The invention relates to an
Oudemansiella raphanipes liquid strain culture medium and a preparation method thereof. The liquid strain culture medium is prepared by using corn distiller's grain liquor as a major component and adding a small volume of
red soil extract to the corn distiller's grain liquor. The corn distiller's grain liquor contains 90% to 96% of water, the rest 4% to 10% of dry matters are rich in
carbon source,
nitrogen source, vitamins and the like which are essential to the growth and development of edible fungi, and the
red soil extract is rich in mineral substances and micro-elements, so that nutrients which are essential to the growth of
Oudemansiella raphanipes liquid strains can be provided. According to the
Oudemansiella raphanipes liquid strain culture medium, the amount of components of the formula is small, the raw materials are common and are readily available, and the cost is low. The preparation method of the culture medium is simple in operation, so that popularization and application are easy. Through culturing the Oudemansiella raphanipes liquid strains by using the culture medium, the
pollution caused by the corn distiller's grain liquor is avoided, the cost is greatly reduced, meanwhile, Oudemansiella raphanipes mycelia are robust in growth, high in kink force, pure white in color and high in
growth speed, the
mushroom emergence is easy, the quality is good, and the efficiency is high, so that problems in strain supply during the large-scale cultivation and industrialized development of Oudemansiella raphanipes are solved, a scientific and technological basis is laid for the sustainable utilization of precious
wild mushroom resources, and the economic and
social benefits are remarkable.
