桂花如何修剪整形

除樹勢、枝勢生長不好的應短截更新外,一般應以疏枝為主。枝條過密的植株可適當剪去內膛枝、細弱枝、病蟲枝,使之通風透光,錯落有致;長得過高、下部又缺少枝條的植株,可將主幹頂部剪去,促使下部樹幹萌發新枝;幼樹的修剪應從幼苗開始,選留一個主幹,當主幹長到預定高度時打頂,促使其萌發3~5個側枝,使之形成獨幹式樹冠。

    成株每年花謝之後可將夏、秋季生出的徒長枝全部剪去,保留健壯的春生枝條;春季萌芽前再將乾枯枝、病蟲枝、密生瘦弱枝全部剪去,使養分集中到保留的枝條上,促使其多開花,且使樹形整齊、優美。

    若植株出現上強下弱、樹形不佳現象時,可適當進行短截,促使下部萌發不定芽,長出新枝。但短截不能過多,否則易萌發徒長枝,影響開花數量。經過修剪整形後的桂花樹,應加強水肥管理,發現樹幹基部出現萌?枝時要及時除去,以免消耗養分,擾亂樹形。
