Special culture medium for artificially cultivating pollution-free oyster mushrooms and preparation method of special culture medium

Abstract

The invention discloses a special culture medium for artificially cultivating pollution-free oyster mushrooms and a preparation method of the special culture medium. The culture medium is prepared from, by weight, 30-60 parts of corncobs, 15-20 parts of wood bits, 10-15 parts of bran, 4-5 parts of lime and 0.5 part of trace elements, wherein the ratio of materials to water is 1 to 1.5. The preparation method includes the following steps of firstly, keeping the temperature of the culture medium between 40 DEG C and 50 DEG C for 40-50 h; secondly, putting the culture medium in mushroom bags, and sterilizing the bags in a normal-pressure boiler at a temperature of 75 DEG C to 95 DEG C for 4 h; thirdly, cooling the mushroom bags to the normal temperature after sterilizing ends. The special culture medium is beneficial to edible mushrooms and not beneficial to growth of various types of moulds, various bacterial spores are cultivated into vegetative bodies, biological protein is synthesized, and fixed nutrients are improved; when the oyster mushrooms are artificially cultivated through the special culture medium, the pollution-free high-quality edible mushrooms can be obtained without using any pesticides in the oyster mushroom producing process, and the quality stability of the product is ensured.

Description

technical field [0001] The invention relates to a special culture medium for artificially cultivating pollution-free oyster mushrooms, in particular to a preparation method thereof, and belongs to the technical field of preparation of edible fungus products. Background technique [0002] Edible fungus Pleurotus (scientific name: Pleurotus otreatus; also known as Pleurotus otreatus; also known as Pleurotus otreatus, Oyster Mushroom, Black Peony Mushroom, Taiwan is also known as Xiuzhen Mushroom) is a species of Pleurotaceae under the order Agaricaceae under the Basidiomycota. It is a fairly common gray edible mushroom . The germ tubes of Pleurotus ostreatus continue to branch and elongate to form monokaryotic hyphae. Dikaryotic hyphae are formed after the combination of monokaryotic hyphae with different sexes (quality mating). Dikaryotic hyphae have lock-like unions on the septum. Dikaryotic hyphae rely on lock joints to continuously divide cells, produce branches, and gr...
