Method for culturing cordyceps sinensis by taking unhulled wheat as culture medium

Abstract

The invention relates to a method for culturing cordyceps sinensis by taking unhulled wheat as a culture medium. The method comprises the following steps: preparing a culture medium by taking unhulled wheat grains as raw materials and cordyceps sinensis liquid strain as a strain, inoculating the wheat grain culture medium with the liquid strain, and culturing a cordyceps sinensis fruiting body. Applied wheat grain raw material sources are wide, and low in price; during the implementation, the inoculated cordyceps sinensis liquid strain use amount can be increased, and can penetrate into and be distributed into gaps among wheat grains due to no adhesion among the wheat grains, so that the medium is entirely contacted with the liquid strain, and hypha fully grows in the culture medium once the hypha germinates. In addition, steamed wheat grain hulls are cracked, wheat is exposed, the wheat is always wrapped by the hulls, so that the gelatinization and adhesion of the wheat can be effectively prevented and treated to influence the running and the growth of the hypha, the inoculated cordyceps sinensis strain can also directly contact with the wheatand absorb wheat nutrients; and the wheat is wrapped by the hulls, so that moisture is difficult to lose, and the sufficient moisture can guarantee the yield of the cordyceps sinensis.

Description

technical field [0001] The invention belongs to the technical field of biology, and in particular relates to a method for cultivating Cordyceps using unhulled wheat as a culture substrate. technical background [0002] Cordyceps, also known as northern Cordyceps sinensis, Cordyceps militaris, it is a complex of larvae and larvae of the fungus Cordycps sinensis (Berk.) Sacc parasitizing on the larvae of the larvae Mothidae. It is a traditional precious nourishing Chinese medicinal materials, together with natural ginseng and deer antler, are listed as the three major tonics. It has mild medicinal properties and can be eaten all year round. It is suitable for the old, young, sick, weak, and weak. It has wider medicinal value than other types of tonics. Since ancient times, people have used it as a tonic and medicinal product. [0003] Natural wild Cordyceps mainly grows in high-altitude and high-cold regions, and the composition of the growing environment is very harsh and c...

Problems solved by technology

However, rice and wheat tend to stick together after steaming, and the strains cannot penetrate into the material during inoculation, and the mycelia grow slowly after germination; in addition, rice and wheat tend to lose water, which in turn affects the yield of Cordyceps sinensis in the later stage
