1. The mushroom breeding site is not properly selected. If you choose to plant in the dark, in a poorly ventilated or unsanitary place, the bacterial contamination is serious, the mushrooms can't grow normally and fail; some are stubborn, but the air circulation is not smooth due to the mushrooming period, the carbon dioxide content is too high. The poisoning is affected, and it is impossible to produce mushrooms or form deformed mushrooms. Therefore, to grow mushrooms, we must first choose a place with good ventilation and good astigmatism, and keep it clean and hygienic. 2. The selection or improper preparation of culture materials. Planting shiitake mushrooms with contaminated raw materials can lead to large-scale pollution or no bacterial contamination. When the culture material is prepared, nitrogen fertilizer such as urea is excessively added to the material, and the nitrogen fertilizer is easily decomposed and released to release ammonia gas after inoculation, so that the mycelium is poisoned and cannot be normally infected. 3. The strain is not properly selected. For example, if the high temperature type is used in winter, the low temperature type is used in spring, or the bacteria that have been aged or contaminated are soaked, it is easy to cause slow or no bacteria, and the mushrooms are late or not. Therefore, when planting shiitake mushrooms, appropriate strains should be selected according to the local climatic conditions at that time, and aging or contaminated strains should not be used. 4. Poor management. Under the natural temperature conditions, the management of the mushroom is lightly ventilated. During the mushrooming period, the scattered light can meet the needs. In the mushroom house, the mushroom is not enough light, the mushroom is slowly, and can be supplemented with electric light to induce mushroom. Air humidity is an important condition for the mushrooming period. In order to increase the humidity and blindly increase the amount of water sprayed, even directly spray water on the mushroom body, some small mushrooms will be suffocated, and some grown mushrooms will also be festered by water stains. black. Therefore, during the mushrooming period, the method of hydrating should be emphasized to spray into the air as well, and at the same time, ventilation should be paid attention to avoid excessive accumulation of carbon dioxide, resulting in the formation or deformation of the fruiting body.
