摘　　要：为了研究并制定北苍术种苗质量标准,以不同产地北苍术种苗为材料,观察并测量北苍术种苗的侧根数、根茎长、根茎粗、种苗长等各项指标性状。将实验数据进行收集、整理后,采用相关性分析法、系统聚类分析和K-均值聚类分析等多元统计分析方法进行质量分级,并制定出北苍术种苗质量分级标准。北苍术种苗划分为三个等级:Ⅰ级种苗:侧根数≥27条,根茎长≥2.42 cm,根茎粗≥2.11 cm,种苗长≥24.80 cm,种苗粗≥0.47 cm,鲜重≥9.08 g;Ⅱ级种苗:侧根数≥15~<27条,根茎长≥1.92~<2.42 cm,根茎粗≥1.50~<2.11 cm,种苗长≥18.94~<24.80 cm,种苗粗≥0.35~<0.47 cm,鲜重≥4.96~<9.08 g;Ⅲ级种苗:侧根数≥9~<15条,根茎长≥1.12~<1.92 cm,根茎粗≥0.88~<1.50 cm,种苗长≥13.52~<18.94 cm,种苗粗≥0.18~<0.35 cm,鲜重≥1.73~<4.96 g。To study and establish the quality standard of A.chinensis seedlings,the number of lateral roots,rhizome length,rhizome diameter and seedling length of Atractylodes aureus seedlings from different areas were observed and measured.After collecting and sorting out the experimental data,multivariate statistical analysis methods such as correlation analysis,systematic cluster analysis and K-mean cluster analysis were used for quality classification,and the quality classification standards of A.chinensis seedlings were established.A.chinensis seedlings were divided into three grades:GradeⅠseedlings:number of lateral roots≥27,rhizome length≥2.42 cm,rhizome diameter≥2.11 cm,seedling length≥24.80 cm,seedling diameter≥0.47 cm,fresh weight≥9.08 g;GradeⅡseedling:the number of lateral roots was≥15-<27,rhizome length was≥1.92-<2.42 cm,rhizome diameter was≥1.50-<2.11 cm,seedling length was≥18.94-<24.80 cm,seedling diameter was≥0.35-<0.47 cm,fresh weight was≥4.96-<9.08 g;GradeⅡseedling:the number of lateral roots was≥9-<15,rhizomes≥1.12-<1.92 cm in length,rhizomes≥0.88-<1.50 cm in diameter,seedlings≥13.52-<18.94 cm in length,seedlings≥0.18-<0.35 cm in diameter,fresh weight≥1.73-<4.96 g.
