Method for automatically regulating ventilation and internal circulation of industrialized cultivation house for gold needle mushroom

The invention relates to a bag-cultivation industrial culture process for golden mushrooms in China, and an optimization, regulation and control technology is adopted for the environment temperature, the environment humidity and the air concentration which are required for the growth and the development of the golden mushrooms. On the basis of the prior golden mushroom industrial culture conditions, and by changing the cold air flow direction and the air speed of an air cooler, the cold air cannot directly blow to a fungus pack on the top bed; three axial fans are additionally arranged indoors to form an indoor air internal circulation system; the facilities are optimized, regulated and controlled, a circular ventilation opening is arranged on the wall facing to the center at the rear part of the air cooler, and an air throttle for controlling the opening and the closing is installed at the outer side; microcomputer time controllers are installed for a fan and a ventilation fan, the start-stop time is set acc
