目前我市密植苹果园主要是80年代末90年代初栽植的,由于栽植密度过大和修剪技术不得当,造成树冠郁闭,通风透光条件差,果实着色不良,品质下降。部分果园还存在着外强内弱,上强下弱等弊病,已成为生产中必须解决的重大问题。为此,我们根据多年的生产实践经验,总结出当地密植园苹果树主枝、枝组的理想分布及与中心干的合理比例,提出了幼树、中庸树及老化树的合理修剪方法,供广大果农在优质、高档苹果生产中参考。 At present, the densely populated apple orchard in our city is mainly planted in the late 1980s and early 1990s. Due to excessive planting density and improper pruning techniques, the crown canopy is closed, the ventilation and light conditions are poor, the coloring of the fruit is poor, and the quality is deteriorated. Some orchards still exist outside the weak strong, weakness and other ills, has become a major issue must be solved in production. Therefore, based on many years of production experience, we summed up the ideal distribution of the main branches and branches of the apple tree in the local dense plantation and the reasonable proportion of them to the center, and put forward the reasonable pruning methods of the young tree, the middle-aged tree and the aged tree. The majority of farmers in the high-quality, high-grade apple production reference.
