Processing: removing impurities from Rhizoma Drynariae, washing, fully wetting, cutting into thick pieces and drying. Scald the Rhizoma Drynariae to obtain clean Rhizoma Drynariae or tablets, and iron them with sand according to the scalding method (Appendix II D) until they swell and get rid of hair. This product is the dried rhizome of Rhizoma Drynariae (Kunze) of Polypodiaceae. You can dig all year round, remove sediment, dry in the sun, and burn hair (scales).
breeding method
Propagation by ramets: Drynaria fortunei plants have fleshy and scaly rhizomes. Cut the rhizome of Drynaria fortunei into (10 2) cm segments, with 3-5 buds and 3-5 spore leaves in each segment, then fix it on trees or rocks, cover it with a little moss, and strengthen the management of water spraying. After about 2 months, new vegetative leaves and rhizomes will be produced.
The method of dividing plants is of certain significance to the protection of Rhizoma Drynariae resources, but it needs to be excavated nearby, the original root system should be as complete as possible, and the original habitat should be planted, so the propagation coefficient is low and it is not convenient to transport.
Spore reproduction: Spore reproduction is one of the effective ways to expand reproduction. The sporangium of Rhizoma Drynariae is round and has no capsule. Under natural conditions, its spore germination rate is low, and the requirements for gametophyte development, sexual organ development, fertilization and sporophyte growth are relatively high, which makes it difficult for Rhizoma Drynariae to reproduce naturally.
