我省为苹果新发展区,有苹果树2500余万株,其中结果树800万株左右,年产约2亿斤。但部分果产区,由于栽培管理粗放,苹果产量低而不稳。加之盛果期树以大小年现象严重的国光苹果为主,其产量约占苹果总产量的50％,因此更影响了果品的产量、质量和果树的寿命。据此,克服苹果大小年现象,实现高产稳产,是生产上急待解决的实际问题。现就改进和提高苹果整形修剪技术方面,谈一点个人的体会,供参考。
The province is a new development area for apple, with more than 2,500 apple trees, of which about 8 million trees are produced, with an annual output of about 2 billion kilos. However, part of the fruit producing areas, due to extensive cultivation and management, low and unstable apple production. In addition, the fruit-bearing stage is dominated by Guoguang Apple, which has serious size and year-round phenomena. Its output accounts for about 50% of the total output of the apple, thus affecting the fruit yield, quality and fruit tree life. Accordingly, to overcome the size of the apple year-round phenomenon, to achieve high and stable yield, the production is an urgent problem to be solved. Now to improve and enhance Apple plastic pruning technology, talk about personal experience for reference.
