Flammulina velutipes medium and preparation method thereof

Abstract

The invention discloses a flammulina velutipes medium, which is composed of palm fiber, rice straw, potato starch, glycerol, ethylene glycol, a 5-8wt% NaOH solution, peanut shell, humic acid powder, plant ash, Chinese medicine residue, sodium alginate, soybean powder, citric acid, amino acid, mushroom residue, fish oil and water. The invention utilizes the principle of liquid fermentation, organic matters are firstly subjected to fermentation, the fermentation broth is rich in nutrition, and can quickly be absorbed by flammulina velutipes. The flammulina velutipes medium also contains straw fiber, and belongs to a fibrous matter with good toughness and strong water absorption after structural treatment, and can be used cooperatively with the added liquid nutritional components to play a storage role, and high toughness endows the medium with a good structural framework, and the medium can still maintain a fluffy state after a long time. The medium provided by the invention is suitable for use as a flammulina velutipes medium.

Description

technical field [0001] The invention belongs to the technical field of edible fungus culture medium, and in particular relates to a culture medium of Flammulina velutipes and a preparation method thereof. Background technique [0002] Edible fungi generally include fruiting bodies and mycelia, which are composed of eukaryotic microorganisms. Under a suitable growth environment such as sufficient nutrition and no restrictions on the individual, the individual will multiply rapidly, resulting in a substantial increase in the number, but when the number of fungi When it is increased to a certain amount, a mycelium composed of fungi will be formed. The dense mycelium is restricted by each other, and the directional formation of the fruiting body primordium is formed by the dense mycelium, which will later produce spores for sexual reproduction. Organs, while the mycelium is composed of tube-shaped cells that absorb nutrients, presenting a fluffy shape with well-branched branches...

AI Technical Summary

Problems solved by technology

[0004] Most of the traditional media are rice straw, rapeseed, wheat, sesame and other straws that are directly crushed and added, or added after simple fermentation. Such straws are mostly composed of dried mesophyll tissues and vascular bundles composed of internal fibers. The fibers themselves Although it has a certain degree of toughness, if it is used as a compost for long-term fermentation, it will be decomposed and utilized quickly, and the toughness function of the straw itself will soon be lost. The fluffy compost can improve the aeration performance of the medium, which is especially the case. important

However, during the use of the compost, the deposition of water often causes the medium to harden after a period of time. After accumulation to a certain extent, it is easy to breed bacteria and rot, which affects the growth of edible fungi.
