针对桃树在南方温暖湿润气候环境下顶端优势明显、营养生长过旺的生长发育特点,研究并推出了有别干Y型整形的桃两主枝开心形,该树形通过在适度开张的2个主枝上配置侧枝和结果枝组来调和树势,促进成花坐果。本文对桃两主枝开心形树体结构、整形方法、树形特点进行了总结分析,并阐明了桃两主枝开心形在浙闽丘陵山地桃区的应用前景。

Referring to peach characteristics growth and development with obvious apical dominance, excessive vegetative growth under warm and humid climate condition in thesouth, two open-center shape, different from Y type pruning, was studied and recommended. The type of pruning tries to balance tree vigor and promote flowering and fruiting by configurating lateral branch and bearing branch group on two open moderately main braches. This article summarized the tree structure, pruning method and pruning characteristics of peach two open-center shape, and illuminated the application prospect of peach two open-center shape in hilly mountains of Zhejiang and Fujian.
