Detailed Explanation of the Latest Management Key Points for the Fruiting Period of King Oyster Mushroom
The king oyster mushroom (Pleurotus eryngii) is a type of edible mushroom with very high nutritional value, containing extremely high levels of protein and various amino acids needed by the human body. It can enhance the body's immune system and has various effects such as reducing fat and blood pressure, aiding digestion, and resisting disease. When cultivating king oyster mushrooms, there are many growth stages, among which the fruiting period is a relatively important period in the growth of king oyster mushrooms. So how should king oyster mushrooms be managed during the fruiting period? Let's take a look together below!
1. Loosen the bag to promote budding
After the mushroom bags of the king oyster mushroom are fully covered with mycelium, the direction of mycelial growth will gradually shift to reproductive growth. After lowering the temperature of the mushroom shed to below 20°C, the bags can be loosened to promote budding. First, gently loosen the string tied tightly at the bag opening so that gaps form in the mushroom bag, improving the permeability of the bag and increasing air humidity. Then spray appropriately in the mushroom shed to increase air humidity, spraying water about 3 times a day, and then ventilate appropriately according to specific conditions, usually for about half an hour each time, keeping the air humidity at around 85%.
2. Open the bag to promote budding
When the primordia of the king oyster mushroom form small mushroom buds, open the bag appropriately to promote budding, controlling the method and size of the opening according to the conditions of the mushroom shed. The large-opening method is mainly used in mushroom sheds with suitable dryness and humidity. First turn the plastic bag over, then cut off the excess material near the culture medium. This can promote the formation of primordia. Opening the bag to promote budding is mainly to promote the growth of the fruiting body of the king oyster mushroom and shorten the budding promotion period of the king oyster mushroom.
3. Promote the growth of young mushrooms
After the primordia form small mushroom buds, the young mushroom growth period of the king oyster mushroom begins. At this time, ventilation and air permeability work in the mushroom shed should be done well to promote the differentiation of the king oyster mushroom stipe. This provides conditions for the growth of young mushrooms and can also inhibit the growth of primordia inside the bag to prevent excessive growth. If ventilation is not carried out in time, it will cause excessive differentiation of primordia and produce deformed mushrooms. The humidity of the mushroom shed should be controlled at around 90%. When watering, try to avoid water contacting the mushroom bodies, and the temperature should be controlled at around 15°C.
4. Inhibit growth of medium mushrooms
⟦NL>After the differentiation of the king oyster mushroom stipe is completed, the king oyster mushroom enters the growth period. During the growth period, the amount of ventilation should be appropriately reduced, using carbon dioxide to inhibit the development of the mushroom cap and promote the growth of the mushroom stipe. If carbon dioxide is insufficient, it will cause the cap of the king oyster mushroom to become too large and form deformed mushrooms, causing loss of commercial value. Then the temperature must not be too high. A low-temperature environment can extend the mushroom-producing period of the king oyster mushroom and improve the quality of the king oyster mushroom. Do not allow direct sunlight; mainly use scattered light, and then control air humidity at around 82%.5. Control humidity
When the king oyster mushroom grows normally and has fully grown, and is ready for harvest, attention should be paid to controlling the humidity in the mushroom shed. Prevent unsuitable humidity from affecting the final growth of the king oyster mushroom. When humidity is too high, it will cause the color of the king oyster mushroom body to darken and gradually turn black. In addition, under a high-temperature and high-humidity environment, it will cause various diseases and insect pests in the king oyster mushroom, seriously affecting yield.
The above is a brief introduction to the management key points for the fruiting period of the king oyster mushroom. The management of the fruiting period of the king oyster mushroom is very important and is directly related to the quality and yield of the king oyster mushroom. Therefore, everyone must strengthen management. That is all for today's introduction. This article is for reference only. Thank you all for reading and supporting.
