Latest Management Techniques and Methods Tutorial for the Oyster Mushroom Fruiting Period
Oyster mushroom is one of our common edible fungi, 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 managed improperly, it is very easy for phenomena such as failure to bud, ongoing growth, and infection by pests and diseases to occur. So how should oyster mushrooms be managed during the fruiting period? Let's take a look together.
1. Adjust 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 adjust temperature and humidity. For oyster mushroom varieties cultivated in autumn and winter, their 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, it is not suitable to irrigate frequently, so as to avoid excessive humidity in the mushroom shed, and it is even more unsuitable to spray too much water at one time. Especially at night, when spraying water, pay attention to spraying a fine mist of water, and it is not suitable to spray water directly with a hose.
2. Increase scattered light
After oyster mushrooms fruit, they have certain light requirements. In an environment with insufficient light, the stems of the fruiting bodies will grow too long while the caps become smaller, reducing their marketability 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. Correct management is to ensure that the mushroom shed has bright scattered light. However, it should not be exposed to direct sunlight, because direct sunlight leads to fewer mushrooms fruiting at both ends of the mushroom bag and increases fruiting in the middle, thereby affecting the quality of the oyster mushrooms.
3. Prevent diseases
In winter, the temperature is relatively low and there are very few insect pests. During cultivation, the main thing that needs to be prevented 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 occurs, small mushroom buds begin to die in large numbers, gradually turning yellow and dry. For dry rot, spray prevention is best. After the disease occurs, drugs such as Mushroom Nemesis, No. 2 Warthog, Mold Spot Net, and Baoqing can be sprayed, and the effect is better when used alternately.
After bacterial spot disease occurs, small yellow-brown spots form on the mushroom caps. As the disease develops, the spots gradually expand and merge into large spots, thereby affecting the marketability 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.
