Method for preparing cordyceps militaris and toadstool fusion strain

The invention discloses a method for preparing a cordyceps militaris and toadstool fusion strain. The method includes: performing fusion screening on cordyceps militaris and toadstool to obtain the fusion strain, wherein screening refers to screening fusion strains having following features that compared with cordyceps militaris and toadstool, biomass of the fusion strains is increased, product type and product yield of the fusion strains are also increased, and the product type is embodied in monosaccharide type forming polysaccharide, adenosine and cordycepin. By utilizing the method to prepare the fusion strain, fusion breeding study of cordyceps militaris strains and toadstool strains can be conducted, active ingredients of rare medicinal and edible fungi are enriched, and one fungus with multiple effects and effective supplementing of bioactive substances of cordyceps militaris resources and toadstool resources are realized, so that the objectives that advantages of physiologically active ingredients are
