日本落叶松母树修剪的技术,近年来,广大林业工作者曾提出很多技术上的探讨,取得了一定的经验。而对老枝更新复壮,树冠循环更替,至今国内外尚无比较成熟的方法和经验。我们在实践中发现,日本落叶松母树采取“强度整枝”,可以刺激休眠芽萌发出新的枝条,实现老枝更新复壮,树冠循环更替,使母树永续结实。“强度整枝”方 Japan Larch tree pruning technology, in recent years, the majority of forestry workers have put forward a lot of technical discussions, and gained some experience.
