在较好的栽培管理条件下,苹果幼树生长旺盛,长出的1—2年生辅养枝大多数具有春梢和秋梢。过去,我们对这些辅养枝修剪不当,造成了适龄不结果现象。近年来,我们根据这些辅养枝的春梢和秋梢交界处有盲节,而在盲节的上、下部各有几个鳞片数和叶原基数都较少的芽,这些芽翌年萌发迟,长 Under better cultivation and management conditions, young apple trees grow vigorously and most of the 1-2 years old growing branchlets have spring shoots and autumn shoots. In the past, we improperly pruned these secondary support priests, resulting in an age-ineffective result. In recent years, we have blind spots at the junctions of the spring shoots and autumn shoots of these branches, while those at the upper and lower parts of the blind spot have a few buds with fewer scales and leaf primordia. These buds germinate the following year ,long
