Abstract

The invention belongs to the technical field of artificial cultivation of rare medical fungi and relates to a method for culturing cordyceps militaris by taking living tenebrio molitor larvae as hosts. According to the method, the living tenebrio molitor larvae are taken as the hosts, inoculation of cordyceps militaris liquid is performed by artificial injection, and the contaminated living tenebrio molitor larvae are ossified slowly along with growth of in-vivo hyphae to grow out cordyceps militaris fruiting bodies through culturing. By adoption of the method, the contamination rate of the tenebrio molitor larvae reaches 85% or above, the ossification rate reaches 80% or above, and the cordyceps militaris is rich in content of effective components including cordyceps polysaccharide, cordycepin and cordycepic acid. The method is simple in operating process, high in yield and low in cost, cultured products are rich in nutrition and high in medicinal value, and suitableness for large-scale cultivation and a promising application prospect are realized.

Description

Technical field [0001] The invention relates to a method for cultivating cordyceps militaris with live larvae of yellow mealworm as a host, and belongs to the technical field of artificial cultivation of rare medicinal fungi. Background technique [0002] With people’s understanding of the health functions of Cordyceps sinensis, demand has increased sharply, market resources are tight, and prices are high. Due to its limited output due to natural conditions, it is far from meeting the growing demand of domestic and foreign markets; at the same time, wild resources are infinite. Mining seriously damages the natural vegetation and ecological balance. Therefore, Cordyceps militaris, a substitute for Cordyceps sinensis, is developed to meet the needs of domestic and foreign markets and protect the ecological environment. [0003] Cordyceps militaris (Cordyceps militaris), also known as Cordyceps militaris, Cordyceps militaris, etc., has been tested by authoritative departments and cont...
