优美的整形

梅花、碧桃、橡皮树等乔木类花卉都具有较强的发枝能力，如果任其自然生长，将会造成树形的紊乱。因此在扦插或嫁接成活后，在特定时间需要进行整形，可以使花卉长的更好，也更具欣赏价值。

整形时，首先要培养一段粗壮的主干，将30～50厘米以下萌发出来的侧枝全部剪掉，2年以后对主干的先端进行截顶，防止它们长成一根独杆，截顶的高度不要超过80厘米。截顶后，根系吸收上来的营养物质将集中在剪口附近，于是刺激腋芽萌发而抽生侧枝。这时应选留3个分布均匀并向不同方向生长的侧枝做侧主枝（一级侧枝），将多余的侧枝从基部疏掉。侧主枝生长1年后，当它们长到80厘米左右时进行短截，留枝的长度以60厘米左右为好，让它们萌发出二级侧枝，同样保留3根并将多余的侧枝疏掉，这样就形成了“三权九顶”的基本树形。以后再对这9根二级侧枝进行短截，让它们继续萌发小侧枝来形成丰满的树冠，同时保留树膛内的小枝来增加着花部位。
