| 摘 要： | 为了明确不同修枝方式对促进新生枝条生长及雌花量影响,我们对华北落叶松种子园的9个家系的母树进行不同修剪方式的树体管理试验。结果表明,疏剪、短剪及中剪形式的的侧枝修剪对新生枝条生长具有促进作用,且疏剪可促进结实。

| Abstract: | In order to make sure the effects of different branching methods on the growth of newborn branches and the number of female flowers,we tried out different pruning experiments to seed trees of nine families in the seed orchard of Huabei larch.The result showed that some pruning methods of lateral branch such as thinning,short pruning and moderate pruning promoted the growth of newborn branches and thinning improved seed setting. |
