Manual wild-imitation cultivation technology for pure strains of grifola

The invention relates to a manual wild-imitation cultivation technology for pure strains of grifola. The manual wild-imitation cultivation technology comprises the steps of land selection and land preparation, cultivation, seeding methods, management after seeding, management in a coming year, management in a third year, excavation and drying processing. In a biological angle, wild sclerotium tubers are polluted in the natural environment, and purity of the pure strains is achieved. Besides, the pure strain only have fungus age of half a year, wild grifola fungus tubers have the longest fungus age of five years, and the reproduction rate of the pure strains is one time more than that of the wild grifola fungus tubers.
