Speaking of Cordyceps sinensis, everyone agrees that it is deified overnight, and everyone is amazed at its magic. However, in recent years, from the major information platforms, we often see that there are no insects to dig in the army of collecting cordyceps sinensis and the wild resources are on the verge of extinction. Not only do people lament that there are fewer and fewer good things, but they will disappear before they have time to try. In order to make this high-end edible fungus become a dish that ordinary consumers can afford, edible fungus experts have made various attempts and developed many similar products, but they are all called Cordyceps. Some use bat moth larvae as parasites, and some use silkworm as parasites, but the nutritional value is roughly the same. Today, Nong Zhijun will take you to see how to use the silkworm eggs Cordyceps sinensis.
How did a lovely silkworm baby evolve into a complex of edible fungi and insects? To put it bluntly, it is planted. Next, let's take a look at how to grow Cordyceps in five steps.
Mushroom production and sericulture
To put it bluntly, making bacteria and raising silkworms are the preparation stages of raw materials. As long as they are both, it is logical to plant the favorite Cordyceps sinensis. For silkworm and cordyceps, because the silkworm can be cultivated all year round under the current technical conditions, there is no choice of seasons. If you plan to use the original ecological mulberry leaves for breeding, you should pay attention to the harvest season of the mulberry leaves.
Bacterium-making: It is well known that the fungus of Cordyceps sinensis belongs to Cladosporium, so we should use Cordyceps strains with clear source, strong parasitism to silkworm larvae, strong disease resistance and stress resistance, high quality and high yield when selecting bacteria.
Prepare liquid strains. First of all, we need to know the formula of liquid strain. The main components are glucose 1%, peptone 3%, potassium dihydrogen phosphate 0.3%, magnesium sulfate 0.3%, and the pH is adjusted to 5.6. Then the prepared liquid culture medium was autoclaved at 12℃ and 0. 12 MPa for 30 minutes. After cooling, the mycelium on the surface of the test-tube seed culture medium was scraped off with an inoculation shovel and inoculated into the liquid culture medium. After inoculation, it was transferred to a culture room and treated in the dark at 22℃.
Through our introduction, I believe everyone has a deeper understanding of the breeding methods of Cordyceps sinensis.
