This study analyzed the growth indicators of Platycodon grandiflorus, soil physicochemical properties, and the characteristics and functions of fungal communities under different durations of continuous cropping years to explore the impact of continuous cropping on its growth and rhizosphere microecology. Continuous cropping significantly inhibited the growth of Platycodon grandiflorus. As the continuous cropping years continued, root length, root diameter, yield, and alcohol-soluble extract content decreased, the abundance of Fusarium increased, and root rot was exacerbated. Continuous cropping led to soil acidification, reduced phosphorus and potassium contents, and an imbalance of the fungal community; the abundance of acid-tolerant pathogens increased while beneficial fungi decreased in abundance, with pathotrophic and saprotrophic fungi enriched, resulting in slowed soil carbon turnover and reduced disease resistance. These findings suggest that adjusting soil pH, increasing phosphorus and potassium fertilization, and inoculating functional fungal agents can alleviate continuous cropping obstacles, providing an empirical basis for the sustainable development of the Platycodon grandiflorus industry.
