Abstract

The invention belongs to the technical field of artificial cultivation of edible mushrooms, and particularly relates to an artificial cultivation method for increasing the content of polysaccharide in cordyceps sobolifera sporocarp. According to the cultivation method for increasing the content of the cordyceps sobolifera polysaccharide in the cordyceps sobolifera sporocarp, on the basis of a conventional cordyceps sobolifera sporocarp cultivation process, dead leaves and pruned spindling leaves generated in succulent plants bred by themselves are added into a solid culture medium of cordyceps sobolifera, it is surprisingly found that in the solid fermentation process of cordyceps sobolifera, the dead leaves and leaves of the added succulent plants can effectively induce accumulation of the cordyceps sobolifera polysaccharide, and the content of the cordyceps sobolifera polysaccharide in the cordyceps sobolifera sporocarp is increased.

Description

technical field [0001] The invention belongs to the technical field of artificial cultivation of edible fungi, and in particular relates to an artificial cultivation method for increasing the polysaccharide content of Cordyceps cicadae in fruiting bodies. Background technique [0002] Cicada is one of the traditional precious Chinese medicinal materials in my country, also known as cicada and Cordyceps cicadae. The existing research results show that cicadae is similar to the amino acids in the main components of many kinds of Cordyceps, and has different degrees of tonic effect. The biologically active substances contained in Cordyceps cicadae that have been reported so far include nucleosides, proteins, sugars, alkaloids, sterols, etc., and polysaccharides are one of the important ones. Studies have found that Cordyceps polysaccharides have pharmacological effects such as anti-tumor, immune suppression, immune enhancement, anti-oxidation, anti-aging, liver protection, and...
