Dendrobium officinale cultivation technology

Abstract

The invention relates to dendrobium officinale cultivation technology, wherein a greenhouse is established; a light reflecting film is covered by section on the greenhouse top; a seedbed is built inside the greenhouse; substrate is set on the seedbed; tissue-cultivated seedlings of dendrobium officinale are firmly planted in the substrate; after the seedlings are firmly planted, the day temperature inside the greenhouse is maintained between 25 DEG C to 35 DEG C and the humidity is controlled between 70 percent to 85 percent; and after the seedlings are firmly planted, the light is controlled by section. According to the invention, the technology steps are simple; the production cost is low; various nutrition contents in the obtained dendrobium officinale is relatively high and the efficacy is good; the light to the dendrobium officinale is controlled by section and the temperature is controlled collaboratively, so the height of a dendrobium officinale plant and the soluble protein content are significantly improved; the metabolism intensity and the reproduction rate of the dendrobium officinale plant are increased; and the polysaccharide content in the dendrobium officinale can arrive at 18 percent, thus the medical value of the dendrobium officinale is greatly increased.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a cultivation technique of Dendrobium candidum. Background technique [0002] Dendrobium is a traditional precious Chinese herbal medicine in my country, which is recorded in all previous editions of Chinese Pharmacopoeia. The original plant of the traditional Chinese medicine Dendrobium is a perennial herb of the genus Dendrobium in the family Orchidaceae. Dendrobium is one of the largest genera of Orchidaceae. There are more than 1,000 species in the world. There are 74 species and 2 varieties of Dendrobium plants in my country, of which more than 50 species are in commercial circulation. Among them, Dendrobium candidum is the most precious and the best of all Dendrobium. Dendrobium candidum is an endangered species and belongs to the second-class national key protected plant. , also known as "life-saving fairy grass" among the people. The authentic Dendrobium ...

Among them, Dendrobium candidum is the most precious and the best of all Dendrobium. Dendrobium candidum is an endangered species and belongs to the second-class national key protected plant. , also known as "life-saving fairy grass" among the people. The authentic Dendrobium candidum is iron green, has a slight smell, is sticky when chewed, sweet, and has little residue. Germination and long-term excavation have led to the depletion of wild Dendrobium candidum resources. Therefore, in recent years, many researchers have continued to explore the tissue culture and artificial planting of Dendrobium candidum. Although some achievements have been made, there is still a process of transplanting tissue cultured seedlings. The problems of low survival rate, slow growth, low yield, and short-term harvest of Dendrobium nutrient components have seriously restricted the industrialization and large-scale development of Dendrobium.
