Mother culture medium for facilitating growth of edible fungus mycelia

Abstract

The invention discloses a mother culture medium for facilitating growth of edible fungus mycelia. The mother culture medium comprises, by weight, 80 parts of corncobs, 10 parts of bran, 1 part of ureaand 5 parts of lime, and the ratio of material to water is 1:2.5. A preparation method of the mother culture medium includes the steps: firstly, accurately weighing the materials according to the ratio, and uniformly mixing the materials according to the material and water ratio of 1:2.5 to obtain mixture; secondly, building a fermentation material pile with the mixture acquired in the first step, and holing from the top to the bottom at intervals; thirdly, turning the fermentation material pile over, cooling, drying and crushing fermentation materials after mixture is completely fermented, and screening the crushed mixture to obtain dry mother culture medium. According to the mother culture medium, raw materials are low in cost and easily acquired, the mother culture medium has great significance for great improvement of resource utilization rate, mushroom production rate and labor productivity rate, a good production mode is provided for agricultural green development, and the mother culture medium is good in antibacterial effect and applicable to culture of various edible fungi.

Description

technical field [0001] The invention relates to the field of edible fungus cultivation, in particular to a mother seed culture medium for promoting the growth of edible fungus hyphae. Background technique [0002] Edible fungi are large edible fungi. There are more than 350 kinds of edible fungi known in China. At present, edible fungi such as Pleurotus eryngii, Pleurotus eryngii, and fungus have become must-have dishes on the public table due to their rich nutrition and moderate price, and have been widely cultivated around the world, such as China, Japan, India, Germany, South Korea, France and other major producing countries. [0003] In the cultivation technology of edible fungi, since the mother species of edible fungi (such as oyster mushroom, fungus, etc.) After the seed is transferred and expanded, it is inoculated into the bacteria bag or inoculation bottle. In the transfer expansion culture, the growth and growth speed of the mother species of mycelia directly a...

Problems solved by technology

These mediums need to purchase raw materials to boil and filter, which takes a long time. If you buy the configured dry powder medium, the price is extremely expensive, which increases the cost of Pleurotus ostreatus cultivation; and the bacteriostatic effect of these mediums is very poor, so boiling or When preparing the medium, it is often necessary to add antibacterial drugs to the medium to inhibit the germination or reproduction of miscellaneous bacteria such as mold or bacteria
