Abstract

The invention discloses a silkworm pupa-worm grass culture method capable of improving yield and quality. The method is characterized by comprising the steps including preparation of liquid spawn, pupa sterilization, inoculation, cultivation in dark, wound treatment of pupas, cultivation in light, harvest and the like. Compared with the conventional culture method, the silkworm pupa-worm grass culture method disclosed by the invention is short in grass germination time, great in fruit body number, vigorous in growth and short in growth period, so that not only can the yield of the worm grass be increased, but also the growth period can be greatly shortened, and thus the economic benefits are greatly increased.

Description

technical field [0001] The invention relates to a method for improving the yield and quality of silkworm Cordyceps militaris. Background technique [0002] The traditional cultivation method of silkworm Cordyceps militaris takes a long time for cultivation, generally needs 60-80 days, and the number of spores is small, generally 3-5, and its yield and quality all need to be further improved. Contents of the invention [0003] The object of the present invention is to provide a method for cultivating Cordyceps militaris with simple method, short culturing time and high yield, which improves yield and quality. [0004] Technical solution of the present invention is: [0005] A method for cultivating silkworm Cordyceps militaris that improves yield and quality is characterized in that it comprises the following steps: [0006] ⑴Preparation of liquid strains: [0007] Preparation of liquid medium: Mix the following components by weight to prepare medium: 10-30 parts of gluc...
