Method for using mushroom culture medium

Abstract

The invention discloses a method for using a mushroom culture medium. The method comprises the steps: (1) mixing an appropriate amount of main material and an appropriate amount of auxiliaries, so as to form a mixture; (2) adding an appropriate volume of acetic acid to the mixture of the main material and the auxiliaries, so as to adjust the pH value to 5.5, and loading the adjusted acidic mixture into plastic bags; (3) sterilizing the mixture in a closed condition for 2.5 hours at the temperature of 50-80 DEG C, cooling the sterilized mixture, and then, inoculating the sterilized mixture with hericium erinaceus strains; and (4) carrying out culturing for 30-35 days at the temperature of 23-28 DEG C, then, transferring the cultured hericium erinaceus strains to a fruiting chamber, carrying out moisturizing fruiting, and carrying out harvesting 15-20 days later, thereby obtaining selenium-enriched hericium erinaceus. According to the method, the culture medium has the advantages that thallus growth is vigorous, the content of selenium in the hericium erinaceus is relatively high, the nutritive value of thalli is relatively high, the culture medium utilization efficiency of strains is high, the biotransformation ratio is high, the cost is reduced, and the economic benefit for hericium erinaceus cultivation is increased.

Description

Technical field: [0001] The invention relates to the production field of Hericium erinaceus, in particular to a method for using a medium of Hericium erinaceus. Background technique: [0002] Hericium erinaceus is a famous and precious traditional Chinese dish, with tender meat, fragrant taste and delicious taste. It is one of the four famous dishes (hericium, bear's paw, sea cucumber, shark's fin). It is known as "mountain delicacy Hericium erinaceus and seafood bird's nest"; Hericium erinaceus has high nutritional content, with 26.3 grams of protein per 100 grams, which is twice that of shiitake mushrooms. It contains up to 17 kinds of amino acids, of which 8 are needed by the human body. Every 100 grams of hericium contains 4.2 grams of fat, which is a veritable high-protein, low-fat food, and is also rich in various vitamins and inorganic salts. Hericium erinaceus has the effects of increasing appetite, enhancing the barrier function of gastric mucosa, increasing th...

Problems solved by technology

[0003] At present, the medium for Hericium erinaceus on the market uses 26% wood chips, 20% wheat husks, 2% gypsum or calcium carbonate, 1% sugar, and 1% superphosphate as the main raw materials to cultivate Hericium erinaceus, and the carbon source nutrition of miscellaneous wood chips The elements are single, and the growth environment of the cultivated Hericium erinaceus has many limiting factors, and the yield is relatively low, and the wheat husk is selected as the nitrogen source for the growth of Hericium erinaceus, and its nitrogen element is difficult to be decomposed and absorbed by the root system of Hericium erinaceus, which is not conducive to The expansion of Hericium erinaceus strains and caps has resulted in less nutritional value and ingredients of Hericium erinaceus, and lower content of trace elements, which is not conducive to people's normal nutritional intake
