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.

根据杂交大蒜种子的播种要求，设计了吸气式大蒜播种单体的整体结构，并描述了其工作原理。确定种子计量装置所需的吸附压力为-5 kPa。为磷芽交换装置选择了一个料斗，角度为24.5°，插入装置的周长为600 mm。播种的最佳参数组合为负压-5 kPa，前进速度为1 km/h，设定在三级档位。在此条件下，单粒播种的合格率达到了84.26%，漏播率为7.12%，满足了大蒜种子播种的农艺要求。田间试验验证了理论分析和台架试验的准确性，为大蒜播种单体的未来生产和推广奠定了基础。
