Method for preparing zinc-rich hericium erinaceus medium

Abstract

The invention discloses a method for preparing a zinc-rich hericium erinaceus medium. The method comprises the following steps of (1) picking, disinfecting and drying wheat bran and medical stone particles; (2) preparing zinc-rich soil with 5-10% zinc in percentage of weight and mixing the zinc-rich soil with the wheat bran and medical stone particles which are obtained in the step (1) to obtain major ingredients; (3) drying and mixing hardwood sawdust and dried cow dung and crushing the mixture to particles with the diameter of 1 to 2 mm so as to obtain minor ingredients; (4) mixing pectin, urea, diatomaceous earth, odium selenite, ammonium molybdate, ferric sulfate and calcium dihydrogen phosphate to obtain a solution and mixing the solution with particles which are obtained in the step (3) to obtain minor ingredients; and (5) mixing the major ingredients and the minor ingredients. The zinc-rich soil is a compound of zinc-rich powder and soil. By the zinc-rich hericium erinaceus medium, thalli grow vigorously, the zinc content of Hericium erinaceus is high, nutritious value of the thalli is high, utilization efficiency of strain for the medium is high, biological efficiency is high, the cost is saved, and the economic benefit of the hericium erinaceus is improved.

Description

[0001] Technical field: [0002] The invention relates to the production field of Hericium erinaceus, in particular to a method for manufacturing Hericium erinaceus culture medium. [0003] Background technique: [0004] 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 has the title of "mountain delicacy Hericium erinaceus and seafood bird's nest"; Hericium erinaceus has a high nutritional content, containing 26.3 grams of protein per hectogram, 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 ...

Problems solved by technology

[0005] At present, the culture medium of Hericium erinaceus on the market is 26% of sawdust, 20% of wheat skin, 2% of diatomaceous earth or calcium carbonate, 1% of sugar, and 1% of superphosphate as the main raw materials to cultivate Hericium erinaceus and the carbon of miscellaneous sawdust. The source of nutrient elements is single, the growth environment of the cultivated Hericium erinaceus has many limiting factors, and the yield is relatively low, and wheat husk is selected as the nitrogen source for the growth of Hericium erinaceus, and its nitrogen is difficult to be decomposed and absorbed by the roots of Hericium erinaceus. It is not conducive to the expansion of Hericium erinaceus strains and caps, resulting in less nutritional value and components of Hericium erinaceus grown, and a lower content of trace elements, which is not conducive to people's normal nutritional intake
