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 grasp of seven words: fresh, sparse, increase, dry, wind, dark, drop.
Fresh culture materials such as straw, corn stalk, wheat straw, etc. should be fresh and free of mildew, and be exposed to sunlight for 3 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, use lime to increase the pH value, so that the pH value of 8.5 - 9, or even higher, in order to create an environment of unfavorable acid rot growth and reproduction.
Dry and maintain the ventilation of Pleurotus ostreatus cultivation site for fresh air, which will facilitate 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.
To reduce the "double down": 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%, and second, reduce the mushroom cultivation site temperature. Trees can be planted around the site, or grow a long melon, and build a tall melon fence. In addition, if the temperature is too high (above 30°C), cool the gauze or spray mist in the ventilated area.
