Hazy weather gives rise to great influence to people, biology as well as mushroom, the main reason is poor air flow, the discharge of carbon dioxide is accumulated in mushroom greenhouse and do terrible damage to the growth of mushrooms. The followings are the management guidelines in hazy weather.
1. Enhance temperature management: Heat preservation should be given priority in winter production, in the daytime, try to raise the temperature of mushroom greenhouse to a compatible range so that you guarantee optimal night temperature.
2. Enhance moisture management: Poor air flow is obviously evident in hazy day, mushrooms hold less moisture loss, hence reducing the frequency and amount of water-spraying in the case of guaranteeing the normal growth of mushrooms.
3. Enhance ventilation management: Ventilation is the key element in mushroom production, sometimes even if you open up air vents, air flows slowly or even remains static, in that case, the concentration of carbon dioxide rises, which directly affects the growth of mushrooms. Therefore, be sure to open the ventilator twice or three times a day and keep each time in 5-10 minutes, by doing so, the accumulated carbon dioxide could be effectively discharged, which is conductive to the normal breathing of mushrooms.
