Method for cultivating wild-like dendrobium officinale with high survival and cold resistance properties

Abstract

The invention discloses a method for cultivating wild-like dendrobium officinale with high survival and cold resistance properties. The method comprises the steps that 3-5 clusters of dendrobium officinale tissue culture seedling are put into a culture bottle for rooting culture and hardening-seedling, the root of a dendrobium officinale seedling after hardening-seedling is tied to the trunk of aliving tree by using a straw rope or a hemp rope for planting, and then a culture medium fertilizer is twined on the root of the dendrobium officinale; after cultivation is carried out for 25-35 days,topdressing is carried out, a speedling leaf fertilizer is diluted into 500 times of nutrient liquid fertilizer, and harvesting is carried out after maturity. The culture medium fertilizer comprisesan anti-freezing nutrition solution and a water-retaining agent. The anti-freezing nutrition solution comprises bamboo leaves, folium Ilicis cornutae, holly herb, folium photiniae, chinese box twig, Chinese loropetalum herb, saccharose, motor vehicle antifreeze fluid and preservative. The method for cultivating the wild-like dendrobium officinale with the high survival and cold resistance properties has the advantages that a basic living environment needed to be shady, cool, moist, air-permeable suitable for the growth of the wild dendrobium officinale is created, the anti-freezing and cold-proof abilities are improved, the survival rate is improved, the yield is high, the quality and taste of the dendrobium officinale are ensured, thereby being conductive to the industrialized, large-scale, artificial wild-like cultivation and production of the dendrobium officinale.

Description

technical field [0001] The invention relates to the technical field of dendrobium candidum cultivation, in particular to a cultivation method for imitating wild dendrobium officinale with high survival and cold resistance. Background technique [0002] Dendrobium officinale is the second largest genus of herbaceous plants in the family Orchidaceae. Dendrobium candidum has unique medicinal value. Modern medical research shows that the active ingredients of Dendrobium candidum include polysaccharides and alkaloids, which can significantly and effectively improve the immune function of the human body. Dendrobium officinale is one of the most precious Chinese herbal medicines in my country. [0003] Wild Dendrobium candidum only grows in the shady crevices on the cliffs or on the big trees in the virgin forest, and the requirements for the temperature, humidity, light and other microclimates of the growth environment are almost harsh. Its reproduction is difficult, the reproduc...

Problems solved by technology

At present, Dendrobium officinale is mainly cultivated artificially, and the quality is uneven. This cultivation mode is prone to various diseases and insect pests and breeds various germs, with low survival rate and no frost resistance.

In addition, due to the lack of a natural environment, the quality of Dendrobium officinale products is low, and the taste also lacks the fragrance of wild Dendrobium officinale
