摘要
在对碧桃生物学特性进行观察的基础上,开展整形修剪试验研究。结果表明:整形修剪对碧桃树冠内枝条的组成、枝条的着花量、花期都有影响,通过抑上缓下、疏外缓内、缩前截后的综合修剪方法,能够改变树冠枝类比例,明显减少旺花枝的量,增加有效花枝的量,使花期延长;通过疏除上部旺枝和密挤大枝,回缩外围枝可以调整树冠的结构,使碧桃光秃带减少,观赏价值提高。
On the base of the study of Prunus persica’ s biological characteristics ,this research developed the pruning experiment ,it showed that pruning influenced the composition of branches ,amount of flowers,flowing period.Through the method of slowing down the inside and downside ,inhibiting the upside and pruning outside ,it could change the proportion of the tree branches ,reduce the a-mount of flourishing flowers and prolonged florescence.Through adjusting the structure of crown ,it could reduce the baldness of flow-ering peach ,and improve the ornamental value.
