Mung bean seeding device and seeding method

The invention relates to the field of agricultural seeding instruments, in particular to a mung bean seeding device and method.The mung bean seeding device comprises two oppositely-arranged supporting frames, two fixing frames arranged in groove bodies in the outer sides of the supporting frames, a seeding disc assembly, a seed transferring assembly, a driving assembly and a vibration assembly; the vibration assembly comprises a vibration box plate which is detachably connected to the bottom of the seeding disc assembly and is used for increasing seed gaps in the vibration box plate and reducing negative pressure suction force through rotating and knocking of a knocking block of the driving assembly. According to the invention, the seed bearing sleeves in the seed suction groove sleeves are replaced, so that the seeds with different adsorption particle sizes can be favorably and adaptively replaced, the negative pressure suction of the seeds with different water absorption degrees during mung bean sowing is m
