Production and application technology of symbiotic armillaria mellea artificial fungus stick for Gastrodia elata Bl.

Abstract

The invention discloses a production and application technology of a symbiotic armillaria mellea artificial fungus stick for Gastrodia elata Bl., and belongs to the technical field of Chinese medicinal plant planting. The technology mainly comprises the following steps: (1) preparation of raw materials of an armillaria mellea artificial fungus stick, and mixing; (2) production of the armillaria mellea artificial fungus stick and sterilization; (3) inoculation of the sterilized armillaria mellea artificial fungus stick and cultivation; (4) field use of the cultivated armillaria mellea artificial fungus stick and Gastrodia elata Bl. planting. Compared with the conventional Gastrodia elata Bl. planting technology, the technology has the advantages that agricultural waste is adopted to produce the symbiotic armillaria mellea artificial fungus stick for Gastrodia elata Bl., industrialized production can be carried out, the operation step of culturing a fungus bed or fungus stick 6 to 8 months before Gastrodia elata Bl. planting in the conventional technology can be eliminated effectively, the traditional planting period is shortened, the inoculation rate and the Gastrodia elata Bl. yield after white-head Gastrodia elata Bl. permanent planting can be improved effectively, earlier-stage growth nutrition feeding can be guaranteed, the Gastrodia elata Bl. yield can be improved greatly, and the use of natural fungus materials can be replaced and greatly reduced, so as to reduce damage to natural woods of Gastrodia elata Bl. planting, and protect the ecological environment.

Description

technical field [0001] The invention belongs to the technical field of planting traditional Chinese medicinal materials, and in particular relates to a technique for making and applying an artificial fungus stick of Gastrodia symbiotic Armillaria mellea. Background technique [0002] Gastrodia elata (Gastrodiaelata Bl.) is a perennial herb of the Orchidaceae Gastrodia genus. It is a commonly used and precious traditional Chinese medicine. It has been used as medicine and edible history for more than 2,000 years. Gastrodia elata is a very simplified orchid plant. It has no roots and no green leaves. It must live in symbiosis with Armillaria armillaria. It can only grow and reproduce after digesting Armillaria armillaria. Gastrodia elata cannot grow without Armillaria armillaria. Armillaria armillaria mainly rely on broad-leaved tree segments to provide nutrition. The wood used to cultivate Armillaria elata is called fungus material. The commonly used tree species suitable f...

Problems solved by technology

This conventional cultivation method needs to cultivate the fungus bed or fungus stick in advance, which is time-consuming and laborious, and also causes a great waste of wood

In recent years, some Gastrodia elata production areas have adopted the cultivation method of three nests, which is a cultivation method in which the three main materials for propagating Gastrodia elata (wood, Armillaria cultivars, and Gastrodia elata seeds) are placed in the cultivation holes at the same time. Cultivate fungi, but because the time left for Armillaria mellea to grow before the germination of Gastrodia elata is limited, the new tubers often do not receive sufficient nutrient supply, resulting in failure of Gastrodia elata planting or low yield of Gastrodia elata

[0004] In the patent of a fungus stick used in the cultivation of Gastrodia elata (application number: 201110102592.4), it is disclosed that any one or several kinds of sawdust, branches and leaves or bark waste of broad-leaved trees are crushed and formed by pressing. The fungus sticks used in Gastrodia elata cultivation do not need to cut down forest resources at the cost of promoting Gastrodia elata planting, avoiding the destruction of forest resources in traditional Gastrodia elata planting areas, and the occurrence of increasingly scarce effective resources, but its production The process needs to be pressed into a round wooden stick with a diameter of 5cm to 20cm at a temperature of 80° to 300° and a pressure of 10 to 30 MPa. However, the production process requires high requirements and the equipment process is complicated.
