Method for increasing yield of natural cordyceps sinensis

Abstract

The invention provides a method for increasing the yield of natural cordyceps sinensis. The method comprises the following steps of (1) selecting a base for increasing the yield of natural cordyceps sinensis; (2) placing a trapping lamp; (3) preparing trapping liquid; (4) screening and preparing culture medium of hepialidae hirsutella sinensis and paecilomyces hepialid; and (5) controlling yield increase conditions. According to the method, at the adult stage, a high pressure mercury vapor lamp is used for trapping, so the imagoes of hepialus armoricanus around the lamp fly to the base, and the egg-laying amount is increased; ethanol, vinegar and sugar solution are sprayed on meadows beneficial to larva growth, so the larvae gather together; and the hepialidae hirsutella sinensis and the liquefied paecilomyces hepialid are sprayed on the gathering area of larvae to raise the infection rate of the larvae of hepialus armoricanus, so the aim of increasing the yield of cordyceps sinensis is achieved and the industrialized production is realized.

Description

technical field [0001] The invention relates to a production increasing method of natural Cordyceps sinensis. Background technique [0002] Cordyceps ( Cordyceps sinensis (Berk.) Sacc) grows in Qinghai, Gansu, Tibet, Sichuan, Yunnan, Guizhou and other places in alpine regions and snow-capped meadows. After gestation in autumn, winter, spring and summer, the compound fruiting body of the larvae of the bat moth and the Cordyceps fungus is produced. It is a rare and valuable food and medicine dual-purpose tonic and enjoys a high reputation. "Materia Medica Congxin" records: Cordyceps has the functions of "protecting the lungs and kidneys, stopping bleeding and resolving phlegm, and relieving labor cough". "Compendium of Materia Medica Supplements" records that it has the effect of "secret essence and Qi, specially nourishing the gate of life", and "cooking with ducks can resist ginseng". "Chongqing Tang Essay" records that Cordyceps sinensis "has the properties of warming an...

Problems solved by technology

[0004] Generally speaking, there are not many reports on the success of artificial production increase of Cordyceps sinensis in China, and most of them still belong to the category of bionic cultivation, that is, the form of "using the phototaxis and chemotaxis of bat armyworms to induce adult insects to increase production", which is affected by climate, ecology, and environment. Conditions such as poor repeatability have not been verified in production and practice, and normal artificial cultivation has not actually been carried out in China.

Some experts believe that the artificial cultivation of Cordyceps sinensis is still difficult at present, and affected by the differences in natural conditions in various places, even successful examples are still far from industrialized production, and the mycelium is basically obtained by submerged fermentation.
