目前,大部分用普通红元帅4×5米株行行距定值的果园,都存在着结果晚、产量低的问题。在栽培管理上如何应用技术,使苹果幼树结果早、丰产稳产。主要技术途径有以下方面: ——培养丰产树形骨架。采用疏散分层形树形,主枝5～6个,分两层,第一层3个,第二层2～3个,层间距80～100厘米。侧枝15个,第一层主枝各配备3个侧枝,第二层主枝各配备2个侧枝。树高4.5米开始落头。修剪前三年重点配备骨干枝,整形促冠,骨干枝头
At present, most of the orchards with ordinary Red Marshal 4 × 5 meters of line spacing from the value of the result, there is the problem of late results, low yields. How to apply the technology in cultivation and management so that the results of early young apple trees, high and stable yield. The main technical approach has the following aspects: - Cultivation of high yield tree-shaped skeleton. The use of evacuation layered tree shape, the main branch of 5 to 6, divided into two layers, the first layer 3, the second layer 2 to 3, the layer spacing of 80 to 100 cm. 15 branches, the first branch with 3 main branches, the second branch with 2 main branches. 4.5 meters high tree began to fall. Three years before the pruning key equipped with backbone, plastic crown, backbone branch
