新红星苹果是我县近几年引入的栽培面积最大的短枝型品种,为探讨其整形修剪技术,确定合适的修剪量,我们于1989～1990年进行了一年生强旺枝修剪反应规律的研究。现将试验结果总结如下: 一、试材与方法试验地设在龙家圈乡西宣庄村,面积40亩,土质为轻砂壤,土层深60～80cm,有水浇条件。1987年春定植。株行距为2×4米。试验前在肥水管理相同的地块上,选其生长情况基本一致的植株为试材,并在其2年生主干上选着生角度、粗度、生长方向基本一致、长度在90cm左右、自然生长的一年生强旺枝,进行以下处理:
New Star apple is our county in recent years the introduction of cultivated area of the spur-type varieties, in order to explore its plastic pruning technology, to determine the appropriate amount of pruning, we carried out from 1989 to 1990 annual vigorous branch pruning law study . Now the test results are summarized as follows: First, the test materials and methods Experimental ground located in the Xuanzhuang Village, Longjiaquan Township, an area of 40 acres, light soil soil, soil depth 60 ~ 80cm, with water conditions. Spring 1987 planting. Line spacing of 2 × 4 meters. Before the experiment, on the same plot of fertilizer and water management, the plants with the same growth status were chosen as the test materials, and the angle, thickness and growth direction of their biennial stems were basically the same, with the length of about 90cm and natural growth Annual strong branch, the following processing:
