The method of cultivating Gastrodia elata outdoors in the northern region

Abstract

The invention discloses an outdoor tall gastrodia tuber cultivating method in northern area. The method comprises the technical processes of land selection and pit opening, wood preparation, preparation of two bacteria and one seed, sowing, cultivation management, harvesting and the like, and in particular an antifreezing cultivation management technique and a two-bacteria and one-seed once sowing technique; the outdoor tall gastrodia tuber cultivating method is feasible and unique. An apricot tree land is taken as a planting base, the trimmed branches and leaves of the apricot trees are taken as a planting material for the tall gastrodia tubers, tall gastrodia tuber pits are formed in the open spaces in the apricot tree land, and therefore, intercropping of Chinese medicinal herb and forest and stereo planting are realized; as a result, the outdoor tall gastrodia tuber cultivating method has important practical significance for returning farmland to forests and increasing the income of farmers in the northern area. Besides, according to the tall gastrodia tuber cultivating method, the wood utilization rate is high, the tall gastrodia tubers are high in quality and relatively high in various nutrition ingredients, and the medicinal effect of the tall gastrodia tubers can be comparable with that of wild tall gastrodia tubers.

Description

technical field

[0001] The invention belongs to a medicinal material cultivation method, in particular to a method for outdoor cultivation of Gastrodia elata in the northern region. Background technique

[0002] Gastrodia elata is a mycorrhizal orchid plant without roots and green leaves, and cannot perform photosynthesis to produce nutrients for its own growth. Gastrodia elata must be symbiotic with germination bacteria and Armillaria mellea, that is, gastrodia elata Embryo growth (early growth) depends on germination bacteria. When the embryo is formed, it must live in symbiosis with Armillaria. During its growth, it provides nutrition through Armillaria.

[0003] Modern medical research shows that the functions of the active ingredients of gastrodia elata mainly include: dispelling wind and relieving spasm, relieving pain, anti-epilepsy, and mainly treating "dizziness, headache, high blood pressure, rheumatic waist and knee pain, numbness of limbs, epilepsy in children, c...
