<p>Disclosed is a method for natural species rejuvenation of artificially bred strains, comprising the following steps: 1) infecting cordyceps host larvae with cordyceps strains artificially bred for more than 2 generations, screening the contaminated larvae which are firstly rejuvenated, and placing the larvae in a rejuvenation base after continuously culturing for 1 to 2 stages; 2) managing the transition periods so that the contaminated larvae adapt to the wild environment; 3) managing the specie nature exercise period of the bombyx insects; 4) rejuvenation of natural species of sexual spores and mycodermas; 5) collecting cordyceps with mature sexual spores, and transplanting to a sterilized culture medium to continuously culture after washing the insect-strain complexes; 6) after-ripening of the cordyceps; and 7) harvesting cordyceps strain materials. The method provides a strain guarantee for large-scale sustainable production of cordyceps.</p> |
