| 摘要: |
| 出于探索更高效的杉木丰产林培育技术的目的,在连山首次开展杉木优良无性系造林。从广东省林业科学研究院引入6个杉木无性系,营林700亩,各无性系造林面积100亩-150亩,成活率94%-96.6%；3年的树高、胸径生长量分析显示无性系及本地普通种间存在极显著的差异,各无性系优于本地普通种,无性系间存在的显著差异为筛选适合本地的杉木无性系提供依据。同时开展的杉木无性系造林培训,共培训人员达120人次。 |

| Abstract: |
| For the sake of exploring the more effective ways for high-yielding cultivation of Cunninghamia lanceolata in lianshan County, clones of Cunninghamia lanceolata were deployed. Six clones were imported from Guangdong Academy of Forestry, 47-hectare forest stand was established, with 6.67-10 hectares for each, ratio of the survival was about 94%-96.6%. ANOVA showed that highly great significance was existed among clones and original in height and diameter at breast height, clones were observed superior than the original breeds. Significant difference appeared among clones, which provided evidences to select best clones in Lianshan county. Training for the clones reforestration of Cunninghamia lanceolata was also carried out, and 120 persons were included. |
