrast, abundance some key potentially beneficial microbes, Bacillus Chaetomium Dyella Kaistobacter Paenibacillus Penicillium Trichoderma was decreased. Additionally, plants age, relative symbiotic fungi tended decrease, while potential pathogenic gradually increased. Various properties, available phosphorus, ratio total nitrogen phosphorus (N/P), pH, significantly P < 0.05) composition. Our findings provide scientific basis understanding relationship among well corresponding properties.
