柑桔幼树一年要抽发3～4次枝梢,而夏梢是扩大树冠的主要枝梢。由于幼龄结果树的营养生长比较旺盛,枝梢抽发能力较强,在5～7月夏梢生长期间,常常因梢果互相争夺肥水而引起严重落果。在栽培上常对夏梢进行适当的抹除或者摘心来减少落果,以提高幼龄结果树的产量,达到幼龄树早产高产的目的。一、夏梢在柑桔幼龄结果树中的作用 Citrus young trees to pump 3-4 shoots a year, while the summer tip is the main branch to expand the crown. As a result of juvenile tree nutrition growth is relatively strong, shoots strong ability to shoot, during the summer of May to July growth period, often competing each other because of the fruit and water to cause serious fruit drop. In the cultivation of the summer tip often appropriate erase or topping to reduce the drop fruit, in order to improve the yield of young results tree, young trees to achieve the purpose of premature delivery of high yield. First, the summer shoots in citrus young results tree role
