| 摘要: |
| 本研究通过对湿加松采穗圃母株修剪促萌试验，结果表明营建湿加松采穗圃，母株最好的修剪方式是：截顶，主茎留高约10cm，从基部剪除生长细弱且过密的侧枝，对比较粗壮的侧枝采取截顶，侧枝剪口与主茎的剪口保持在同一水平面，控制分枝级数到3~4级，形成主茎短，侧枝长的平台状植株。以此种方式修剪的母株保存率高且萌穗数量多，保存率达到96.7％，平均每株产萌穗95.8条。 |

| Abstract: |
| By the trials of the added sprouts on Slash Pine× Caribbean Pine F2 hybirds seed seedlings, the effect indicated the most elite shear method in the cutting orchard is to cut the tip and keep the 10cm height of seed production stand, to shear fragile side-twigs, cut the tip of the thick branches to reach the same level height between main stem and branches, and to control the 3~4 class ramifications to form a flat roof seedling which the main stem is short and the branches is long. The survival percentage of seed production stand are to reach 96.7% and average quantities of added sprouts on one tree are 95.8. |
