Pleurotus eryngii culture medium and preparation method

Abstract

The invention relates to a pleurotus eryngii culture medium and a preparation method. The pleurotus eryngii culture medium comprises soybean residue, wheat bran, rice bran, urea, quicklime, hydrated lime, glucose and potassium phosphate; the soybean residue is selected from residue which is obtained by soaking soybean and then squeezing soya-bean milk; the wheat bran is wheat skin which is obtained after wheat harvested in the current year is milled and is the wheat skin obtained from wheat of which the wheat flour yield is more than 75%, and the rice bran is obtained after rice harvested in the current year is milled. In the preparation process of the culture medium, the soybean residue, the wheat bran and the rice bran are mixed uniformly and spread smoothly, and then the urea, the quicklime, the hydrated lime, the glucose and the potassium phosphate are sprinkled on the surface of the culture medium. The preparation method is simple, the main nutrient elements are centralized in the surface of the culture medium, so that absorption and growth of pleurotus eryngii can be facilitated; the soybean residue, the wheat bran and the rice bran can supply rich nutrition for pleurotus eryngii for a long time.

Description

technical field [0001] The invention relates to a pleurotus eryngii medium and a preparation method, which is a medium for cultivating pleurotus eryngii with high nutritional value and good taste, and belongs to the field of medium. 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 high nutritional and health value. [0003] The nutrition of Pleurotus eryngii is selectively absorbed from t...

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 size, prolong the growth cycle, reduce the yield, and the current medium can only be used to cultivate Pleurotus eryngii once. After the production of Pleurotus eryngii, the medium should be cleaned up. Large, it is cumbersome to handle, and it takes a lot of material and manpower to clean the culture medium, and it takes a lot of material, manpower and financial resources to prepare the culture medium again
