目前结果的密植苹果园,大多存在枝多冠密,通风透光不良,结果部位外移,产量低,品质差,管理不便等现象。下面根据各种密植苹果园存在的实际问题,提出解决措施,供参考。 一、乔砧普通型密植园 栽植密度为2～2.5×3～3.5m不等,多采用老树形,老方法修剪,造成主枝粗大,树姿直立,株间交叉,通风透光差,喷药及其它管理不便,成花少,产量低。由于主枝已粗大,开角很难,即使强行拉开,主枝间相互交叉,仍然无效。 解决措施:1.疏、缩法。将直主角度小的基层主枝回缩到外围伸展适宜的水平枝上(背后枝换头)。二、三层以上的主枝,细小、水平的留
The current results of densely populated apple orchard, most of the existence of branches crowns dense, poor ventilation and ventilation, the results of site relocation, low yield, poor quality, management inconvenience and so on. The following based on the actual problems of all kinds of densely populated apple orchard, put forward solutions for reference. First, the average density of Joe anvil planted planting density ranging from 2 to 2.5 × 3 ~ 3.5m, and more use of old trees, the old method of pruning, resulting in the main branch thick, tree-shaped erect, cross between strains, poor ventilation and light, Spraying and other management inconvenience, less flowers, low output. As the main branch has been thick, open angle is difficult, even if forcibly opened, the main branch of each other, is still invalid. Solution: 1 sparse, shrinking method. Will be the main direct angle of the grassroots main branches retracted to the periphery of the appropriate level of extension of the branches (behind the stick for the head). Second, three or more of the main branch, small, horizontal stay
