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

Abstract

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 according to the parametric variation rules in different stages of growth and development of the golden mushrooms, and the operating time of the internal circulation system is controlled.

Description

Technical field: [0001] The invention relates to a method for regulating ventilation and internal circulation of an industrial cultivation room of Flammulina velutipes, in particular to a method for artificially regulating factors such as environmental temperature, humidity, and air required for the growth and development of Flammulina velutipes. Background technique: [0002] At present, there are two industrial production methods of Flammulina velutipes: one is the industrial production mode of Japanese-style Flammulina velutipes. However, the requirements for facilities and equipment are high, and the input cost is very high. This method is basically not suitable for my country's national conditions, and it is difficult to popularize and apply; The process is the bag planting regeneration method, which organically combines the traditional bag planting process of Flammulina velutipes with the refrigeration technology of cold storage to form a factory production mode of Flamm...

Problems solved by technology

[0004] After research and analysis, the temperature, air relative humidity, O 2 and CO 2 If the concentration is transferred by diffusion in still air, the transfer speed is slow, among which CO 2 The specific gravity is heavier than air, and it will sink to the bottom of the room. Therefore, there are differences in the degrees of each factor in the indoor space, which cannot meet the uniformity requirements.
