普洛马林和刻芽处理对2年生樱桃幼树分枝特性的影响

Influence of Promalin and Bud-Notching Treatment on Branching Character of 2-Year-Old Cherry Trees

以2年生樱桃幼树(9-19/马哈利)为试材,研究了普洛马林和刻芽等处理对樱桃幼树分枝特性的影响。结果表明,与对照处理比较,采取涂普洛马林、刻芽+涂普洛马林和刻芽三种措施均能显著促进樱桃幼树萌芽抽枝。其中,刻芽+涂药处理相对于仅刻芽和涂药处理,更有利于促进中心领导干萌生较多的侧生枝,不仅萌发的新梢数量多(28条),单株叶片数量也最多(818个),且分枝高度合理(60～140 cm),各方位的分枝数目接近1∶1∶1∶1,树体结构匀称、合理。

The 2 - year - old cherry trees （9 - 19/Mahaleb） were used to study the influence of Proma- lin and bud - notching treatment on branching characters. The results showed that all the treatments of Proma- lin, Promalin ＋ bud - notching and bud - notching promoted the cherry sapling sprout significantly, compared with the control. Among them, the treatment of Promalin ＋ bud - notching was more beneficial to promoting more lateral branches, showing as the most number of shoots （28） and leaves per plant （818）, reasonable branch height （60 ~ 140 era） and branch distribution （the number of branches in each direction close to 1： 1 ： 1 ： 1 ） , so the tree body structure was symmetry and reasonable.
