Abstract

To address the issue of seed filling in mechanical seed meters for different varieties of adzuki beans and to provide a basis for designing the shape and size of seed metering plate holes, a statistical analysis of the physical parameters of seeds from 10 adzuki bean varieties with significant morphological differences was conducted. The three-axis dimensions (length, width, and thickness) and the equivalent diameter of the seeds were found to approximately follow a normal distribution. The distribution and dispersion of each physical parameter were analyzed. A linear correlation analysis was performed between the equivalent diameter and the hundred-seed weight, showing a consistent overall trend. By measuring the hundred-seed weight, the relative equivalent diameter was determined, which was then used to select the appropriate seed metering plate diameter. The linear correlation coefficient analysis of the three-axis dimensions of different varieties indicated that, when modeling adzuki bean seeds for simulation, either the width or thickness could be selected as the primary dimension based on specific conditions.

为解决红小豆机械式排种器对不同品种红小豆的充种问题，提供排种盘型孔结构设计参数依据，选取形态差异较大的10种红小豆种植品种的种子物理参数进行数据统计分析。种子的三轴尺寸长、宽、厚及均径均近似服从正态分布，分析确定了各物理参数的分布离散情况，均径与百粒重整体变化趋势基本一致并进行线性相关分析，通过测量百粒重得出相对均径从而选择排种盘直径，不同品种三轴尺寸间线性相关系数分析结果表明，仿真红小豆种子建模时可根据具体情况选取宽或厚作为主尺寸。
