Abstract

The invention discloses an edible fungus culture medium. The medium is composed of the following components: mulberry twig chips, walnut shell, peanut shell, edible fungus residues, oat residues, grosvenor momordica fruit residues, bamboo leaf residues, lime, gypsum, and additive; wherein the additive is composed of the following components in parts by weight: 20 to 25 parts of edible fungus extract, 10 to 20 parts of oat extract, 10 to 15 parts of grosvenor momordica fruit extract, 5 to 7 parts of bamboo leaf extract, 6 to 8 parts of chrysanthemum extract, 1 to 3 parts of sodium base bentonite, 0.3 to 0.5 parts of talcum powder, 0.1 to 0.3 part of magnesium sulfate, 0.2 to 0.4 part of calcium sulfate, 0.1 to 0.3 part of zinc sulfate, 0.01 to 0.03 part of sodium selenite, and 0.2 to 0.4 part of potassium dihydrogen phosphate. The raw materials are fully utilized, the culture medium can provide nutrients and also has a certain antibacterial function, and thus the edible fungus yield and polysaccharide content are both improved.

Description

technical field [0001] The invention relates to a fungus culture substrate, which belongs to the technical field of edible fungus production. Background technique [0002] Fungus, also known as black fungus and light fungus, belongs to Basidiomycetes, Auricularia, Agaricaceae, and is a kind of edible fungus that Chinese people often eat. It is flat in nature and sweet in taste, and has the effects of nourishing yin and strengthening, nourishing blood and promoting blood circulation, improving human immunity, and reducing arteriosclerosis. This is due to the fact that it contains protein, fat, polysaccharides, calcium, phosphorus, iron and other elements, as well as carotene, vitamin B1, vitamin B2, niacin, phospholipids, sterols and other nutrients, as well as a variety of essential amino acids. In recent years, as people's demand for fungus has increased rapidly, researchers have gradually focused their research on the culture medium of fungus. [0003] At present, the fu...
