摘　　要：采用逐步聚类分析方法,对150 d铁力木容器苗进行分级研究,将苗木分为3级(1级苗,苗高≥19.4 cm,地径≥0.25 cm;2级苗,19.4 cm>苗高≥12.3 cm,0.25 cm(地径≥0.16 cm;3级苗,苗高(12.3 cm,地径(0.16cm).方差分析及不同级别苗木造林试验表明,该分级标准是可行的.对铁力木幼林进行NPK和过磷酸钙施肥试验结果表明,施用NPK肥能明显促进幼林生长.Adopting stepwise clustering analysis,the classification of 150-day Mesua ferrern L.container seedlings was studied.Three classes,i.e.I,Ⅱand Ⅲ,was preliminarily categorized,among which seedlings with height ≧ 19.4 cm and base diameter ≧0.25 cm were clustered in the Class I,seedlings with 19.4 cm﹥height ≧ 12.3 cm and 0.25cm ﹥base diameter ≧ 0.16 cm were in Class Ⅱ,and seedling with height ﹤12.3 cm and base diameter﹤0-16 were in Class Ⅲ.The results of variance analysis and plantation experiments showed that the seedling classification was practical and could guide the seedling production and cultivation.Furthermore,the results of applying fertilization of NPK and calcium superphosphate on the young stand of Mesua ferrern L.indicated that NPK fertilization could obviously promote the growth.
