Method for producing halimasch strain by utilizing waste gastrodia elata fungi

Abstract

The invention belongs to the technical fields of production and reutilization of waste gastrodia elata fungi and in particular relates to a method for producing a halimasch strain by utilizing waste gastrodia elata fungi. The method comprises the following steps: S1, treatment of small waste gastrodia elata fungi; S2, treatment of a nutrient solution; S3, preparation of a composite nutrient solution; S4, treatment of a small fungi substrate; S5, inoculated culture of halimasch; S6, observation of cultural character of halimasch and determination of evaluation index; and S7, screening and determination of a preferred nutrient solution formula. The halimasch strain is produced by using the treatment method, so that a traditional method for producing the halimasch strain by utilizing fresh wood flour and branches is changed; and due to the replenishment of the nutrient solution, the reutilization of the waste gastrodia elata fungi on the production of the halimasch strain can be realized,the utilization ratio of wood resources is increased, and the cost of traditional halimasch strain production is reduced.

Description

technical field [0001] The invention belongs to the technical field of production and reuse of Gastrodia elata discarded fungus material, and in particular relates to a method for producing Armillaria strains by utilizing the Gastrodia elata discarded fungus material. Background technique [0002] Armillaria Armillaria is an important symbiotic fungus in the growth process of Gastrodia elata. The fungus decomposes cellulose and lignin in wood as nutrients for its own growth and development, and at the same time forms a certain symbiotic relationship with Gastrodia elata. Stage provides nutrients to ensure the normal growth and development of Gastrodia elata. Therefore, the cultivation of Gastrodia elata is inseparable from the excellent Armillaria strains. In the main producing areas of Gastrodia elata in Yunnan, the production of Armillaria strains has become an industry, and the investment in strains is one of the main costs in the cultivation process of Gastrodia elata. ...

AI Technical Summary

Problems solved by technology

At present, the production of Armillaria strains mainly uses cottonseed hulls, miscellaneous wood chips, and small pieces of fresh wood as the main materials. The transportation cost of cottonseed hulls in Yunnan is relatively high, and long-term dependence on fresh wood and miscellaneous wood chips as the main substrate increases forest ecological resources. protection pressure, the traditional Armillaria production method is not conducive to reducing the cultivation cost of Gastrodia elata and improving the planting profit of Gastrodia elata
