一年生枝因其着生部位不同又分为延长枝和分枝。各级枝先端生长的一年生枝叫延长枝,也叫顶梢。在延长枝下面侧生的一年生枝叫分枝,也叫侧梢。延长枝是继续延长各级主侧枝,扩大树冠,引导伸长方向的。所以在幼龄时期以适当长留为宜,一般可在中部或中上部充实饱满芽处短截,长度在27～40cm,长者50cm。土质肥沃,生长期长的地区可适当长留。长留有
Annual branches due to their different parts of life is divided into extended branches and branches. Annual branches of all branches of the growth of branches called the extension of branches, also known as the top shoot. In extending the lateral branches below the annual branches called branches, also called lateral shoots. To extend the branch is to continue to extend the main branches at all levels, to expand the crown, to guide the elongation direction. Therefore, in young age appropriate long stay is appropriate, usually in the middle or upper part of full bud bud, length of 27 ~ 40cm, the elderly 50cm. Soil fertile, long growing areas may be appropriate long stay. Long stay
