柑桔为常绿果树,在广西一年四季均可发梢,特别是夏季高温多雨,陆续萌发大量夏芽。因其幼嫩,新陈代谢旺盛。形成新的生长中心,促使大量养分和水分优先运往夏芽而抽成夏梢,大大阻碍幼果的生长发育,影响产量。因此,及时抹除夏梢已成为柑桔丰产栽培的必要措施之一。现大都使用人工抹梢,费工费时不经济。 Citrus trees are evergreen fruit trees in Guangxi can be hair all year round, especially in the summer hot and rainy, one after another to sprout a large number of summer buds. Because of its tender, strong metabolism.

Therefore, the timely removal of summer shoots has become one of the necessary measures for citrus cultivation. Mostly use the manual wipe, laborious and time-consuming economy.
