Mushroom quality detection device

The invention belongs to the technical field of mushroom quality detection, and particularly relates to a mushroom quality detection device which comprises a cultivation instrument, a cultivation cover is arranged at the top of the cultivation instrument, a feeding hole is formed in the top surface of the cultivation cover, a bearing plate is inserted into the feeding hole, a bearing groove is formed in the top surface of the bearing plate, and the bearing groove is communicated with the cultivation cover. The receiving groove is used for placing a detection card; according to the mushroom quality detection device, the bearing plate is arranged, the bearing groove is formed in the top face of the bearing plate, a detection card is placed in the bearing groove during detection, then the feeding hole is blocked through the cover plate, and in the process that a worker takes out the detection card in the bearing groove, air in the cultivation cover is blocked by the bearing plate and does not make contact with t
