Soil microbiome dysbiosis and rhizosphere metabolic dysfunction drive continuous cropping obstacles of <i>Codonopsis tangshen</i>.

ABSTRACT: Successive monocropping of Codonopsis tangshen causes continuous cropping obstacles, impairing growth, yield, and quality. To investigate the soil environmental and microbial changes caused by these obstacles, we collected both continuous cropping (C-crop) and non-continuous cropping (NC-crop) soil for analysis. We employed high-throughput sequencing, Biolog-ECO microplate, and metabolomics technology to evaluate microbial diversity, community structure, and carbon source utilization efficiency. Compared with NC-crop, C-crop decreased the yield and polysaccharide content of C. tangshen by 40.47 and 29.4%, respectively. Continuous cropping significantly altered soil physicochemical properties and metabolomes, driving distinct shifts in microbial community structure and impairi
