Analysis on the wide use of Lime in the production of Edible Fungi

Lime has significant disinfection and germicidal effect, and is rich in calcium, so it is widely used in the production of edible fungi. Its application is summarized as follows:

I. Application on the site

Including strain culture room, mushroom, surrounding environment. First of all, remove the weeds around the site, sprinkle a layer of lime powder, and then clean the culture room, spray conventional insecticides, and then sprinkle a layer of lime powder, which can kill some miscellaneous bacteria and reduce the pollution base, especially bacterial pollution. at the same time, it can also prevent pests such as slugs from invading the site.

2. Application of culture materials

Most edible fungi can grow normally in slightly alkaline culture materials. In addition to acidophilia such as hericium Erinaceus, adding 1% 2% lime to the culture materials can basically control the pollution of miscellaneous bacteria in the cultivation of raw materials. Practice has proved that when Pleurotus ostreatus is cultivated with raw meal, the contamination rate of miscellaneous bacteria is less than 2% with 2% lime and 20% with 30% without lime, because the material without lime is acidic after fermentation, and the PH value is generally less than 5-6, which is suitable for the growth of all kinds of miscellaneous bacteria and is easy to cause explosive pollution of miscellaneous bacteria, while the culture material with lime is alkaline, and the PH value can be kept at about 8 after fermentation. Miscellaneous bacteria are difficult to grow, so as to achieve the purpose of controlling miscellaneous bacteria. In addition, because the lime contains a lot of calcium, the mycelium is strong and white after use. at the same time, it can also enhance the firmness of the fungus and increase the yield.

III. Application of rodent control and pest control

Because the mycelium has a special fragrance, mice like to eat it very much. if lime is used on the basis of drug prevention, it will get twice the result with half the effort. At the entrance and exit of the bacteria room, a row of lime powder, the mouse will stop because of inhaling lime. Fu Yuerong
