| 摘 要： | 对位于广东省仙菊林场的一片35hm^2的20年生火力柚实生人工林，设立了8个标准地，开展了每木调查。结果表明，林分平均胸径和树高分别为16．56和14．79m，林分内个体间差异极大，存在着一批优良木，经去劣疏伐可将林分改造成母树林。文中给出了选择优良木的不同标准作为林分疏伐的依据。此外还分析了生长与形质、叶形性状的相关关系，为该树种的遗传改良和间接选择提供参考。 |

| Abstract: | A 20 years old plantation of Michelia macelurei,with the area of 35 hm 2, situated in Xianju Forest Farm,Guangdong Province,was surveyed by setting 8 sample plots.As the results,the overall mean diameter breast-high of the whole stand was 16.56?cm and the mean height was 14.79?m. There was extremely significant difference between individual trees within the stand.Numbers of fine trees existing in the stand provided the basis of rouging and transforming the stand to be a seed stand.Different criterions of selecting fine trees were raised.Besides,correlation between characteristics of growth,form quality and leaf shape was analyzed.This can be referred by the genetic improvement and the indirect selection of the species. |
| Keywords: | Michelia macelurei plantation seed stand correlation of characteristics |
