Industrial cultivation method for dendrobium candidum

Abstract

The invention discloses an industrial cultivation method for dendrobium candidum, belonging to the technical field of Chinese herbal medicine cultivation. The industrial cultivation method disclosed by the invention comprises the following steps of: taking freshly wild dendrobium candidum seeds as a raw material, thereby obtaining a dendrobium candidum sterile cultivating system; the industrial cultivation method comprises related technologies, such as seed treatment, seedling propagation, seedling tissue-cultivation and seedling training, transplantation and the like, so that the source of the dendrobium candidum seedlings and the geo-authentic character of the seedlings are effectively ensured; compared with the conventional seedling propagation, the seedling propagation speed is increased by 37%, the seedling training and transplantation survival rates are increased to above 90%, and the yield is increased by above 30%; and compared with the active ingredient content of wild dendrobium candidum, the dendrobium candidum, cultivated according to the method disclosed by the invention, comprises a same polysaccharide content as the wild dendrobium candidum, and slightly higher amino acid content as well as trace-element content than the wild dendrobium candidum.

Description

technical field [0001] The invention relates to a cultivation method of the medicinal plant dendrobium officinale, in particular to a factory cultivation method of the dendrobium officinale. Background technique [0002] Dendrobium candidum is an excellent variety of Dendrobium, also known as black knot grass, which is a perennial epiphytic herb of Orchidaceae. Dendrobium candidum has unique medicinal value. Its stems are used as medicine. The name of Chinese medicine is Dendrobium. . The tender stems of a few varieties such as Dendrobium candidum are twisted into spiral or spring shape, and dried in the sun. The commercial product is called Dendrobium candidum, also known as Fengdou. Over the years, due to the destructive excavation by the farmers in the production areas, the wild Dendrobium officinale resources are on the verge of extinction, and the country has listed it as a national second-class protected plant endangered Chinese herbal medicine. [0003] In recent y...

AI Technical Summary

Problems solved by technology

These three methods of industrial production are group cultivation of seedlings is the best, but the current tissue culture technology of Dendrobium officinale is not yet mature, improper management and other problems lead to slow propagation speed of seedlings, low survival rate of tissue culture seedling hardening and transplanting

[0005] 2. Dendrobium officinale has slow growth rate, low yield and low active ingredient content

For example, when Dendrobium candidum is artificially planted, it fails to apply enough base fertilizer and top dressing, and fails to control the temperature and humidity well, which will cause its growth rate and output to fail to keep up, and even cause some diseases and insect pests, etc.
