锦绣黄桃优变株系不同类型果枝结果性能比较分析

Comparative Analysis on Fructifying Capabilities of Different-type Branches of Excellent Mutant Lines derived from Yellow Peach cv. ‘Jinxiu'

为使‘锦绣’及其系列优变株系生产上采取更具针对性强的栽培技术措施提供理论依据,以‘晚绣’为对象,对其各类型果枝结果性能进行系统调查与比较分析,结果为:长度类型上以中、长果枝结果为主的特性明显,尤以中果枝结果性能最好;粗度类型上以中果枝及粗度趋近中果枝粗度的长果枝、短果枝结果性能好;伸向类型上以水平、斜上伸向类型果枝结果性能强。生产上应通过加强肥水调控与合理修剪等措施,增加粗壮中果枝及粗度、长度近于中果枝的长果枝、短果枝数量,以利于提高产量、增进果实品质。

To provide the theoretical basis for the key targeted cuhivation techniques of yellow peach cv. ＇Jinxiu＇ and its excellent mutant lines, ＇Wanxiu＇ was used as the research object to investigate and analyze fructifying capabilities of different-type branches. The results showed that medium and long-type branches were the main bearing branches, especially the fructifying capability of medium-bearing branches were best. Among different thickness types, the branches with thickness near medium-bearing branches had the best fructifying capability. And the branch types with horizontal or oblique angel also had the best fructifying capability. Therefore, the increasing number of branches with thickness near medium-bearing branches could enhance the yield and fruit quality by strengthening fertilizer and water management and reasonable pruning.
