Odosporium oudemansiella culture medium and preparation method thereof

The invention discloses an oudemansiella ovalis culture medium and a preparation method thereof, and belongs to the technical field of edible fungus cultivation. Comprising the following raw materials in percentage by mass: 26%-45% of reed residues, 12%-18% of pomace, 19%-26% of distillers' grains, 18%-26% of beanstalks, 0.1%-0.8% of urea, 1%-4% of gypsum powder and 0.9%-2.2% of a water-retaining agent. The raw materials of the prepared culture medium are the reed residues, the pomace and the vinasse, so that nutrients required by the growth of the oudemansiella homospora can be provided, and effective utilization of waste resources can be realized; the synthesized polyaspartic acid hydrogel is used as a water-retaining agent, so that the loss of water in a culture medium can be reduced to a great extent, and a certain antibacterial property can be provided. Therefore, the prepared culture medium is rich in nutrition and strong in water-retaining property, also has certain antibacterial performance, realizes
