Artificial wild gastrodia elata cultivation technique

Abstract

The invention discloses an artificial wild gastrodia elata cultivation technique. The technique includes the following steps: collecting local wild fresh armillaria mellea mycelia, preparing primary mother strains in a test tube, and switching secondary solid strains; selecting loose loam, sandy loam good in drainage performance or sandy soil, wherein pH value of the soil is 5-6; preparing firewood for preparing mushroom sticks and mushroom branches; preparing a filling material; culturing the mushroom sticks; cultivating gastrodia elata. A mushroom stick culturing method and a gastrodia elata cultivating method are more suitable for growing of gastrodia elata; especially, in the cultivating process of the gastrodia elata, sophora flavescens powder or tobacco stem powder is utilized, so that the mycelia can be prevented from being eaten by insects; penicillin liquid is sprayed, so that mushroom contaminating and rotting can be prevented; the artificial cultivation technique of the gastrodia elata is enabled to be more scientific and more reasonable, and yield of the gastrodia elata is stable; product detecting shows that gastrodin content is 0.38%, and product requirements are met completely.

Description

technical field [0001] The invention relates to a plant cultivation technology, in particular to a technology for artificially cultivating wild Gastrodia elata. Background technique [0002] Gastrodia genus Orchidaceae and Armillaria symbiotic heterotrophic, perennial herb, its tubers are used for medicine. Gastrodia elata has no roots and leaves, and cannot produce nutrients by itself, nor can it absorb inorganic salts from the soil. The only way is to grow and reproduce by digesting and absorbing the Armillaria bacterium that has penetrated into the body as nutrition. Armillaria armillaria is a facultative fungus, it can parasitize and grow on more than 100 kinds of broad-leaved woods, it has a strong decomposing ability, it can parasitize dead trees for saprophytic life, and can also parasitize living tree roots to decompose wood fibers element, growth and reproduction. When encountering the mycelium of Armillaria Gastrodia, it will drill into the tuber of Gastrodia el...

Problems solved by technology

"Currently, most countries in the world do not produce Gastrodia elata, relying on purchases from China, Gastrodia elata is not only a rare and precious Chinese medicinal material, but also a traditional export commodity. Due to the limited production of wild Gastrodia elata, it cannot meet the market demand. Therefore, artificial Gastrodia elata cultivation technology has broad prospects

Existing techniques for artificially cultivating Gastrodia elata are mainly suitable for mountainous areas and plains, but are not suitable for hilly areas with dry climate and low temperature. According to the methods disclosed in the prior art, there has been no success so far in cultivating Gastrodia elata. One is that the mycelium is eaten by various insects, and the other is the phenomenon of rot, which has not been solved so far, which greatly affects the cultivation of artificially cultivated gastrodia elata
