以长岭岗林场日本落叶松种子园大龄母树为研究对象,开展去顶及修枝试验,结果表明:去顶修枝对促进日本落叶松母树新生枝条萌发的效果显著,不同修剪强度之间萌条数量和质量差异显著,修剪强度越大新生萌条数量和质量越好;修剪后第4、5年雌雄球花数量均很少,与对照相当或少于对照,去顶修枝对促进花芽分化作用不明显。
以長嶺崗林場日本落葉鬆種子園大齡母樹為研究對象,開展去頂及脩枝試驗,結果錶明:去頂脩枝對促進日本落葉鬆母樹新生枝條萌髮的效果顯著,不同脩剪彊度之間萌條數量和質量差異顯著,脩剪彊度越大新生萌條數量和質量越好;脩剪後第4、5年雌雄毬花數量均很少,與對照相噹或少于對照,去頂脩枝對促進花芽分化作用不明顯。

This paper studied the pruning effects on old seed tree in seed orchard of Larix kaempferi in Changling Hillock Forest Farm.The results showed that the effect of pruning on new branch sprouting was significant.The quantity and quality of coppice shoot was significantly different within different treatments.The more we pruned,the more it sprouted.The number of male and female cone after the pruning treatment in the fourth and fifth year was both few and less than that of the check.In addition,pruning had little effect on promoting bud differentiation.
