摘要

本文研究了集约化人工林中不同修剪方式和修剪条件对苹果叶片器官形态的影响。科学地证实和证明了叶片器官的变化主要取决于修剪树冠的时机和方法。经研究发现，苹果树的轮廓修剪面积比叶片面积大14%，在粉果期修剪- 11%后，在粉果期实施这一农业措施，可使苹果树的总叶面增加20%，叶片增厚8%，叶数减少17%。关键词:苹果树，修剪方法，修剪周期，机械(轮廓)修剪，叶表面积，叶片厚度。

The effect of pruning practice and term on a leaf area of apple-trees

The article is devoted to the study of morphological changes of the apple leaf apparatus in the intensive plantations depending on different methods and terms of pruning. The article scientifically substantiates and proves that changes in the leaf apparatus primarily depend on the timing and methods of pruning the crown. It was found out that the contour pruning of apple trees is 14% larger than the area of the leaf blade, and after pruning in the pink cone phase - 11%, the implementation of this agricultural measure in the pink cone phase increases the total leaf surface by 20%, thickens the leaf blade by 8% and reduces the number of leaves of apple trees by 17%. Key words: apple tree, pruning method, pruning period, mechanical (contour) pruning, leaf surface area, leaf blade thickness.
