摘　　要：2022年1月开展6个种源杉木2年生幼林生长量测定。通过试验观察不同种源杉木幼林生长表现,进行幼林方差分析和聚类分析等对比研究。通过分析,可将6个种源幼林分为3个类群:A类群是官庄种源和华桥种源具有较高的树高和较粗的地径生长较快;B类群是将乐种源和尤溪种源生长中等;C类群是卫闽种源和洋口种源生长较慢。In January 2022,the growth of 2-year-old young Chinese fir from 6 provenances will be measured.The growth performance of young Chinese fir stands of different provenances was observed through experiments,and the variance analysis and cluster analysis of young Chinese fir stands were conducted.Through analysis,the young forests of 6 provenances can be divided into 3 groups:Group A is Guanzhuang provenance and Huaqiao provenance,which have higher tree height and thicker ground diameter and grow faster;In group B,the provenances of Jiangle and Youxi grew moderately;Group C is the Weimin provenance and the Yangkou provenance which grow slowly.
