摘要：红椎是我国热带南亚热带珍优用材树种，为了挖掘和开发优异种质资源．本文以10、15、22、29、34a优良林分调查数据为据，选用胸径、树高、单株材积3个生长量指标，结合冠高比、冠幅、干形、分枝角度、侧枝粗细5个形质指标，采用5株优势木对比法和形质指标综合评分法进行优树选择技术研究。结果表明：优树胸径、树高、单株材积应分别超过优势木平均值的15％．26％、5％．7％、41％-64％，形质指标综合得分不低于6．5；选择出优树47株，入选率为40．52％。优树选择标准在实际应用中可根据林分状况在一定范围内调整。红椎人工林主要培养大径材，在选优时应首先考虑其生长量指标。同时也应注意材性、抗性的选择以保证育种群体的遗传多样性。
We studied five selective criteria of superior trees for Castanopsis hystrix A. DC of 10-34 years by the growth indexes of DBH （ the diameter at breast height）, tree height and individual volume and form quality index of stem form, height and branch. As a superior tree, the DBH, tree height and individual volume of superior tree exceed the average values of 15% -26% , 5%-7% , 41%-64% of domain tree, respectively. And at the same time, the form quality score of superior tree is not less than 6.5 of domain tree. We selected 47 superior trees from 116 candidate trees with a selected ratio of 40.52%. The chosen specification of superior tree have a certain range adjustment based on the site index. Due to big diameter of the C. hystrix A. DC, when selecting superior tree, the growth index is the first prior factor, and also the wood properties and resistance need to be considerable to insure the genetic diversity of breeding population.
