苹果树每年都要通过冬季修剪,剪掉一部分枝芽量。被剪掉的枝芽量称为修剪量。根据修剪量的大小,可分为轻剪、中剪和重剪。过去修剪量的轻重,多用重量法和剪锯口法来表示,这两种方法的剪掉量都无法与存留量进行比较,也缺乏具体的轻重标准。通过几年来的生产实践,我们认为,修剪量应以剪掉顶芽数的多少来表示较为适宜。它既能表示出修剪量轻重的程度,又能进行剪掉量与树上存留量比较。
Every year, the apple tree is pruned through the winter and some of the branch buds are cut off. Cut off the amount of branch buds called the amount of pruning. According to the size of the pruning, can be divided into light cut, medium cut and heavy cut. In the past, the amount of pruning was more than that of the weight of the pruning method. The gravidity and shearing method were used to indicate the amount of pruning. Both methods were unable to compare the amount of pruning with the amount of storage and lack specific criteria for gravitation. Through several years of production practice, we believe that the amount of pruning should be cut off the number of buds to represent more appropriate. It can not only show the degree of pruning, but also the amount of pruning compared with the amount of tree reserves.
