摘要:

在林下间隙和斑块营造红松是促进天然次生林向阔叶红松林转变的重要经营手段。不同类型的次生林林冠下生长环境各异,对红松幼林生长与适应会产生不同的影响。本研究在小兴安岭丽林实验林场不同林型(杂木林、杨桦林和硬阔林)下开展了红松种源试验研究,结果表明:不同林型对红松源地径、树高、当年高和保存率性状具有显著影响;不同林型下红松造林效果最好为杨桦林,其次为硬阔林,最差是杂木林;铁力种源为杨桦林和杂木林林下造林用的优良种源,汪清种源为硬阔林下优良种源。

Abstract:

The afforestation of Pinus koraiensis under canopy is an important management method to promote the transformation of natural secondary forest to broad-leaved Korean pine forest. For different tree species and composition ratio, the forest afforestation environment is very different in the diverse types of natural secondary forest. However, there was no research on the improvement of P. koraiensis varieties in Korean pine afforestation under canopy of natural secondary forest. In view of problems above, the provenance test of Korean pine was performed in different types of natural secondary forests, such as mixed forests, Poplar-brich forests, and hardwood forests, in Lilin experimental forest station of Xiaoxing’an mountains. The results showed that there were significant or extremely significant differences in diameter above ground, height, 7-year high growth, one-year high growth, and conservation rate of Korean pine provenances among different types of natural secondary forests; the Poplar-brich forests exhibited the best performances of Korean pine afforestation under canopy, followed by hard broad forest hardwood forests by turn; the Tieli was the superior provenance for afforestation in Poplar-brich forests and mixed forests, while the Wangqing provenance showed the best performance in the excellent provenance in hardwood forests.

Key words: Xiaoxing’an Mountains, Lilin Experimental Forest Station, type of natural secondary forests, Pinus koraiensis, provenance test, superior provenance
