【摘要】 [Objective] Based on GAP authentication, the standardized cultivation of Chinese traditional medicine Platycodon grandiflorum (Jacq.) A. in North China was studied in order to ensure the medicinal plants from the source. [Method] The best harvest time of Platycodon grandiflorum (Jacq.) A. was confirmed, and the pollution-free precautionary method of controlling Seedling Blight and Leaf Spot was obtained. [Result] The results showed that the best harvest time of Platycodon grandiflorum (Jacq.) A. was in the second ten days of September when the cool and dry climate was convenient for the post-processing. It had good effects of applying 75% 0.7 g/L Jubang ultramicro wet powder and 50% 1.4 g/L Carbendazim WP ultrafine powder simultaneously to control Seedling Blight and Leaf Spot of Platycodon grandiflorum (Jacq.) A.. [Conclusion] The study has laid the theoretical basis for high-yield cultivation of Platycodon grandiflorum (Jacq.) A. .
