| 摘 要： | 应用多元方差分析和多重比较对红锥不同类型苗木在不同立地条件下造林成效进行对比分析,结果显示：立地条件和苗木类型对3年生红锥林分保存率及生长量指标均造成显著差异影响。不同处理中,保存率最高的处理为R1和R2,树高最高的处理为R1,胸径最大的处理为R1和L1,立木材积最大的处理是R1。分别分析立地条件和苗木类型对造林效果的影响可知,立地条件相同时,容器苗造林效果优势明显,但容器苗的这种优势会随着立地条件改善而减弱；立地条件的改善可促进林分各项指标的提高,但立地条件较好时,立地的差异对林分保存率影响较小。

Effects of site conditions and seedling types on afforestation result of Castanopsis hystrix |

| Abstract: | Multivariate analysis of variance and multiple comparison were used to analyse effects of site conditions and seedling types on afforestation result of Castanopsis hystrix. The results showed that the influence of site conditions and seedling types on afforestation result was extremely significant. The treatment with the highest preservation rate was R1 and R2. The treatment with the highest tree height was R1. The treatment with the largest diameter of a cross-section of a tree trunk 1.3 meters above the ground was R1 and L1. The treatment with the largest volume was R1. The effects of site conditions and seedling types on afforestation result were analyzed. The analysis showed that when the site conditions were the same, the container seedling afforestation effect was obvious. And the advantage of container seedlings would decrease with the improvement of site conditions. The improvement of site conditions was beneficial to the improvement of stand indexes. And when the site condition was good, the site difference had little effect on the stand preservation rate. |
