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

Abstract

The invention relates to a high-quality pleurotus eryngii culture medium and a preparation method. The culture medium comprises the components in percentage by weight as follows: 58% of grain stillage, 22% of bean cakes, 12.5% of corncobs, 0.8% of glucose, 2.5% of urea, 0.15% of quick lime, 0.22% of hydrated lime, 0.15% of potassium dihydrogen phosphate and 0.15% of magnesium sulfate. In a preparation process, the bean cakes are smashed, and granular bean cake granules are obtained; the bean cake granules are soaked in hot water with a temperature higher than 60 DEG C, the water temperature is kept to be constant, soaking is performed for more than half an hour, the mixture is cooled naturally, and a bean cake soaking solution is obtained; the corncobs are placed into a sealed transparent glass or plastic container, water is added to the container, and the height of the water level is in accordance with the stacking height of the corncobs; the container is sealed and placed in a natural environment where sunlight can directly eradiate, and retting is performed for three months; and the mixture is mixed with the grain stillage, the culture medium is paved, the glucose, the urea, the quick lime, the hydrated lime, the potassium dihydrogen phosphate and the magnesium sulfate are prepared into a nutrient solution, and the surface of the culture medium is sprayed with the nutrient solution. The absorption and growth of pleurotus eryngii are facilitated, and the protein quality of the pleurotus eryngii is improved by the aid of the grain stillage.

Description

technical field [0001] The invention relates to a high-quality pleurotus eryngii culture medium and a preparation method, which is a culture medium capable of cultivating high-protein, fine-grained pleurotus eryngii mushrooms, has a simple preparation method and high nutrient retention, and belongs to the field of cultivating edible strains. 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 edible fungus with...
