Shiitake mushroom substitute material containing yellow ginger residues and preparation method

Abstract

The invention provides a shiitake mushroom substitute material containing yellow ginger residues and a preparation method. The preparation method comprises the following steps of (1) bagging sterilization: uniformly mixing culture compost components according to the proportion as followed: 48 percent-64 percent of weed tree sawdust, 16 percent to 32 percent of yellow ginger residues, 19 percent of bran, and 1 percent of plaster; adding water to stir until the moisture of stirred cultivating materials can form water drops when being clenched by a hand, wherein the moisture content is 60 percent to 65 percent; using polyvinyl chloride fungus bags to package and seal; carrying out sterilization at the temperature of 125 DEG C for 2 hours or at ordinary pressure and the temperature of 100 DEG C for 12 hours; natural cooling to the room temperature; (2) inoculated culture: carrying out inoculated culture through prepared culture composts for culturing shiitake mushrooms in an inoculating room or on a super clean bench; putting the inoculated fungus bags onto a culture frame in a culture room; carrying out dark culture at the temperature of 24-26 DEG C; achieving a physiological ripening stage through a colouring stage after the bags are full of shiitake mushroom fungus filaments; (3) management of producing mushroom: when the fungus bags achieve the physiological ripening stage and the weather conditions are appropriate, putting the fungus bags in a mushroom producing shed to produce mushrooms, and picking the shiitake mushrooms when the shiitake mushrooms are grown to meet the commercial grade standard.

Description

technical field [0001] The invention relates to the cultivation technology of shiitake mushrooms, in particular to a shiitake mushroom substitute material containing turmeric dregs and a preparation method thereof. Background technique [0002] At present, the cultivation mode of shiitake mushrooms in my country mainly adopts the substitute material cultivation mode. The substitute shiitake mushrooms are cultivated with raw materials such as wood chips, bran, and gypsum. Among them, wood chips are the main raw materials, generally accounting for about 80% of the formula. In recent years, with the continuous expansion of my country's shiitake mushroom industry, the demand for wood is also increasing, which to a certain extent has caused the contradiction between the raw materials required for shiitake mushroom production and the protection of natural forests. [0003] At present, the breakthroughs made in formula changes mostly use corncobs, cottonseed hulls, crop straws, etc...

Problems solved by technology

At present, the annual demand for saponin in the world has exceeded 6,000 tons, and the annual gap of saponin in China alone has reached more than 3,500 tons. The saponin component in turmeric only accounts for about 0.8% of its mass, resulting in A large amount of turmeric slag has caused great pollution to the local environment

[0005] Utilize turmeric slag to cultivate edible fungus to have only a small amount of reports at present, and Ankang Agricultural Science Institute of Shaanxi Province utilizes turmeric slag to cultivate Pleurotus ostreatus, Pleurotus eryngii, and Pleurotus eryngii to succeed; Edible and Medicinal Mushrooms and Feed Methods” mentioned the method of using turmeric dregs to produce edible and medicinal fungi, but the formula for protection of this method is very limited, and the formula for protection of this patent application cannot be used to produce wood rot that needs to be cultivated with wood, such as shiitake mushrooms. bacteria
