Disclosed is a cold plasma seed treatment device. The device comprises a vacuum apparatus, an electric discharging apparatus, and a transport apparatus. The electric discharging apparatus and the transport apparatus are disposed in the vacuum apparatus. The vacuum apparatus is provided with a tube feeding hole and a tube discharging hole. The cold plasma seed treatment device further comprises a feeding apparatus and a discharging apparatus. The feeding apparatus comprises a first feeding hopper and a second feeding hopper. Each of the first feeding hopper and the second feeding hopper is provided with a feeding cover, a vent valve of the feeding hopper, a discharging hole of the feeding hopper, and a vacuuming butterfly valve of the feeding hopper. Each of the discharging hole of the feeding hopper of the first feeding hopper and the second feeding hopper and the tube feeding hole are separately connected to a three-way pipe by using a butterfly valve of the feeding hopper. Each vacuuming butterfly valve of the feeding hopper of the first feeding hopper and the second feeding hopper are connected to a first vacuuming pump group. The discharging apparatus comprises a first discharging hopper and a second discharging hopper. The present invention is suitable for treating various crop seeds and is low in treatment cost, high in speed and pollution-free, resistance capabilities of crops, such as drought resistance and resistance to pest and disease damage are enhanced, and the yield is remarkably increased.
