Culture medium of pleurotus eryngii and preparation thereof

From the paper

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.
