Soil acidification and nutrient imbalance mediate fungal community degradation, a key driver of continuous cropping obstacles in <i>Platycodon grandiflorus</i>.

ABSTRACT:

Introduction

Continuous cropping obstacles severely restrict the sustainable cultivation of Platycodon grandiflorus. This study aimed to clarify the key drivers underlying these obstacles, focusing on the roles of soil physicochemical properties and rhizosphere fungal community dynamics.

Methods

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.

Results

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 Fusariu
