| 为探索食用葵花籽清选、分级、选种、定价的理论依据，完善建立葵花籽的离散元法分析模型，对食用葵花籽的主要尺寸及均齐性进行了分析。选择内蒙古自治区主栽的3个品种食用葵花籽（1013、SH361、SH363）为研究对象，使用统计学方法，以籽粒的三轴尺寸(长度、宽度、厚度)、平均径（算术平均径、几何平均径）、百粒重为指标，分析葵花籽三轴尺寸的统计分布特性、均齐性以及平均径与百粒重的关系，并按宽度对葵花籽进行了清选分级试验。结果表明：不同品种葵花籽的三轴尺寸均服从正态分布并存在线性相关，且总体上存在显著性差异；葵花籽的均齐性存在差异且其几何平均径、算术平均径与百粒重的变化趋势一致；1013品种选用圆孔筛10 mm和8 mm规格，SH361和SH363品种选用圆孔筛10 mm和8.5 mm规格时，分级效果满足要求。 |

| In order to explore the theoretical basis for cleaning, grading, selection, pricing of sunflower seeds, and improve the discrete component analysis model of sunflower seeds, the main dimensions and homogeneity of edible sunflower seeds were analyzed. The three typical edible sunflower seeds (1013, SH361, SH363) planted in Inner Mongolia Autonomous Region were used as research objects, and the statistical distribution characteristics of the three-axis sizes, homogeneity and relationship between average diameter and hundred-grain weight of the sunflower seeds were analyzed with the three-axis size(length, width and thickness), mean size(geometric mean diameter, arithmetic mean diameter) and hundred-grain weight as indexes. The width grading test of sunflower seeds was carried out. The results showed that the three-axis sizes of different varieties of sunflower seeds followed a normal distribution and were linearly correlated with significant differences in general. The homogeneity of sunflower seeds was different, and its geometric mean diameter, arithmetic mean diameter and hundred-grain weight had the same changing trend. When round hole sieves of 10 mm and 8 mm were used for 1013, and round hole sieves of 10 mm and 8.5 mm were used for SH361 and SH363, the grading effect could meet the requirement. |
