摘要：Background Pinellia ternata (Thunb.) Breit. is a widely used medicinal herb in traditional Chinese medicine, but continuous cropping obstacles hinder its sustainable development.Methods This pot study compared first cropping (FC) and one-year continuous cropping (CC1) of P. ternata, examining soil physicochemical properties, enzyme activities, and rhizosphere microbial communities at maturity stage to identify key factors underlying these obstacles.Results CC1 significantly reduced available potassium (AK,-18.03%), nitrate nitrogen (NO3 --N,-19.05%), ammonium nitrogen (NH4+-N,-10.88%), and dehydrogenase activity (S-DHA, -29.08%), while increasing total carbon (TC, + 24.80%) and catalase activity (S-CAT, + 22.14%). Compared with FC, CC1 decreased the relative abundance of beneficial fungus Mortierella by 90.24% and increased pathogenic Fusarium by 365.16%. Heatmap analysis indicated that P. ternata growth was primarily influenced by AK, NO3 --N, NH4+-N, and S-DHA, suggesting nutrient depletion and reduced enzyme are key factors leading to the observed yield decline. Mantel analysis showed that soil environmental factors significantly influenced the composition of fungal communities, whereas no significant correlation was found between bacterial communities and environmental factors. At the phylum level, continuous cropping reduced the abundance of bacterial Proteobacteria by 9.35%, while that of Acidobacteria increased by 25.37%. In terms of fungal community composition, continuous cropping decreased the abundances of Ascomycota and Mortierellomycota by 53.54% and 84.02%, respectively. Pearson correlation analysis showed that Ascomycota, Mortierellomycota and Rozellomycota were strongly correlated with S-CAT, S-DHA, AK, NO3 --N, and NH4+-N., whereas Rozellomycota showed the opposite pattern.
