Abstract:
Taking wild North Cordyceps as material,the key cultivation technology of North Cordyceps host was conducted.The results showed that the best bacteria age of liquid strains was 7~9 d,ozone solution was the best surface disinfection of pupa body,it was easy operation by inoculate on the lower edge of Silkworm pupa wing and bleeding less,with high rigid rate.Suitable conditions were determined by the orthogonal test,the results showed that the suitable temperature for the hyphae growth was 20~22℃,relative air humidity was 60%,the pupa rigid rate was the highest in no light condition.The suitable conditions for the sporocarp growth as follows,temperature for 20~22℃,relative air humidity for 60%~70%,light density for 250~500 lx,under this condition,the North Cordyceps growth was the best,the dry weight of North Cordyceps was the highest.
