In the late spring and early summer, abnormalities and treatment measures were often encountered in the cultivation of oyster mushrooms

Late spring and early summer is an ideal time for growing oyster mushrooms. However, many mushroom farmers face challenges due to improper techniques, leading to issues such as yellowing and necrosis of the mushroom sticks after fruiting, excessive acidity in the culture medium, and delayed growth after the bags are fully colonized. These problems result in lower success rates, reduced yields, and compromised quality, which directly affect economic returns. Based on years of hands-on experience and accumulated knowledge, the author has compiled a detailed analysis of the causes behind these anomalies and offers practical solutions. First, during the fruiting stage, a large number of mushrooms may die or become discolored. Yellowing, soft bases, and eventual withering often occur. This can be attributed to several factors: high temperatures above 30°C can cause blight and lead to mushroom death; if the air humidity drops below 80%, the mushrooms may shrink and wilt due to rapid water loss; poor ventilation leads to high CO₂ levels, suffocating young mushrooms; and excessive moisture can cause edema, leading to ulcers and infections. To address these issues, it’s essential to maintain proper temperature control by using well water to spray the environment and keep it under 30°C. Sheds should be shaded and ventilated properly. Air humidity should be kept around 90% by misting the floor and walls, avoiding direct sprays on the mushrooms. Proper ventilation is crucial, especially during hot periods, to ensure fresh air circulation. Watering should be done carefully—neither too much nor too little—to avoid damaging the fruiting bodies. Second, some bags may show uneven mycelium growth, with one end thriving while the other fails. This is often due to poor sterilization setup, causing uneven condensation and overwatering at one end. The solution involves improving the stove design to allow condensation to flow back into the pan, ensuring bags are not placed too close to the wall, and avoiding overcrowding. Using plastic collars or sealing methods can prevent oxygen deprivation, and inserting a hole in the bag helps avoid moisture buildup. Third, sometimes the mycelium fills the bag but no mushrooms form for a long time. This could be due to using the wrong strain type, an imbalanced carbon-to-nitrogen ratio, or excessive picking of aerial mycelium. To fix this, high-temperature strains should be used in late spring, and the carbon-nitrogen ratio must be adjusted. If necessary, the surface can be scratched and treated with glucose or triacontanol to stimulate fruiting. Maintaining proper environmental conditions, such as light, humidity, and temperature, also plays a key role. Fourth, mushroom buds may appear in the middle of the bag due to loose packing, pressure during sterilization, or improper handling. To prevent this, materials should be packed tightly, and bags must be handled with care. The culture room should provide stable conditions, with proper shading, humidity, and temperature control. Fifth, burning of the mycelium can occur when temperatures exceed 30°C, leading to overheating and death. Preventive measures include keeping the room temperature below 30°C, using cooling methods like spraying water, and monitoring internal bag temperatures. It's also important to note that the material temperature is usually 3–5°C higher than the ambient temperature. Sixth, if the mycelium doesn’t fully colonize the bag, it could be due to improper environmental conditions, such as incorrect moisture, pH, or temperature. Ensuring optimal conditions for mycelial growth, including proper lighting and nutrient balance, is essential. Selecting high-quality, viable strains also improves success. Lastly, sour or odorous culture media can indicate bacterial contamination. This may result from old or contaminated materials, excess moisture, or improper sterilization. To resolve this, fresh materials should be used, and moisture levels carefully controlled. If the media becomes sour, it should be replaced and adjusted with lime water. Deodorizing agents like ferrous sulfate and sodium bisulfate can help eliminate unpleasant smells. By addressing these issues through proper management and adjustments, mushroom farmers can significantly improve their yield, quality, and profitability.

Sterile Container

Medical sterile container is a common medical equipment, mainly used for the storage of instruments in the process of packaging, sterilization, transit, storage, etc.

The sterilization box as a whole is made of anodized aluminum, which provides anti-pressure, moisture-proof and dust-proof protection during sterilization, transportation, transit and use. The sterilization container has good sealing performance, and the sealing ring is made of silicone material:. The safety lock device is locked once to avoid misoperation.
