Application of Lime in Edible Fungi production
Lime has a significant disinfection and germicidal effect, but also rich in calcium, which is widely used in the production of edible fungi.
1. The application on the site removes weeds around the site, sprinkles a layer of lime powder, then cleans up the culture room, sprays conventional insecticides, and sprinkles a layer of lime powder. This can kill some miscellaneous bacteria, reduce the pollution base, especially bacterial pollution, and prevent pests such as slugs from invading the site.
two。 Application in culture materials most edible fungi can grow normally in slightly alkaline culture materials, with the exception of acid-loving edible fungi such as hericium Erinaceus. Adding 1% or 2% lime to the culture material 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 materials, compared with adding 2% lime and not adding lime, the contamination rate of miscellaneous bacteria in the former is less than 2%, and the latter is as high as 20% and 30%. Because the acidity of the material without lime is too high after composting and fermentation, and the pH value is generally below 5: 6, which is suitable for the growth of all kinds of miscellaneous bacteria and is easy to cause explosive pollution of miscellaneous bacteria. However, the culture material added with lime is alkaline, and the pH value can be maintained about 8 after fermentation, so it is difficult for miscellaneous bacteria 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.
3. In the application of rodent control and pest control, because the mycelium has a special smell, mice like to bite very much. if lime is used on the basis of drug anti-rodent, it can get twice the result with half the effort. A layer of lime powder can be spread at the entrance and exit of the bacteria room, and the mice will stop for fear of inhaling lime.

Key technical points of "mushroom bursting" of edible fungi
The so-called "mushroom explosion" means that when edible fungi are cultivated, through artificial regulation, the after-ripening time of the mushroom bag is prolonged (more than 10 days), the maximum amount of biological energy is accumulated, and the mushroom forms the "explosion" trend. The conventional cultivation lasts for 3~5 months, the biological efficiency is 100%, and the 3~4 tide mushroom is "mushroom explosion". The overall yield is complete at one time, and the highest biological efficiency can reach 160%. The production effect not only shortens the cultivation management time, It can also improve the quality and commodity value of mushroom products, which is the same as a batch of conventional cultivation.

Ten fresh-keeping methods of Edible Fungi
The fresh mushrooms harvested in the cold storage are arranged and put into baskets and baskets and covered with multi-layer wet gauze or hemp bags. Put the cylinder in the shade, there is a small amount of water in the cylinder, put the wooden frame on the water, put the basket and basket on the wooden frame, and then seal the cylinder mouth with thin film. 2. After dormant and fresh-keeping, put it in the room above 25 ℃ for 3-5 hours to make it breathe vigorously, and then put it in the cold storage of about 0 ℃ for about 12 hours, and the shelf life of about 20 ℃ is about 4-5 days. The method of controlled atmosphere preservation is to control the temperature of the environment manually.
