果树的夏季修剪并非新方法,一百多年前就有人在夏季对新梢进行3～4次的摘心,处理后,生长量减少,促使树形改变。不过,过去那种过激的夏季修剪对现在果树栽培来说会怎样呢?我们的要求在于高产优质,而修剪能够增加收益,这就是我们把修剪放在优先地位的原故。未经修剪的果树,特别是幼树,生长迅速并很快扩大树冠体积。 Summer pruning of fruit trees is not a new method. Someone hundred to seventy years ago, people pinpointed the shoots 3 to 4 times in summer. After treatment, the amount of growth was reduced and the tree shape was changed. However, what kind of extrinsic summer pruning would be the current fruit tree cultivation? Our demand is to produce high quality, and pruning to increase revenue, which is why we put pruning in the first place. Uncut pruned fruit trees, especially saplings, grow rapidly and rapidly expand the crown volume.
