Black fungus culture medium and preparation method thereof

Abstract

The invention discloses a black fungus culture medium and a preparation method thereof, and belongs to the technical field of the cultivation of edible mushrooms. The black fungus culture medium is prepared by adopting the following raw materials by weight percent: 30 to 48 percent of corncob powder, 15 to 36 percent of peanut shell powder, 18 to 25 percent of cottonseed hull powder, 10 to 15 percent of mallee bark chippings, 6 to 17 percent of wheat bran, 3 to 8 percent of bitter buckwheat husk, 1.5 to 3.2 percent of traditional Chinese herbal extraction liquid, 1 to 1.5 percent of gypsum powder, 0.6 to 1.4 percent of brown sugar and water added under stirring until the water content is 48 to 60 percent. By adopting the black fungus culture medium, the problems that the existing culture medium is unreasonable in nutritional structure, susceptible to the infection of bacteria, low in yield and poor in quality can be effectively solved, and the growth of bacteria and insect pest can be effectively controlled; moreover, the black fungus is good in quality and taste, the yield of the black fungus is increased, and the economic benefit of the planters can be increased.

Description

technical field [0001] The invention relates to the cultivation technology of edible fungi, in particular to a black fungus culture material and a preparation method thereof. Background technique [0002] Fungus, also known as black fungus, light fungus. Mycological classification belongs to Basidiomycetes, Auricularia, Agaricaceae. The color is dark brown, the texture is soft, the taste is delicious, the nutrition is rich, and it can be vegetarian or meat. Has many medicinal effects. [0003] At present, most of the black fungus on the market adopts artificial cultivation technology. Because the black fungus has strict requirements on external conditions such as temperature and humidity, the yield of the fungus is low. Crushed straw, bran, minerals, etc. are packed into special high-temperature-resistant plastic bags. At present, the ingredients of most of the culture materials of black fungus are unscientific and the nutritional structure is unreasonable. They are easy...
