Hericium erinaceus medium and its preparation method

Abstract

The invention discloses a practical Hericium erinaceus medium. The formula of the medium comprises the following ingredients: by weight, 30-35% of saw dust of broad leaf, 20-25% of dry cow dung, 0.15-0.25% of vitamin B1, 3-5% of fructose, 2-4% of urea, 6-8% of gravel stone, 3-5% of calcium superphosphate and 1-3% of gypsum. By the adoption of the preparation method, the medium thalli grows vigorously, contents of protein and vitamin C in the medium are high, nutritive value of the thalli is high, utilization efficiency of the strain for the medium is high, biotransformation rate is high, costs are saved, and economic benefit of Hericium erinaceus cultivation is raised.

Description

technical field [0001] The invention relates to the production field of Hericium erinaceus, in particular to a culture medium of Hericium erinaceus and a configuration method thereof. 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).

Problems solved by technology

[0003] At present, Hericium erinaceus medium on the market uses 26% sawdust, 20% wheat skin, 2% gypsum or calcium carbonate, 1% sugar, 1 superphosphate % is used as the main raw material to cultivate Hericium erinaceus, the carbon source and nutrient elements of miscellaneous wood chips are single, the growth environment of the cultivated Hericium erinaceus is more restrictive, and the yield is relatively low, and wheat husks are selected as the nitrogen source for the growth of Hericium erinaceus. Nitrogen is difficult to be decomposed and absorbed by the root system of Hericium erinaceus, which is not conducive to the expansion of tea tree mushroom strains and caps, resulting in the growth of tea tree mushrooms with less nutritional value and components, and lower protein content, which is not conducive to people's normal nutrition. intake
