红提葡萄冬季修剪效应观察

为研究红提在浙南山区避雨栽培条件下的生长结果特点和修剪效应,从短梢、中梢和长梢三种修剪试验比较,分析结果母枝不同的剪口粗度和芽位对结果性能的影响,并分析不同结果母枝(更新枝、当年结果枝)在不同选留情况下的差异性表现。通过研究,认为浙南山区避雨栽培下红提冬剪时结果母枝剪口粗度控制在0.8~1.2 cm为宜,且应以6~8芽中梢修剪为主,短、长梢修剪视树势、枝条老熟程度、结果母枝粗度和空间等情况结合使用,要特别重视更新枝的培育与选用。

The Red Grape Winter Pruning Effect Observation

In order to investigate growth characteristics and pruning effects of red grape under rain shelter cultivation condition in South Zhejiang mountain area, through comparison of three pruning experiments of short shoot, medium-shoot and long shoot, this study analyzed the effects of different cutting width(diameter) and bud position on fruit bearing in fruiting mother branches, and the difference in fruit bearing performance under different selection condition between the regenerated branch and the same year fruit bearing branch of different fruiting mother branches. The study found that during the winter pruning for the red grape under rain shelter cultivation condition in South Zhejiang mountain area, the cutting width(diameter) off ruiting mother branches should be 0.8-1.2 cm, the winter pruning should be practised mainly in the medium shoot with 6-8 buds, and the pruning of short shoot and long shoot should depend on tree growth vigor, the age of branch, the fruiting mother branch diameter and space.And much attention should be paid to the cultivation and selection of the regenerated branch.
