Method for field culture of cordyceps sinensis and vegetation recovery in alpine-cold cordyceps growing areas

Abstract

The invention relates to a method for field culture of cordyceps sinensis and vegetation recovery in alpine-cold cordyceps growing areas. Cordyceps sinensis is an insect herb which is formed by hepialus larvae (host) after being infected by fungus cordyceps sinensis and is a special product of a biological chain of fungus, insects and plant in a special habitat. The invention belongs to Field Culture of Wild Medicine biological engineering and has the advantages of proliferating fungus and the hosts in alpine-cold road and field growing areas, increasing and protecting alpine meadow and alpineshrub and meadow vegetation, compensating the activity of the biological chain, developing geographical (biological) resources of cordyceps sinensis habitat which is difficult to simulate by human, decreasing natural enemy hazard to protect the rare species of cordyceps sinensis with stable production and good quality, and protecting and improving the fragile alpine meadow vegetation. The methodadopts different species of hosts for egg-increasing assistance by levels and regions to increase the hatching rate and the larva density; the fungus is separated and purified, and the fungus source is provided through ferment, so that the infection rate of insects by fungus is improved; meanwhile, the favorite plant of host larva is compensated, and growth regulator and special fertilizer are applied to protect the alpine meadow vegetation.

Description

technical field [0001] The invention belongs to the bioengineering of "Wild Medicine Field Cultivation", in particular to a method for field cultivation and vegetation restoration of Cordyceps sinensis in alpine Cordyceps production areas. Background technique [0002] Cordyceps sinensis (Cordyceps sinensis) is a combination of insects and fungi formed after the larvae of the Cordyceps sinensis (berk) sacc are parasitized by the larvae of the Cordyceps sinensis (berk) sacc in the alpine region. It is a special product of the biological chain of fungi, insects, and plants in a unique habitat , has always been born and derived. The host bat moth spends 98% of its life in the soil, and the host larvae eat the underground parts of alpine meadows and alpine shrub meadows. Vegetation is destroyed due to encroachment, coupled with man-made predatory excavation and natural enemies, Cordyceps resources are becoming increasingly scarce. Cordyceps sinensis is a unique rare and precio...

Problems solved by technology

In order to meet the market demand, Cordyceps fungus is used to industrialize and expand fermentation in China, or Cordyceps fungus is inoculated on silkworm chrysalis and sprayed on mushroom bodies, etc. The products will not become the "worm shape" of Cordyceps sinensis, which will damage the attributes such as "rare" and suffer from the depreciation and objection of appearance. Approval of the combination of insects and bacteria; if the habitat of Cordyceps is simulated "wild medicine home planting", the investment is large. Many domestic and foreign experts have tried for many years, but failed to achieve their wish
