Pleurotus ostreatus
In recent years, a serious new disease occurred in Pleurotus ostreatus production. Most of the disease occurred after the first harvest, and a few occurred after the second or third harvest. At the beginning of the disease, a small number of white dots grow on the surface of Pleurotus ostreatus culture material, which are tumor-shaped, very similar to the undifferentiated Pleurotus ostreatus fruit body primordium, gradually grow into a piece, and later become brown. The disease is highly infectious. Once it occurs, it no longer produces mushrooms normally. The cultivation personnel call this disease "white lump disease".

Cultivation medium plus plant ash Pleurotus ostreatus growth
When cultivating Pleurotus ostreatus with uncooked materials, adding proper amount of plant ash into the culture medium is beneficial to the growth of Pleurotus ostreatus. Because plant ash is alkaline, it has the function of disinfection and sterilization, which can inhibit the growth of various miscellaneous bacteria. At the same time, plant ash contains calcium, magnesium, iron, phosphorus and other trace elements, which can increase the nutritional components in the culture medium. In addition, plant ash has heat absorption and warming effect, which can create a good growth environment for mycelium growth. The method of adding plant ash to the culture medium is simple, just add 3%~4% of the plant ash to the culture medium after it has been soaked in water.
