Description
Technical Field
The invention relates to the technical field of traditional Chinese medicine cultivation, and particularly relates to a wild planting method of dendrobium.
Background
The dendrobium is one of the traditional Chinese medicine health preserving products with the longest history in China, has records about dendrobium in the earliest existing pharmaceutical work 'Shennong Ben Cao Jing' in China, is popular as a superior good medicine for 'tonifying internal organs and consumptive disease, emaciation, reinforcing yin, thickening intestines and stomach, lightening and prolonging life' by the famous medical doctors in the past, and has extremely high medicinal value. Modern medical research proves that: the dendrobium contains various trace elements, polysaccharide, alkaloid, amino acid and the like which are necessary to human bodies, has the effects of improving the immunologic function, inhibiting thrombosis, inhibiting tumors, resisting aging and the like, and is widely applied to Chinese patent medicines and health-care products.
Dendrobe (Dendrobium) is one of the more diverse genera of Orchidaceae (Orchidaceae) plants, about 1000 species are in the world, 74 and 2 varieties are in China, wherein the medicinal and health-care values of Dendrobium nobile (Dendrobium nobile) and Dendrobium officinale (D.officinale) are the highest, and the market demand is rising year by year. For years, due to the unregulated mining of people and the low natural reproduction rate, the natural resources of dendrobium nobile and dendrobium officinale are gradually exhausted and are positioned at the edge of imminent extinction, and the dendrobium nobile and dendrobium officinale are listed as wild medicinal material varieties with key protection in national regulations on the protection and management of wild medicinal material resources, and the mining is forbidden at present. Most of dendrobium circulating in the market is artificial cultivated varieties.
At present, the artificial cultivation of the dendrobium in China mainly adopts greenhouse planting, tree hanging planting and stone building planting. Many planters plant the dendrobium in a wild environment simulation mode, aiming at improving the quality and medicinal value of the dendrobium, but the dendrobium needs to be watered and fertilized regularly in the planting process, so that the real wild dendrobium cannot be cultivated, and the management energy and planting cost of the planters are increased; moreover, in the existing planting process of hanging the dendrobium on the tree or building stones, due to the imperfect stone building technology and the low tree hanging technology, the survival rate of the dendrobium is low, and the growth vigor of the dendrobium is weak.
