Production Management Methods and Technical Key Points for the Growing Period of Oyster Mushrooms

After the large-scale formation during the mulberry stage and the brief coral stage, the mushroom bodies gradually enlarge and enter the growing period. At this time, management should be strengthened so that the mushroom bodies differentiate and mature within 5-7 days. Specific management measures:

① Ventilation. To prevent deformed or rotten mushrooms caused by excessive stale air in the room, ventilate 3-4 times daily to supply fresh air.

② Moisture retention. Adequate air humidity is an important condition for the enlargement of the mushroom bodies, so mist water should be sprayed in the room 4-5 times daily. However, avoid water accumulating on the caps, so as to prevent curling. The relative air humidity should be maintained above 90%, and if it drops below 75%, it should be raised again by spraying. During spring management, the climate is dry and more spraying should be done; in winter, an iron pot can be placed on the stove to boil water; in autumn, there is more rain and excessive moisture should be prevented. If the surface of the mushroom board is dry, a small spoon can be used to sprinkle clean water on it; it must not be sprinkled directly on the mushroom bodies.

③ Early-maturing individuals should be harvested in time, and the method of harvesting the large ones while leaving the small ones can be adopted. As the mushrooms gradually mature, harvest them successively, and at the same time the air humidity should also gradually decrease.
