Method for culturing rhizome drynariae

Abstract

An artificial reproduction method for drynaria includes asexual production and spore reproduction. Said asexual reproduction includes such steps as taking its rhizome segment with 3-5 bud points and 3-5 sporophyllary leaves, fixing it to tree or mountain rock, covering it by bryophyte, spraying water and management. Said spore reproduction includes such steps as sterilizing the burnt earth, immersing in cold boiled water, loading the sporanges in bag, drying in air, preparing the suspension of sporanges, spraying it onto said burnt earth, optical culture to obtain gametophytes, transplanting, culturing to obtain sporophytes, and transplanting them on tree or mountain rock.

Description

technical field

[0001] The invention relates to a method for artificially planting the original plant of wild Chinese medicinal material Rhizoma Rhizoma Rhizoma Rhizome. Background technique

[0002] Oak fern [Drynaria fortunei (Kunze) J.Sm] is a plant of the genus Oak Fern in the family Oak Fern. It is a perennial epiphytic herb. The height of wild plants is 20cm-40cm. The rhizomes are thick and fleshy, long and horizontal. In mid-March, the rhizomes began to grow and extend, and the vegetative leaves grew and continued until June and July. From late May to July, the sporophylls gradually withered and withered. From the first ten days of August, the rhizomes began to grow and extend for the second time, and the sporophylls were in the shape of Fist shape begins to grow, and by mid-September, most of the sporophylls are fully stretched and grown, sporangia development begins in late September, and spores mature at the end of October. As the sour...
