Culture medium for improving bioconversion rate of edible fungi, preparation method of culture medium and cultivation method of edible fungi

Abstract

The invention provides a culture medium for improving the bioconversion rate of edible fungi, a preparation method of the culture medium and a cultivation method of edible fungi. The culture medium comprises the following raw materials: 40-70% of cottonseed hulls, 5-15% of corncobs, 1-8% of soybean meal, 10-20% of wheat bran, 5-20% of waste germ bran and 1-5% of calcium carbonate. The culture medium provided by the invention for cultivating edible fungi can apparently shorten fungi growing period, increase the yield, and greatly improve the quality and taste; meanwhile, the waste germ bran is added to reduce environmental pollution caused by abandoning the waste germ bran, also appropriately reduce the dosage of the cottonseed hulls and the wheat bran in ingredients, accordingly reduce preparation costs, and have certain economic applicability.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to an edible fungus culture medium capable of improving the biotransformation efficiency of edible fungi, a preparation method thereof and a cultivation method of edible fungi. Background technique [0002] Edible fungi refer to large edible fungi with large fruiting bodies, commonly known as mushrooms. There are more than 350 kinds of edible fungi known in China, most of which belong to Basidiomycotina. Cordyceps, truffles, lark and boletus, etc.; a few belong to the subphylum Ascomycota, including morels, saddle mushrooms, truffles, etc. [0003] At present, the total output and total export volume of edible fungi in my country have leapt to the first place in the world. The annual edible fungus cultivation waste, i.e. fungal chaff, is about 30 million tons. The traditional method of disposal is to discard or burn, which not only causes waste of reso...

AI Technical Summary

Problems solved by technology

[0003] At present, the total output and total export volume of edible fungi in my country have leapt to the first place in the world. The annual production of edible fungus cultivation waste, that is, mushroom chaff, is about 30 million tons. The traditional method of disposal is to discard or burn, which not only causes waste of resources, but also Also causes mold and pest growth, increases the number of harmful spores and pests in the air, pollutes the environment

[0004] At present, the medium used for cultivating edible fungi includes log cultivation, dung grass cultivation, and substitute material cultivation. Commonly used culture materials generally use cottonseed hulls, crop straw, wood chips, corn flour, soybean meal, and distiller’s grains as the main materials. For example, if cottonseed hulls are used as the medium, the raw materials need to be decomposed and reused so that the nutrients in them can be absorbed by edible fungi; if wood chips, bran, sugar and gypsum are used as raw materials, the price of sugar and bran is relatively expensive. Media costs are higher

[0005] On the whole, there are few organic edible fungus culture mediums that can achieve better quality, yield and high economic applicability, and the edible fungi produced by them have less effective ingredients for human health care, and the health care functions brought to the human body are also unsatisfactory.
