摘　　要：大蒜形状不规则、粒大易磨损、粒多易堵塞是阻碍大蒜直立筛选与种植的关键问题。为此,通过对大蒜的品种特征、形状特征与尺寸特征等方面进行分析,寻找出大蒜芽端与根部的差异,从而为直立筛选方法的设计提供理论依据。为满足大蒜直立种植的特殊农艺要求,保证大蒜的品相质量并提高种植效率,本文提出了倾斜分隔槽排种法、触碰开关筛选法和平衡碗筛选法,并进行装置设计与各方案优劣分析,为我国大蒜播种机的优化提供参考。Irregular shape, large size, easy to wear and easy to block are the key problems to prevent garlic from upri screening and planting. For these problems, the characteristics of variety, shape and size of garlic were analyzed in present study. And the differences between the bud and the root of garlic can be found to offer theoretical basis for the design of garlic upright screening. In order to meet the special agronomic requirements of the garlic upright planting, to ensure the quality of garlic and to improve the planting efficiency, the seed metering method of the inclined separation groove, the screening method of touch switch and the screening method of balancing bowls were proposed in the this study. Devices were designed and the advantages and disadvantages of these methods were analyzed to provide some references for the optimization of the garlic planting machines in China.
