摘　　要：对忽地笑种球的主根数、围径、基盘直径及重量等指标进行测量,利用SPSS及图形软件进行相关数据分析;记录盆栽苗开花指标。结果表明,通过相关性分析、主成分分析、聚类分析等方法初步将忽地笑种球分为五个等级,一级球,围径>16 cm;二级球,围径14~16 cm;三级球,围径12~13.9 cm;四级球,围径10~11.9 cm;五级球,围径8~9.9 cm;不同级别种球在外观形态上存在围径、基盘、重量等方面的大小差异,各级别种球均具有分球特性,分球方式为侧分球;不同级别种球对花期、开花时长、葶基粗、葶颈粗、花瓣宽及雄蕊长等指标无明显影响,对开花率、结实率、葶长、花径有不同程度影响,且与种球围径呈正相关。研究得出的分级标准科学合理,可用于实际生产,用于林下经济林花种植时尽量选择一、二级种球,以达到林下经济林药+林花种植模式的效益最大化、景观最佳化。The number of taproots, girth diameter, base plate diameter and weight of the bulbs were measured, and SPSS and graphics software were used to analyze the relevant data;the flowering indicators of potted seedlings were recorded. The results showed that, through the methods of correlation analysis, principal component analysis, cluster analysis, etc., the seed bulbs were preliminarily divided into five grades: the first-grade balls, with a circumference more than 16 cm;the second-grade balls, with a circumference of 14-16 cm;the third-grade balls. Balls, with a circumference of 12-13.9 cm;Grade-4 balls, with a circumference of 10-11.9 cm;Grade-5 balls, with a circumference of 8-9.9 cm;different grades of balls had differences in appearance and shape in terms of circumference, base, and weight. The bulbs of all grades had the characteristics of dividing the bulbs, and the bulbs were divided by side. It had different effects on flowering rate, seed setting rate, scape length and flower diameter, and was positively correlated with seed bulb circumference. The grading standards obtained from the research were scientific and reasonable, and could be used in actual production. When used for the planting of economic forest flowers under the forest, we could try to choose the first and second seed bulbs to maximize the benefits and the best landscape of the under forest economic forest medicine + forest flower planting model.
