Spawn preparation method by switching enoki mushroom liquid spawn culture to solid spawn culture prior to liquification

Abstract

The invention discloses a spawn preparation method by switching enoki mushroom liquid spawn culture to solid spawn culture prior to liquification. The spawn preparation method includes the steps of liquid spawn culture, solid spawn culture, solid spawn liquification and the like, so that a tedious production mode of adopting a fermentation tank in liquid spawn culture is abandoned; paper pulp serving as a solid culture raw material is prepared into granules, and the characteristic that lignicolous fungi need lignin is kept, so that a certain clearance degree among mycelia in a culture vessel is achieved, and the requirement of a mycelium colonization process on oxygen is met.

Description

technical field [0001] The invention relates to a seed production method for converting liquid strains of Flammulina velutipes into solids and then liquefying them, and belongs to the technical field of Flammulina velutipes cultivation. Background technique [0002] At present, in edible fungus enterprises, the use of strains is mainly divided into solid strains and liquid strains. Among them, the liquid strain has many advantages such as short production cycle, consistent bacterial age, easy operation, and neat mushroom production. It is suitable for the factory standard production of Flammulina velutipes, but it also has the disadvantages of large equipment investment, high technical requirements, and many risks. . Although solid strains have many disadvantages, they have low cost, simple seed production process, and high strain stability, especially in strain purification, rejuvenation, fruiting test, strain preservation, and transportation. They also have irreplaceable ...
