Corn breeding device and breeding method for improving germination rate

The invention belongs to the technical field of corn breeding, and particularly relates to a corn breeding device and a corn breeding method capable of improving germination rate, aiming at solving the problem that the illumination intensity and time suffered by corns at different positions are different because lamps used in experiments cannot uniformly irradiate on each glass plate. Therefore, the corn germination at different positions is influenced, the corn germination rate is reduced, and the inaccurate data result of the germination rate is indirectly caused; comprising a breeding box, a mounting plate is arranged on the breeding box, and the mounting plate and the breeding box are connected through bolts; a driving motor is mounted on the mounting plate; the driving motor is connected with the angle overturning and pitching prevention assembly; the angle anti-tipping assembly comprises a driving square block arranged at the output end of the driving motor; by means of the angle turning-over-preventing
