摘  要:
以河北省木兰围场国有林场管理局新丰林场和山湾子林场的蒙古栎、山丁子、油松作为研究对象,采用不同修剪强度(轻度修剪、中度修剪、重度修剪等)对胸径基本一致或者树龄基本一致的几组油松、山丁子、蒙古栎进行修剪,以树木的新梢生长量作为测定指标,对每组油松、山丁子、蒙古栎进行测定、记录、对比、观察,结果表明:一般情况下修剪强度越大,新梢生长量越大,重度修剪的油松新梢生长量比轻度修剪提高58.5%,蒙古栎提高73.2%,山丁子提高67.7%。

摘  要:
A systematic research on the pruning technology of Pinus tabulaeformis,Malus baccata and Quercus mongolica seedlings at Xinfeng Forest Station and Shanwanzi Forest Station of Mulanweichang National Forest Farm Administration in Hebei Province was conducted.Through the adoption of different pruning intensity(light pruning,moderate pruning,and heavy pruning),three groups of Pinus tabulaeformis,Malus baccata and Quercus mongolica with identical DBH and age were pruned.With new shoots growth of trees as an index,the trees were measured,recorded and surveyed in contrast.The results showed that the greater pruning intensity would lead to the higher increment and the faster promotion of the tree growth,with upto 58.5% growth of heavily pruned new shoots of Pinus tabulaeformis over the lightly pruned,73.2%increment of Quercus mongolica and 67.7%increment of Malus baccata.
