Light conditions Light is not only an important way to increase temperature in winter, but also an important way to improve the yield and quality of oyster mushrooms. The lighting time should be determined according to the planting room temperature and weather conditions. If the planting room has good heat preservation and the night temperature is above 5℃, the lighting time should be extended as much as possible. The shed can open the grass thatch to ensure light transmission. The clarity of the film, suitable late cover, etc.; if the planting room temperature is low and the heat preservation is poor, the daylight time should be shortened. If it is sunny, the planting room temperature is below 5℃, and the film can be covered to receive sunlight, which can increase the temperature and increase the light time.

Rain and snow should also enhance the planting room. If there is no direct light, scattered light is fine. In a planting room with strong sunlight, the fruit body of oyster mushroom is dark in color, thick in flesh, good in toughness, good in quality, and yield can be improved.

Moisture conditions In winter, the temperature is low, the evaporation in the shed is small, the mycelium respiration is reduced under low temperature conditions, the water consumption is also reduced, and the number and time of uncovering the film are also reduced, which is destined to be relatively stable in the shed. . Therefore, when planting Pleurotus ostreatus in winter, spray water properly and not too much.

For places where water is needed and the planting room has a guaranteed temperature, it is generally sufficient to spray water once a day or two. Ventilate as much as possible when spraying water, and do not spray water in a closed planting room.

Pleurotus ostreatus is cultivated in winter with ventilation. The ventilation should be frequent but not large. When ventilation is required, it should also be carried out under the premise that the temperature is guaranteed, and the ventilation time should be reduced as much as possible. Instead, frequent ventilation and small air should be used. The ventilation can be 3 to 4 times a day, which is about 30 minutes. If the planting room is small and the shed with limited ventilation conditions, it should be ventilated 8 to 10 times a day for about 20 minutes, and try to achieve the effect of ventilation in every corner.

Temperature regulation Temperature is an important factor for cultivating Pleurotus ostreatus in winter, which can affect the production and normal growth of mushroom buds. During the fruiting period, the temperature of the planting room should be kept at about 8℃~15℃. If the temperature before budding is too low or the temperature difference is too small, it is difficult to form mushroom buds. When the temperature is too low after budding, the fruit body will basically stop growing. Warming methods include: natural light, stove fire, and grass thatch. It should be noted that when heating the stove, you should avoid directly lighting a fire in the planting room to prevent oxygen consumption, increase carbon dioxide content, and affect the growth of oyster mushrooms.
