The excellent strain of volvariella volvacea was produced in forage medium for winter (10-15 ℃). After overwintering. Cultivation in advance proved to be of high quality and high yield. Then the maternal species (first-class species) were obtained by tissue separation method, and the culture continued to be expanded for production and use in the same year. When purchasing straw mushroom strains, mushroom farmers should pay attention to the following points: 1.
