摘要:
采用逐步聚类分析方法，对铁力木容器苗苗木的分级标准进行了探讨。提出了以苗高和地径作为该树种苗木分级的质量指标，并得出铁力木苗木的3级分级标准，即 Ⅰ级苗 树高≥19.4 cm，地径≥0.25 cm、Ⅱ级苗 19.4 cm>树高≥12.3 cm，0.25 cm>地径≥0.16 cm、Ⅲ级苗 树高<12.3 cm，地径<0.16 cm。西北林学院学报21卷第1期杨斌等铁力木苗木分级研究
Abstract:
The standard of seedling grading of Mesua ferrea L. was studied by using the methods of gradual cluster analysis. Seedling height and basal diameter were proposed as the main indexes of quality for seedling grading of this species. The following standards were produced for seedlings of the first to the third grades. The seedlings with the height of 19.4cm or above, basal diameter of 0.25cm or above were classified as grade one, those with height lower than 19.4cm but higher than or equal to 12.3cm, basal diameter lower than 0.25cm but higher than or equal to 0.16cm were classified as grade two, those with height lower than 12.3cm and basal diameter lower than 0.16cm were classified as grade three.
