苹果树中庸性封顶枝,在冬剪时短截易抽生较旺的营养枝,不易形成花芽.如果缓放不剪,又易单轴生长,成花机率也很低.对这种枝,在5月中旬,顶芽萌发后,用手掰除顶芽,破坏枝条的极性生长.
In the middle of winter, when the pine tree is cut loosely, the vegetative shoots are more easily swallowed, which makes it difficult to form flower buds. If the snail is not cut and the growth is easy, the probability of flower formation is very low. In mid-May, after the top bud germinated, the top buds were removed by hand and the polar growth of the branches was destroyed.
