Oyster mushroom culture medium prepared from corn flour and wheat bran

Abstract

The invention discloses an oyster mushroom culture medium prepared from corn flour and wheat bran. The oyster mushroom culture medium is prepared from the following raw materials by weight: 70-90 kilograms of corncobs, 7-13 kilograms of corn flour, 8-13 kilograms of wheat bran, 0.6-1.4 kilograms of lime, 0.7-1.2 kilograms of gypsum and 110-140 kilograms of water. A preparation method comprises the following steps: A, pulverizing the lime and the gypsum, and screening the lime and the gypsum through a sieve of 120 meshes to prepare lime powder and gypsum powder; B, pulverizing the corncobs into granules of which the diameters are smaller than 6mm, wherein 40 percent of the granules of which the diameters are 4-6mm are contained in the granules; C, performing mixing treatment: (1) uniformly mixing the pulverized corncob granules, the corn flour, the wheat bran, the lime powder, the gypsum and 130 kilograms of the water, and uniformly stirring to enable the water to thoroughly penetrate into the powder, and (2) putting the mixture consisting of the corncob granules, the corn flour, the wheat bran, the lime powder, the gypsum powder and the water into a bag, sealing the bag, heating the bag in a pot under 100 DEG C for 1-2 days, taking out the bag from the pot, cooling the bag to 30 DEG C, and then inoculating strains.

Description

technical field [0001] The invention relates to a medium for oyster mushrooms made of corn flour and wheat bran, which is mainly a medium for cultivating oyster mushrooms made of leftovers produced in agricultural production and corn flour and wheat bran. Background technique [0002] In the production of edible fungi, rice bran, rice bran, cottonseed hulls, and corncobs are routinely used as main ingredients to prepare culture media. Rice bran, rice bran, and cottonseed hulls are used as the main ingredients. They contain low nutrient organic matter, and corn flour, bran and other grains or concentrated feeds are often added. When grain and concentrated feed are added, chemical fertilizers such as urea are often added. The mushrooms produced have low nutritional content, poor quality, and poor taste. After years of research and more than two years of practice, I have successfully created a high-quality culture medium, which not only has high quality but also saves grain an...
