[Objectives] To investigate the effects of three cultivation methods-level bed, high ridge, and ridge cultivation-on the yield and quality of Radix scutellariae, providing a basis for establishing its Good Agricultural Practice (GAP) technical system. [Methods] Utilizing two-year-old R. scutellariae plants from the cultivation base in Kushan Township, Ju County as the experimental material, yield-related indicators including root length, root diameter, branch number, and fresh weight were measured at harvest time. The baicalin content in the roots was determined using High-Performance Liquid Chromatography (HPLC), and the differences in effects among the cultivation methods were analyzed. [Results] R. scutellariae cultivated using the ridge method exhibited significantly superior root length compared to both level bed and high ridge cultivation. Its branch number was significantly higher than that under level bed cultivation. The baicalin content reached 13.17%, surpassing that achieved with high ridge (12.73%) and level bed (11.87%) cultivation. Based on a comprehensive evaluation of agronomic traits and active constituent content, R. scutellariae cultivated using the ridge method demonstrated significant superiority in both yield and quality over those grown under high ridge or level bed conditions. [Conclusions] Ridge cultivation effectively promotes root growth in R. scutellariae, enhances medicinal material yield and baicalin content. This method is recommended for widespread application in artificial cultivation and provides a scientific foundation for establishing R. scutellariae GAP standards. |
