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

Embodiment 1

[0027] Take 20kg of potatoes, grind them into granules or powders, and the diameter of the particles is not more than 10mm. Soak the ground potatoes in hot water with a temperature higher than 50°C and stir them evenly. The amount of hot water should ensure that the potatoes can fully absorb water and swell. Under the action of stirring, a thin paste is finally formed, and cooled naturally until it reaches room temperature; take 10kg of corn flour, add it to cold water, soak for 7 hours, and the corn flour will fully absorb and swell; mix the potatoes and corn flour that have swelled after absorbing water Put together and stir evenly, add 55kg of distiller's grains, add water and stir until the overall moisture content of the medium is 60%, after stirring evenly, spread it out flat to form a 1.5cm thick medium; take 0.5kg of sucrose and 2kg of peptone , 0.1kg of quicklime, 0.2kg of slaked lime, 0.1kg of potassium dihydrogen phosphate, and 0.1kg of magnesium sulfate are dissolve...

Embodiment 2

[0030] Take 22kg of potatoes, grind them into granules or powders, and the diameter of the particles is not more than 10mm. Soak the ground potatoes in hot water with a temperature higher than 50°C and stir them evenly. The amount of hot water should ensure that the potatoes can fully absorb water and swell. Under the action of stirring, a thin paste is finally formed, and cooled naturally until it reaches room temperature; take 12kg of corn flour, add it to cold water, soak for 7 hours, and the corn flour will fully absorb and swell; mix the potatoes and corn flour that have swelled after absorbing water Put together and stir evenly, add 57kg of distiller's grains, add water and stir until the overall moisture content of the medium is 65%, after stirring evenly, spread it out flatly to form a 1.7cm thick medium; take 0.7kg of sucrose, 2.2 of peptone kg, 0.15kg of quicklime, 0.22kg of slaked lime, 0.15kg of potassium dihydrogen phosphate, and 0.15kg of magnesium sulfate are dis...

Embodiment 3

[0033]Take 23kg of potatoes, grind them into granules or powders, and the diameter of the particles is not more than 10mm. Soak the ground potatoes in hot water with a temperature higher than 50°C and stir them evenly. The amount of hot water should ensure that the potatoes can fully absorb water and swell. Under the action of stirring, a thin paste is finally formed, and cooled naturally until it reaches room temperature; take 13kg of corn flour, add it to cold water, soak for 7 hours, and the corn flour will fully absorb and swell; mix the potatoes and corn flour that have swelled after absorbing water Put together and stir evenly, add 58kg of distiller's grains, add water and stir until the overall moisture content of the culture medium is 67%, after stirring evenly, spread out flatly to form a 1.8cm thick culture medium; take 0.8kg of sucrose, 2.3 of peptone kg, quicklime 0.16kg, slaked lime 0.23kg, potassium dihydrogen phosphate 0.16kg, magnesium sulfate 0.16kg, dissolved ...

Abstract

The invention relates to a high-protein pleurotus eryngii culture medium and a preparation method. The distribution ratio of the culture medium is: 58% of distiller's grains, 22% of potatoes, 12.5% ofcorn flour, 0.8% of sucrose, 2.5% of peptone, 0.15% of quicklime, 0.22% of slaked lime, 0.15% of potassium dihydrogen phosphate and 0.15% of magnesium sulfate. In the preparation process, the potatoes and the corn flour are respectively placed in hot water and cold water to fully absorb water and expand, then mixed with the distiller's grains, so that the nutrient components in the potatoes and the corn flour are more easily absorbed, the sucrose, the peptone, the quicklime, the slaked lime and the potassium dihydrogen phosphate, the magnesium sulfate are sprayed on the surface of the culturemedium which is beneficial to the absorption and growth of the pleurotus eryngii, and the distiller's grains are beneficial to the improvement of the protein content of the pleurotus eryngii.

Description

technical field [0001] The invention relates to a high-protein pleurotus eryngii culture medium and a preparation method, which is a culture medium capable of cultivating high-protein, fine-grained pleurotus eryngii, has a simple preparation method, and has high nutrient component 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...
