1.Temperature: The oyster mushroom belongs to the low-temperature type bacterium, the mycelial growth temperature is 5-28 °C, the most suitable growth temperature is 23-26 °C, the suitable temperature of the fruiting body is 8-22 °C, the temperature of the mushroom needed for different cultivars different. The production season should be arranged according to the optimum temperature requirement of the fruiting body. During the cultivation process, the weather should be changed. Temperature adjustments should be taken in time. When the temperature decreases, the mushroom house can be tightly closed. If necessary, a plastic film can be used. Close the mouth of the cultivation bag. When the temperature rises, especially when the temperature exceeds 25 °C, the cover of the mushroom house (shed) can be opened sooner or later, and the humidity and the relative humidity of the ground in the mushroom house (shed) can be increased to facilitate cooling. At the same time artificially increase the temperature difference between day and night, promote hyphae kinks, as soon as possible to form the original base.
2. Humidity: when the medium moisture content is 65-70%, the water content is too low to inhibit the growth of mycelium. Too high water content can easily cause bacteria, yeasts and other bacteria to multiply, and the mycelial growth stage does not require external air temperature. Strict, generally controlled at 65% or less, later increased to 70-80%%, fruiting phase requires culture material moisture content of 70%, air relative humidity of 85-90%. The moisture management of the mushroom house (shed) must be based on the moisturizing properties of the mushroom house (shed), and the climate change should be controlled flexibly. The water should be sprayed in less rainy days, more water should be sprayed in sunny days, and the air humidity in the mushroom house (shed) is maintained. At 85-95%. According to the development of fruiting body to grasp the moisture, as long as the period of buds to keep the moisture of the cultivated material surface, with the growth of the fruiting body should be appropriately increased, but the mushroom can not maintain high humidity within a long time State, relative humidity should not exceed 95%, pay attention to ventilation and humidity.
3, ventilation: ventilation, give enough oxygen, continue to emit carbon dioxide. In the stage of mycelial growth, the lack of oxygen in the mushroom house (shed) and the high concentration of carbon dioxide will inhibit the growth of the mycelium. If the concentration of carbon dioxide is too high for a long time, it will cause the hyphae to shrink and degenerate, and even contaminate the bacteria. Sufficient oxygen is needed during the growth of the fruiting body. If the mushroom house is not ventilated or ventilated for a long period of time, it may be prolonged. Therefore, combine water spray during fruiting, and always ventilate.
4. Light: Hydrangea, like other edible fungi, does not have chlorophyll and does not require direct light. Mycelial growth is slow under light conditions, and strong light will inhibit mycelial growth and development. The formation phase of the fruiting body is very sensitive to light and must have some scattered light. There is proper scattered light during mushrooming, but the light inside the mushroom house (canopy) must not be too strong and direct sunlight is not possible.
5, pH: The pH value of the culture medium will affect the activity of the acid in the mycelium cells, the permeability of the cell membrane and the absorption capacity of metal ions. The suitable pH value for agaricus is 6.0-7.0.
