Ecology-imitating soil covering cultivation method for cordyceps cicadae

Abstract

The invention discloses an ecology-imitating soil covering cultivation method for cordyceps cicadae. The aim is to realize real ecology-imitating cultivation to reduce exploitation of natural wild cordyceps cicadae and accordingly relieve the pressure caused by lack of cordyceps cicada wild resources. The method includes the steps that cordyceps cicadae strains (Dajiang mountain cordyceps cicadae)are inoculated into a triangular flask inclined plane and cultured for seven days at constant temperature, spores on the inclined plane are eluted with sterile water, the concentration of spore suspension liquid is adjusted, tussah pupae are injected with the spore suspension liquid, generally cultured at room temperature until white hyphae emerge and then covered with soil to be planted in a flower pot, the soil covering depths of the tussah pupae include the four depths of 1 cm, 2 cm, 3 cm and 4 cm for treatment, fifteen tussah pupae are involved in each treatment, and culturing is performed at the room temperature until sporocarps are mature; growth conditions are recorded for comparison, and finally it is obtained that the effects are good when the soil covering depths are 1 cm and 2cm.

Description

technical field [0001] The invention relates to the technical field of artificial cultivation of Cordyceps sinensis, in particular to the invention of an artificial cultivation method of cicadae with imitation ecology covered with soil. Background technique [0002] Cicada, also known as Cicada, Cicada, Hu Chan, etc., is the anamorphic Paecilomyces cicadae (Miquel) Samson of the ergot fungus Cordyceps cicadae X. Q.Shing, parasitic on Cicada (Cicada flammata Dist). Cicada is a traditional Chinese medicinal material in my country. Its sclerotium and the corpse (sclerotia) of the host insect can be used as medicinal parts. It has the effects of dispelling wind and heat, calming convulsions, and improving eyesight. Dispelling wind and relieving spasm, measles, conjunctival congestion, excessive tears. As an edible and medicinal fungus, cicadae has good nutritional value. It contains chemical components such as glycogen, mannitol, various alkaloids, proteins, various amino acids...

AI Technical Summary

Problems solved by technology

[0003] And due to the shortage of natural wild cicadae resources, people are more and more researched on the artificial cultivation of cicadae, but only the use of solid medium culture to obtain fruiting bodies or infect silkworm larvae or silkworm chrysalis through ordinary cultivation has been achieved at present. The obtained complex of insects and bacteria has not realized the real ecological imitation cultivation
