Detailed Explanation of Key Management Techniques for Oyster Mushroom During the Fruiting Period
Oyster mushroom is one of the common edible fungi we encounter, and when cultivating oyster mushrooms, winter is exactly the time for fruiting. Management during the fruiting period is an important part of achieving high quality and high yield in oyster mushrooms. If management is improper, problems such as failure to produce pins, ongoing growth, and infection by pests and diseases can easily occur. So how should oyster mushrooms be managed during the fruiting period? Let's take a look together.
1. Regulating temperature and humidity
In winter, the temperature continues to drop. Although oyster mushrooms have a very wide range of temperature adaptability, they inevitably suffer from the effects of low temperatures. Therefore, the first thing to do in management is to regulate temperature and humidity. For oyster mushroom varieties cultivated in autumn and winter, the fruiting temperature is generally between 5-30 degrees. Once the temperature is below 5 degrees, the fruiting bodies grow slowly or even stop growing, so the temperature in the mushroom shed must not be lower than 5 degrees, but it should also not be too high, and is best kept at 10-12 degrees. In humidity management, do not irrigate frequently, so as to avoid excessively high humidity in the mushroom shed, and even more so, do not spray too much water at one time. Especially at night when spraying water, pay attention to spraying a fine mist, and do not spray water directly with a hose.
2. Increasing scattered light
After oyster mushrooms fruit, they have certain light requirements. In an environment with insufficient light, the fruiting bodies' stems will grow too long while the caps become smaller, reducing their commercial quality and affecting the selling price. Many growers think this is caused by poor ventilation or other improper management. The light in the mushroom shed should not be too strong. The correct management approach is to ensure that the mushroom shed has bright scattered light. However, direct sunlight is not suitable. Direct sunlight will lead to less fruiting at both ends of the mushroom bag and increase fruiting in the middle, thereby affecting the quality of the oyster mushrooms.
3. Preventing diseases
In winter, when the temperature is relatively low, there are very few pests, and the main thing to prevent during cultivation is disease. Generally speaking, the main diseases during the fruiting period are dry rot and bacterial spot disease. Dry rot occurs at a relatively high frequency in old mushroom sheds. After the disease develops, small mushroom pins begin to die in large numbers and gradually turn yellow and dry out. For dry rot, spray prevention is best. After the disease develops, drugs such as Mushroom Nemesis, No. 2 Warthog, Mildew Spot Net, and Baoqing can be sprayed, and alternating use gives better results.
After bacterial spot disease develops, small yellow-brown spots form on the mushroom caps. As the disease progresses, the spots gradually expand and merge into large spots, thereby affecting the commercial quality of the oyster mushrooms. To prevent this disease, in addition to spraying a fine mist and controlling humidity, attention should also be paid to promptly removing diseased oyster mushrooms and promptly spraying fungicides.
