Impact of various intercropping modes on soil quality, microbial communities, yield and quality of Platycodon grandiflorum (Jacq.) A. DC.
Abstract Introduction Intercropping has the function of promoting plant growth, improving yield and quality. Platycodon grandiflorus (P. grandiflorus) is a traditional Chinese medicinal herb; continuous cropping obstacles significantly inhibit its yield and quality. However, few study have establish...

| description | Abstract Introduction Intercropping has the function of promoting plant growth, improving yield and quality. Platycodon grandiflorus (P. grandiflorus) is a traditional Chinese medicinal herb; continuous cropping obstacles significantly inhibit its yield and quality. However, few study have established about P. grandiflorus interaction of various crops. This study provides a theoretical foundation to explore the most effective intercropping method, enhance soil utilization efficiency, and increase the yield and quality of P. grandiflorus. We conducted field experiment, P. grandiflorus monoculture (JG-JG), P. grandiflorus and Achyranthes bidentata intercropping (JG-NX), P. grandiflorus and Saposhnikovia divaricata intercropping (JG-FF), P. grandiflorus and Glehnia littoralis (JG-SS) intercropping. Additionally, we included three main intercropping crops with P. grandiflorus, Zea mays (JG-YM), Setaria italica (JG-GZ), and Glycine max (JG-DD). The soil physicochemical properties, enzyme activity, soil microorganisms, the yield and secondary metabolite content in the roots of P. grandiflorus were determined. The results showed that intercropping significantly increased the yield and quality of P. grandiflorus, and significantly reduced the incidence rate of root rot. The intercropping system enhances the physical and chemical properties of soil, soil enzyme activity, and soil microbial diversity. JG-SS intercropping significantly increased the abundance of bacteria and fungi, stimulated soil microbial communities, promoted plant growth, significantly increased yield and content of platycodin D, enhanced the complexity of microbial co-occurrence networks. This study could provide a sustainable planting system for the cultivation of P. grandiflorus, particularly the system JG-SS. Clinical trial number Not applicable. |
