Study the growth and development process of rhizomes(bamboo-like part) of Notopterygium incisum and the changes of carbohydrate, endogenous hormones and secondary metabolites, and provide theoretical guidance for the formation of high-quality N. incisum medicinal commodities under artificial cultivation. The One-year-old seedlings were transplanted to the original habitat,and the growth and physiological characteristics of N. incisum were dynamically monitored. The results showed that: ① Seedlings transplanted to the original habitat in spring could form rhizomes(bamboo-like part) in the same year. ② After 60 days of transplantation, the root length and root diameter of underground part of N. incisum had increased rapidly, and carbohydrate content in roots and rhizomes had accumulated rapidly. After 120 days of transplantation, the roots and rhizomes of underground part had grown slowly, and starch content in roots and rhizomes increased continuously, while sucrose and total soluble sugar content decreased gr
