Who knows how to manage black fungus during the rainy season?

Weiping Town Farmer Consultation: There is too much rain this season. How to scientifically manage black fungus? Song Jiling, Special Rapporteur of Science and Technology: In recent months, Chun'an area has mostly suffered from continuous heavy rainfall and high air humidity. , has a certain impact on the production of black fungus. In order to ensure the high quality and stable production of black fungus, the following management methods can be used to provide a good growth environment for black fungus: 1. Dig ditches and drain water in time. Long-term soaking of bacteria beds and rods by rainwater will greatly affect the normal growth of black fungus and cause severe yield reduction. Drainage ditches lower than the bacteria beds can be dug around the bacteria beds to facilitate ventilation of the bacteria beds and mycelial growth. 2. Cover the shed to prevent rainwater. The membrane of the arch shed is only covered at the top, and the surrounding area should be conducive to ventilation. Avoid direct impact of rainwater on the border surface or bacteria sticks, and prevent long-term dripping of water from causing the bacteria sticks to rot and deteriorate, affecting the quality of the ears and ear pieces. 3. Prevent and control diseases and pests, and use medicines in a timely manner. In long-term high-humidity weather, some diseases and insect pests that prefer dampness will occur. Although the pH of the cultivation material is not suitable for the growth of pests and diseases under normal conditions, it can easily cause the occurrence of mold in a high-humidity environment. Once mold occurs, it must be controlled promptly to prevent its spread. You can rinse with concentrated lime water to inhibit miscellaneous bacteria, or use 75% alcohol to disinfect, or use a small amount of green mold net for local treatment and disinfection. If nematodes, slugs, etc. are found, you can sprinkle some lime powder around the bacterial bed in advance to reduce the occurrence of pests or inhibit the crawling movement of pests. You can also capture them manually or kill them with drops of 50% edible salt water or 5% alkaline water. Try not to use them. Or use less chemical pesticides to reduce pollution to edible fungi and the environment. 4. Harvest at the right time.
