当今,我们可以看到在大部分果树生产国家,果树树形更加明显地朝着中央领导干树形方向变化,在法国,推荐中央领导干树形至今已十多年了。一些气候和土壤有利于苹果旺长的地区已经采用了这种树形。过去,按照传统的修剪方法,通常疏除那些旺盛的枝条。现在,我们必须利用旺盛的营养生长以促进花芽分化。通过对有关树体枝条构成(顶生枝类型—基生枝类型),以及各品种结果所需优良条件的研究。 Nowadays, we can see that in most fruit-producing countries, the tree shape of fruit trees changes more clearly toward the direction of the central leading cadre. In France, it is now more than ten years since the central leadership of the tree was recommended. This tree has been adopted in some areas where climate and soil are good for apples. In the past, according to the traditional pruning method, usually those sparse branches sparse. Now, we must take advantage of vigorous vegetative growth to promote flower bud differentiation. Through the branches of the tree structure (top branch type - basic branch type), as well as the results of various varieties of the desired conditions for the study.
