In summer, the weather is hot, rainy and humid, and it is easy to breed rancid bacteria. If you do not pay attention, it will cause loss to the oyster mushroom production. How to prevent acid rot of Pleurotus ostreatus cultivation material, according to many years of practice, the author believes that the main focus on six words: fresh, sparse, increase, wind, dark, drop. Fresh culture materials such as straw, corn stalk, wheat straw, etc. should be fresh and mildew-free. They should be exposed to the sun for three days before use. Loosely use small plastic bags with a diameter of 20 cm or less to grow Pleurotus ostreatus. Only 1 layer should be stacked during germination. Do not overlap to facilitate heat dissipation. Increase in the deployment of culture materials, the use of lime to increase the pH value, so that the pH value of 8.50-9, or even higher, to create an environment of unfavorable acid rot growth and reproduction. The wind maintains the ventilation of Pleurotus ostreatus cultivation field for fresh air, which is conducive to the growth of Pleurotus ostreatus. The dark green mushroom's mycelial growth environment is dark, and black cloth and straw curtains can be used to block the doors and windows, but there must be some scattered light when the buds form. The implementation of "double drop": First, to reduce the humidity of culture materials, the general winter and spring culture materials adjusted to 60% -65% humidity, and summer should be reduced to 50% -55%. The second is to reduce the temperature of the oyster mushroom cultivation site. Trees can be planted around the site, or long vines can be planted to form a tall melon vine fence. In addition, if the temperature is too high (above 30°C), cool the gauze or water mist in the ventilated area. Source: "Agricultural Science and Technology and Information"
