梨树密植是当前果树栽培的一项重大改革。实行密植,必须有一套相应的栽培管理技术,尤其是整形修剪技术更需要与栽培形式相适应,才能获得高产。目前各地梨树的栽培密度与栽植形式很多,整形修剪方式也各异。但总的原则都要做到:“紧缩骨架,轻剪长放,引缚控长,以果压冠”,使树冠紧凑矮小,充分利用光能。现仅就目前生产中试用的株行距为2×5米和两行一带的株、行、带距为3×2×6米的小冠单层半圆形的栽植形式,和7×7米或
Close planting pear tree is a major reform of the current fruit tree cultivation. The implementation of close planting, there must be a set of appropriate cultivation and management techniques, in particular plastic trimming techniques need to adapt to the form of cultivation in order to obtain high yield. Currently pear cultivation density and planting a lot of form trimming methods are also different. However, the general principle must be: “tightening the skeleton, cutting light and long, dragging the captains, and pressing the crown” to make the crown compact and make full use of light energy. Now only the current trial production line spacing of 2 × 5 m and two rows of strains, lines, with a distance of 3 × 2 × 6 m small crown semi-circular planting form, and 7 × 7 m or
