1981年8月至1982年2月,以五种砧木上的5年生红储苹果作试材,对单个骨干枝进行3种修剪处理或者不剪,结果表明,夏剪和冬剪对树体的反应相似;修剪强度和砧木间没有明显的相互作用。1982年12月,枝围与修剪强度呈负相关。与对照相比,1982年所有修剪强度均使新梢量减少而平均长度增加;仅最重修剪处理减少了新梢生长总量。1983年的开花和结果与修剪强度呈负相关。
From August 1981 to February 1982, five-year-old red apple on five kinds of rootstocks were used as materials to test three kinds of pruning or not cutting of single branch. The results showed that the effects of summer and winter cuttings on the tree The responses were similar; there was no significant interaction between the shearing strength and rootstocks. December 1982, the branch and the shear strength was negatively correlated. Compared with the control, all the pruning intensities in 1982 decreased the number of shoots and the average length increased; only the most pruning treatments reduced the total shoot growth. The flowering in 1983 and the results were negatively correlated with the shearing strength.
