Oyster Mushroom Cultivation Techniques（1）

The short-term sterilization technology of fermented materials first ferments the culture materials. The biological heat generated by biological fermentation will kill most of the bacteria in the culture materials, and then the remaining bacteria and insect eggs will be eliminated through a short period of high temperature treatment. It has the advantages of saving labor and fuel, reduces production costs, and is easily accepted by mushroom farmers. After years of trial and demonstration, this technology has basically formed a mature technical system and has good application value.

Under the conditions of pure cotton seed hull culture material, the biological transformation rate reaches 130% to 150%, which is basically the same as clinker cultivation; the yield of bacterial rods reaches more than 98%.

If corn cobs are added to the culture medium, it is best to soak the corn cobs in water for 1 to 2 days in advance. Select a plot of appropriate size, shovel the soil and compact it, lay a layer of about 10cm with cottonseed hulls, then lay about 10cm of corn cobs, and spread them crosswise and repeatedly until the pile height is 80 ~ 100cm. When laying the main ingredients, add bran, lime, gypsum, and coarse salt in layers, and add water while spreading. The moisture content is about 70% for fermentation. Add a ventilation hole with a diameter of 8cm every 40cm on the material pile to increase oxygen and promote fermentation. If the weather is cool, cover with plastic film 1 to 3 days before fermentation to increase the temperature and promote fermentation. Remove the film when the temperature in the pile reaches 50 ~ 60℃. After 4 to 5 days, turn the pile once when the temperature inside the pile reaches 70 to 75℃. At this time, the pile is covered with white and dense actinomycetes. Turn the pile again after 2 to 3 days, turn the pile 2 to 3 times, and bag it after 7 to 10 days. Use normal pressure and high temperature sterilization. When the temperature of the culture material in the bag reaches 100℃, keep it for 3 to 4 hours. Other management measures are the same as traditional cultivation methods.
