Edible fungus culture medium using tea branches and tea stems as raw materials and preparation method of edible fungus culture medium

Abstract

The invention relates to the field of edible fungus culture, in particular to an edible fungus culture medium using tea branches and tea stems as raw materials and a preparation method of the edible fungus culture medium. According to the invention, the tea branches, the tea stems, tea leaf dust and tea leaves are used as main raw materials of the culture medium, tea resources are not utilized toprovide necessary growth elements of edible fungi, tea resources are not utilized to provide crude protein, crude fibers and tea polyphenol, and meanwhile, the culture cost of farmers is reduced; according to the invention, a large amount of fertilizers, nutritional ingredients, mineral substances and microorganisms required for growth of the edible fungi are provided through combination of earthworm manure, silkworm chrysalis powder, plant ash and chicken manure; according to the invention, by designing the Chinese herbal medicines, the effective components of the Chinese herbal medicines improve the disease resistance of the edible fungi and help the edible fungi resist nematode, mite and slug infection; and according to the invention, bacteria and fungi are killed through two modes of quick-freezing cooling and high-temperature sterilization, so that the edible fungus culture medium is ensured to be in a sterile state, and the growth environment of the edible fungi is ensured.

Description

technical field [0001] The invention relates to the field of edible fungus cultivation, in particular to an edible fungus culture medium using tea branches and tea stalks as raw materials and a preparation method thereof. Background technique [0002] In recent years, with the development of tea deep-processing technology and the development of tea deep-processing products, a large amount of tea resource waste has been produced, such as tea dregs, high-grade tea and tea product processing waste, low-grade tea, etc. A large number of discarded summer and autumn teas and pruned tea branches and leaves are produced. These unused tea resources not only brought serious pressure to the ecological environment, but also caused a huge waste of resources. There are still a lot of nutrients in these tea resources, for example, 17%-19% of crude protein, 16%-18% of crude fiber, 1%-2% of tea polyphenols remain in the extracted tea dregs. Phenol has high potential utilization value. How...
