Scope: This standard specifies the technical content of seed preparation, pre-sowing preparation, post-sowing management, and archiving for the production of Stinky Ginseng seedlings in Yunnan. This standard applies to Stinky Ginseng seedling cultivation in Yunnan. It is suitable for areas with an altitude of 1,500m to 2,300m in Yunnan. Main technical content: 1. Terms and definitions: The following terms and definitions apply to this standard. 1.1 Stinky Ginseng (Codonopsis foetens Hook. f. et Thoms), also known as Stinky Partygen, Orchid Ginseng, and Hu Mao Yang Shen, belongs to the family Araliaceae and is a perennial, deciduous, slender vine plant.

Seed preparation 2.1 Seed selection: Select healthy plants without disease or pest infestation, and harvest fully mature and plump seeds. 2.2 Seed storage: After drying, store the seeds in a cool, ventilated, and dry environment. 2.3 Seed preparation: Select seeds with intact seed coats, free from disease or pest infestation, and a germination rate of ≥85%. 3. Pre-sowing preparation 3.1 Site selection: The site environment should meet the requirements of NY/T 391-2021. The seedling site should be a semi-shaded, semi-sunlit slope with a close proximity to water sources. The soil should be loose, fertile, rich in humus, and well-drained, with a sandy loam texture. The soil should comply with GB 15618-2018 standards, and the water quality should meet GB 5084-2008 standards. The site should be conveniently accessible, with a pH value of 5.5-6.5. 3.2 Land preparation 3.2.1 Site clearing: One month before sowing, remove plant residues, rotten leaves, root forks, weeds, and hardened soil clumps from the soil. 3.2.2 Deep plowing: After clearing the site, plow the soil to a depth of over 40cm and break it up. 3
