I. Causes of Death of Mushrooms 1. Inadequate coordination between ventilation and moisture control is a major cause of mushroom death. Straw mushrooms are aerobic fungi that require both adequate water and proper air circulation. If there's too much ventilation, the environment can become too dry, causing the mushrooms to wither. On the other hand, insufficient airflow leads to an accumulation of carbon dioxide, which can suffocate the mushrooms and lead to their death. 2. Sudden temperature changes in the mushroom house can also be fatal. Many straw mushroom farms in southern regions use foam-based mushroom houses designed to maintain stable temperatures and humidity. However, if doors are left open during typhoons, or if heating isn't provided quickly during cold spells, or if cooling isn't properly managed during heatwaves, it can create extreme conditions. Additionally, excessive watering on the floor can cause rapid cooling, leading to sudden temperature fluctuations and mass mushroom deaths. 3. Poor-quality spawn and pest infestations are another common issue. If the spawn is not used in time, it may age and lose viability, resulting in weak mycelium growth. This weak growth leads to poor nutrient absorption and low survival rates. Moreover, bacterial infections or infestations by pests like locusts can directly kill the mushrooms, even if they appear healthy at first. II. Prevention and Control Measures 1. Maintaining a proper temperature and humidity environment is crucial for successful straw mushroom cultivation. After placing the culture materials in the house, it's essential to monitor moisture levels carefully and avoid using substandard bacteria. The ideal temperature should be around 30°C. During hot weather, if the humidity drops, you can spray water on the floor and increase ventilation to cool and re-moisturize the environment. 2. When applying wheat bran (a source of nitrogen) on the surface of the spawn, it should not exceed 30%, and sometimes it may be omitted altogether. This helps reduce the risk of green mold and other bacterial or insect infestations, which can damage the crop. 3. Care must be taken during harvesting to avoid damaging the mushrooms or breaking the mycelium layer, as this can lead to dead or dying mushrooms. By being attentive at every stage of the growing process, farmers can significantly reduce the occurrence of mushroom death and improve overall yield and quality.
