1. Improper temperature of environment and material: Ill-suited range of fruiting temperature gives rise to the normal mushroom fruiting.
2. Poor ventilation in mushroom greenhouse: Poor oxygen supply and too high carbon dioxide concentration go against to fruiting, serious oxygen deficit brings about large amount of withered and dead buds.
3. Improper method of spraying: The compost accumulates excessive water after you spray excessive amount of water or directly spray water on compost and tiny mushrooms, under that circumstance, spawns become dead and choking while the occurrence rate of bacterial disease hikes.
4. Halfway sterilization on compost and greenhouse.
