富士系苹果已成为我省的主栽品种之一。但在栽培管理过程中尤其在整形修剪中存在着一些值得重视和亟待解决的问题。 1、树形不当一些中等栽植密度的红富士园,仍沿用稀植大冠树形和修剪方法。例如,行株距为5米×4米、4米×3米,还采用疏层形,栽后4～5年,株行间便交接,时间越长问题越大。有些栽后5～8年生树,整成疏层形,除留出主、侧枝外,还配置了副侧枝,形成骨干校多、级次高、健壮校组少的后果。对这样的树,应改为小冠疏层形或改良纺锤形,减少侧枝,去除副侧枝,降低级次,加大主、侧枝角度,培养相应的健壮枝组。
Fuji apple has become one of the main cultivars in our province. However, there are some problems worth paying attention to and urgent problems in crop cultivation and management, especially in plastic pruning. 1, improper tree shape Some medium planting density of Red Fuji Garden, still use the crown planting and pruning methods. For example, the line spacing of 5 m × 4 m, 4 m × 3 m, also used sparse layer shape, transplanted 4 to 5 years, the line will be transferred between the line, the longer the problem. Some planted trees after 5 to 8 years, sparse into the whole form, in addition to stay out of the main, collateral, but also the configuration of the collateral, the backbone of the formation of more school, high grade, less robust school consequences. For such a tree, it should be replaced by sparse layer crown or improved spindle shape, reduce the side branches, remove the secondary side branches, reduce the level, increase the main, collateral angle, training the corresponding robust branch group.
