Culture medium for wild-taste pleurotus eryngii and preparation method of culture medium

Abstract

The invention relates to a culture medium for wild-taste pleurotus eryngii and a preparation method of the culture medium. The culture medium comprises the following components in percentages: 57.5% of peanut vines, 22.5% of cottonseed hulls, 17.5% of potatoes, 0.25% of sucrose, 0.15% of quicklime, 0.3% of slaked lime, 0.25% of calcium superphosphate, and 0.225% of magnesium sulfate. According tothe method disclosed by the invention, in the preparation process, the ground potatoes are immersed into hot water with a water temperature of higher than 50 DEG C, quick stirring is performed, the amount of hot water can be ensured that a potato liquid is in a dilute and thin paste state after the potatoes are fully dissolved and expanded and cooled to normal temperature, the cottonseed hulls harvested in a current year are put into a retting pond, a certain amount of water is added, the retting pond is kept relatively sealed, the environmental temperature in the retting pond is 32 DEG C or more, retting is performed, the potatoes and the cottonseed hulls are mixed with the fermented peanut vines, so that nutrient ingredients are decomposed and easier to absorb; the sucrose, the quicklime, the slaked lime, the calcium superphosphate and the magnesium sulfate are sprayed on the surface of the culture medium, so that absorption and growth of the pleurotus eryngii are facilitated; and the peanut vines facilitate improving the wild taste of the pleurotus eryngii.

Description

technical field [0001] The invention relates to a wild-flavored pleurotus eryngii culture medium and a preparation method, which is a culture medium capable of cultivating high-protein, fine-grained pleurotus eryngii mushrooms. The preparation method is simple, and the nutrient component retention is high, belonging to the field of edible strain cultivation. Background technique [0002] Pleurotus eryngii, also known as Pleurotus eryngii, is a large fleshy toadstool belonging to the class Basidiomycetes, Agaricaceae, Pleurotaceae, and the genus Pleurotus. Pleurotus eryngii is rich in nutrition, rich in protein, carbohydrates, vitamins and minerals such as calcium, magnesium, copper, zinc, etc. The protein contains 18 kinds of amino acids, of which 8 kinds of amino acids necessary for the human body are complete, which can improve the immune function of the human body. It has the effects of anti-cancer, lowering blood fat, moisturizing the stomach and beautifying, and is an e...

Problems solved by technology

The traditional Pleurotus eryngii culture medium uses a large amount of rotten crop straw to scatter the strains of Pleurotus eryngii on it. The growth of the strains is uneven and it is not easy to pick uniformly. The lack of some nutrients in Pleurotus eryngii affects the growth head, prolong the growth cycle, reduce the yield
