Abstract: Based on the requirements for hybrid garlic seed sowing, the overall structure of an air-suction garlic seeding unit was designed, and its working principle was described. The adsorption pressure required for the seed metering device was determined to be -5 kPa. One hopper was selected for the bud reversing device, with an angle of 24.5°, and the perimeter of the insertion device measured 600 mm. The optimal combination of parameters for sowing involved a negative pressure of -5 kPa and a forward speed of 1 km/h at the third level. Under these conditions, the qualified rate of individual sowing reached 84.26%, while the missed sowing rate was 7.12%, meeting the agronomic requirements for garlic seed sowing. Field experiments validated the theoretical analysis and bench tests, providing a solid foundation for the future production and promotion of garlic sowing units.
