What are the environmental requirements for the growth of the white king oyster mushroom
The white king oyster mushroom is a relatively precious mushroom species in China, and it is distributed throughout the country. Because there is a relatively large market demand, quite a lot of people grow the white king oyster mushroom. However, when growing the white king oyster mushroom, we need to pay attention to its environmental requirements for growth. So what exactly are they? Below, the editor brings you the environmental requirements for the growth of the white king oyster mushroom. Let's take a look together!
1. Temperature requirements
The white king oyster mushroom is a low-temperature type of mushroom. The suitable temperature for mycelial growth is generally around 5-30°C. However, its optimal growth temperature should be around 23°C. If it is below 5°C, its growth rate will drop noticeably. But if it is above 35°C, the mycelium will stop growing. If the mycelium is to after-ripen, then it needs about 30-45 days to reach physiological maturity. The temperature should be controlled at around -3-15°C, and it is best to keep it within the range of 7-12°C, so as to ensure normal differentiation of the fruiting body. Then, during the fruiting stage, the optimal temperature is around 13-18°C.
2. Moisture requirements
The white king oyster mushroom also has very high moisture requirements during growth. The water-to-substrate ratio should be controlled at around 1:1, and the moisture of the culture substrate must be kept at at least 65%. During the growth period of the white king oyster mushroom fruiting body, the air humidity should be controlled at around 85%. Remember that the humidity must not be too high, otherwise yellow mushrooms will appear, affecting sales. If the temperature is 6-7°C, then the humidity must not be too low, otherwise cracking of the mushroom cap will occur. Finally, the water content of the white king oyster mushroom fruiting body is actually relatively low. Generally, after harvesting, it can be stored for about two weeks in a 15°C environment.
3. Light requirements
The white king oyster mushroom does not have a great demand for light during growth. Under normal circumstances, during the spawn-running stage, it can grow normally even under dark culture. However, during the stage of fruiting body growth and development, a certain amount of scattered light is still needed. Especially during the growth of the fruiting body, if it is completely in a dark environment, then the differentiation of the fruiting body will be seriously affected. Therefore, it is mainly necessary to maintain about 13 hours of scattered light each day. However, because varieties differ, the demand for light also differs to some extent. If the light is too weak, it will lead to phenomena such as deformed fruiting bodies and overly small mushroom caps.
4. Oxygen requirements
Oxygen is also one of the main environmental requirements for the growth of the white king oyster mushroom. The white king oyster mushroom is an aerobic type of mushroom. Whether it is the mycelium or the fruiting body, both need sufficient fresh air. Therefore, when cultivating the white king oyster mushroom, ventilation and air exchange work is very important. If the indoor carbon dioxide concentration exceeds 0.4%, then it will affect the formation of the white king oyster mushroom primordia and cause deformed mushrooms. Therefore, no matter which growth stage the white king oyster mushroom is in, attention must be paid to ventilation, and at the same time attention must be paid to maintaining mild conditions, and its temperature and wind speed should be harmonious and consistent.
The above is a brief introduction to the environmental requirements for the growth of the white king oyster mushroom. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
