自1960年开始,黑山县引入栽培苹果梨。现在已发展到18万株,占梨树总数的60％,年产量占各种水果总产的70％以上。近年来,我们对苹果梨树的修剪方法和修剪反应进行了试验和调查,现将我们的一点体会总结如下:1 幼树的修剪。苹果梨树定植以后,生长势较强,一年生枝平均达1米以上,分枝少,开始以长、中果枝结果为主,1米长一年生果枝顶部也能形成良好的花芽。幼树修剪除骨干枝短截外,其它枝条多缓放,少疏或不疏枝。夏季采取拉枝的方法加大主、侧枝及辅养枝角度,使幼树尽快提早结果。
Since 1960, Montenegro introduced cultivated apple pears. Now it has grown to 180,000, accounting for 60% of the total number of pear trees and annual output accounting for more than 70% of the total fruit output. In recent years, we have carried out experiments and surveys on pruning and pruning of apple pear trees. We will summarize our experience as follows: 1 Pruning of saplings. Apple pear after planting, strong growth potential, an annual average of 1 m above the branches, branches less, beginning with the long, the results of the main fruiting branches, 1-meter-long perennial fruiting branches can form a good flower buds. In addition to pruning young tree stump cut short, the other branches more slow release, less sparse or not thinning. Pull the summer to take the method to increase the main, collateral and secondary branches angle, so that young trees early results.
