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.
