4种壳斗科常绿树种容器苗造林早期生长比较

Comparison on the Early Growth of Container Seedlings Afforestation of 4 Fagaceae Evergreen Species

进行4种壳斗科常绿树种容器苗造林试验。根据造林保存率、胸径、树高、冠幅、变动系数值,采用方差分析、多重比较、系统聚类方法,比较4树种早期生长状况。结果表明,青冈的保存率最高,表现出较强的环境适应能力,但其它生长指标差于另3种树种。综合比较反映,米槠表现最优,小叶青冈、鹿角栲表现居中,青冈次于前3种树种。

Choose four evergreen species of Fagaceae to take container seedling afforestation test. According to afforestation preservation rate, diameter at breast height, tree height, crown width, coefficient of variation values, using analysis of variance, multiple comparisons, system clustering method, the early growth of four species was compared. The results showed that preservation rate of Cyclobalanopsis glauca is the highest, showed strong environmental adaptive capacity, however, other growth indicators worse than the other three species. Comprehensive comparison of the results showed that Castanopsis carlesii manifestations were best, performances of C. myrsinaefolia, C. lamontii were at the middle level, C. glauca was inferior to the front three species.
