Edible fungus medium and preparation method thereof

Abstract

The invention belongs to the domestic fungus cultivation technical field, and especially relates to an edible fungus medium and a preparation method thereof; the edible fungus medium is formed by thefollowing raw materials by weight parts: 60-70 parts of cob, 65-75 parts of Cinnamomum camphora wooden chips, 5-8 parts of TCM powders, 20-25 parts of vinasse, 30-35 parts of bagasse, 2-4 parts of lime and proper amount of plant ashes; various raw materials are decocted and fermented so as to allow the edible fungus to fast and fully absorb the nutrients in the raw materials, thus improving the growth speed, and increasing the yield. By using the edible fungus medium of the method to culture edible fungus, the obtained edible fungus is low in a competitor pollution rate, fast in growth speed,and high in yield.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, in particular to a fungus culture medium and a preparation method thereof. Background technique [0002] Fungus, also known as wood fungus, light fungus, tree ear, belongs to the fungus phylum, stratomycetes, and genus Auricularia, parasitizes on damp and decayed trees, and mostly grows on more than 120 kinds of broad-leaved trees such as oak, poplar, banyan, and locust tree On rotten wood. Fungus is sweet in taste and flat in nature, mainly containing protein, polysaccharide, calcium, iron, carotene, B vitamins and other nutrients. Anemia, thrombosis, coronary heart disease, etc.; can nourish the blood and keep the face, making the skin rosy and radiant; can dredge the stomach, lubricate the intestines, etc. [0003] China is the main producer of fungus, and the production areas are mainly distributed in Jilin, Heilongjiang, Yunnan, Guizhou, Sichuan and other places. Fungus ...

AI Technical Summary

Problems solved by technology

Fungus is also one of the main export edible fungi in my country. At present, large-scale and bag-based cultivation have been realized, but there are problems of large contamination of bacteria, slow growth and low yield.

Therefore, many scholars have carried out relevant research on the fungus culture medium, and many culture media with antibacterial functions have appeared, which solved the problem of bacterial contamination in the fungus culture process, but there is still the problem of slow growth.

Such as the patent application number 201710699790.0 discloses a fungus culture material and a method for cultivating fungus, using sawdust, corn cobs, grain residues, grains, antibacterial powder, and inorganic additives as raw materials to obtain the fungus culture material by mixing evenly, just by simply The various nutrients in the raw materials cannot fully penetrate into the culture material and cannot interact with each other. Therefore, the fungus cannot absorb nutrients from the culture material in time, thus affecting its growth rate.
