Culture medium of pleurotus eryngii and preparation thereof

Abstract

The invention discloses a Pleurotus eryngii culture medium and a manufacturing method thereof. The culture medium comprises 75 to 80 percent of cottonseed hulls or wheat straws or straws or corncob, 5 to 12 percent of wheat bran or rice husks, 8 to 10 percent of dry fowl manure, 3 to 8 percent of cornmeal, 1 to 2 percent of hemihydrate gypsum, 0.5 to 1.5 percent of sucrose and 0.5 to 1.5 percent of quicklime, and is added with 0.1 to 0.3 percent of potassium dihydrogen phosphate and 0.1 to 0.2 percent of magnesium sulfate according to the total amount of the compositions, and various compositions are calculated by weight percentage. The cottonseed hulls or the wheat straws or the straws or the corncob and the dry fowl manure are stacked and retted before use; and the culture medium after cultivation of Pleurotus eryngii is subjected to on-the-spot returning treatment. By adoption of the technical proposal, the method can make branched oyster mushrooms organisms well grown, overcome the defect that the prior art has no culture medium specially prepared for branched oyster mushrooms, simplify the production process, shorten the growth period of the Pleurotus eryngii, and improve the bioconversion of the Pleurotus eryngii.

Description

technical field [0001] The invention relates to a culture medium of pleurotus eryngii and a preparation method thereof. Background technique [0002] Pleurotus eryngii, formal name used at school: Pleurotus eryngii (DC.ex.Fr.) Quel, alias thorn celery side ear. Belonging to the Phylum Fungi, Basidiomycetes, Agaricaceae, Pleurotaceae, and Pleurotus. The flesh of Pleurotus eryngii mushroom is thick, crisp and tender, especially the stipe is dense, firm and milky white, and can be eaten entirely, and the stipe is more crispy and refreshing than the cap. ", is a new species of rare edible fungus that has been successfully developed and cultivated in recent years and integrates edible, medicinal, and dietotherapy. Mushroom body is rich in protein, carbohydrates, vitamins and minerals such as calcium, magnesium, copper, zinc, etc., which can improve the immune function of the human body. The role of vascular disease; the fruiting body of Pleurotus eryngii is rich in oligosaccha...

Problems solved by technology

But at present there is not a kind of culture medium specially used for the growth of Pleurotus chinensis. Generally, the culture medium of general-purpose fungi is used in the existing cultivation, so the pertinence is not strong, and the growth of Pleurotus chinensis cannot be satisfied effectively. The growth cycle is also longer, usually 130-140 days to mature

And to cultivate with clinker, the production cycle of clinker is long, the requirement of technical elements is higher, the production process is complicated, and the retting process will bring some harmful substances to the growth of Pleurotus eryngii, which inhibits the growth of Pleurotus eryngii and leads to its Reduced biotransformation
