After finding that spawns are fully grown in fungus sacks, people should keep moderate temperature and humidity to guarantee successful fruiting, keep the temperature of cultivation house in between 12 and 18 degrees, keep the humidity in between 90% and 95%, people could spray water on the ground of space. In general, mushroom buds will appear after 10 to 15 days. During this period, people should guarantee good condition of bag-opening after the formation of primordium and before the occurrence of mushroom buds. The approaching speed of mushroom buds has much to do with temperature. Fruiting will be quick in the temperature of 12 to 16 degrees, too early bag-opening will affect the amount of fruiting and quality, therefore, it is best for people to open bag when spawns haven’t kink. In order to extend the length of preservation, people could control the humidity in between 80% and 85% in 2 to 3 days before picking. During the process of management, people shouldn’t spray water directly on mushroom bodies, this behavior should be avoided, especially in high temperature, or it will cause yellow mushroom bodies, pollution and bacterias. If sporocarps are biggish, the phenomenon of malformation will happen when opening bag. The phenomenon of atrophy and rot will happen in serious conditions, therefore, when cultivating King oyster mushroom, people should open bags when finding that primordium has formed and mushroom buds have appeared.
1. Temperature control: the temperature of mushroom house directly affects the formation of primordium and the growth of sporocarps. When the temperature is below 8 degrees, it will be hard for primordium to form. When the temperature rises to 12 degrees, original sporocarps will grow quickly, qualities will loss, little mushroom buds stop growing and begin to atrophy, the differentiation of primordium will stop. When the temperature is higher than 21 degrees all the time, original sporocarps and the surface of substrate will become soft, atrophic and rotten. In a word, during the cultivation process, people should keep the temperature of mushroom house in between 12 and 18 degrees.
2. Humidity control: the humidity of mushroom house should be controlled in between 85% and 95%. In too low humidity, sporocarps will become atrophic and will stop growing, primordium will become cracked and undifferentiated. What’s more, it is improper for people to spray water directly on sporocarp, or it will cause yellow sporocarps, which can affect quality and the phenomenon of rot in serious condition.
3. The adjustment of air: fresh air is needed during the growth period of sporocarps. So, people should give frequent ventilation to mushroom house. In poor ventilation, sporocarps are hard to grow, little sporocarps will stop growing and become atrophic. The phenomenon of rot in sporocarps is easy to happen under the condition of high temperature and high humidity, therefore, people should keep good ventilation of mushroom house.
