Under the comprehensive influence of light, temperature, water, air and other factors, bud-emergence is pushed on surface of substrate. During the budding period, proper temperature range of mushroom house should be at 12-15 degrees, excessive temperature results in irregular, thin and weak fruiting while too-low temperature leads to less fruiting amount and output failure. Besides, ideal relative air humidity of the house is at 80%-90%, too-low humidity goes against to bud-emergence while sundry fungus contamination is easy-appearing under over-high temperature. Cultivators could moderately enhance oxygen content through the adjustment of exhaust vents in the house.

Following this kind of mode, lush, orderly and robust mushroom buds could be most possibly obtained.
