为了制定1年生桢楠容器苗的分级标准，提高桢楠苗木种植成活率，采用系统聚类分析方法，建立以苗高和地径为质量分级指标的分级体系，获得3级分级标准，即Ⅰ级苗：苗高≥38 cm，地径≥0.65 cm；Ⅱ级苗：38 cm＞苗高≥31.7 cm，0.65 cm＞地径≥0.56 cm；Ⅲ级苗：苗高＜31.7 cm，地径＜0.56 cm。

In order to improve the survival rate of planting seedlings of Phoebe zhen-nan, the grading standard for one-year-old container seedlings of Phoebe zhennan was developed by using cluster analysis. The results showed that the quality of Phoebe zhennan container seedlings could be estimated from seedling height and ground diameter. The Phoebe zhennan container seedlings were divided into 3 grades: Grade 1 (seedling height ≥ 38 cm; ground diameter ≥ 0.65 cm), Grade 2 (31.7 cm ≤ seedling height < 38 cm; 0.56 cm ≤ ground diameter < 0.65 cm) and Grade 3 (seedling height < 31.7 cm; ground diameter < 0.56 cm).
