处于营养生长和结果年龄的温州蜜柑,每年均抽发大量的夏梢。这种梢除少数用于扩大树冠或补充树冠空缺外,一般应于清除。夏梢生长量大而不充实,消耗大量养份,牵制正常枝序的生长发育,甚至导致严重的后期落果。为了控制夏梢的生长,促使柑桔早果丰产,多年来,人们采取摘心、抹梢、短截、疏剪等措施,取得了一定效果。但这些措施实施起来较为麻烦、费工,往往由于反复抹梢的结果,在枝端节位处形成丛生扫帚枝簇。为了寻求一种简便而有效的控制夏梢生长的办法,笔者于1981—1982年采取“断根控夏梢,夏剪促秋梢”的技术措施取得了较好的增产效果,现将初步结果报告如下。 Satsuma in vegetative growth and the results of age, each pumping a large number of summer shoots. This type of shoot, except for the few used to expand the crown or fill the canopy, should generally be cleared. Summer shoot growth is large and not full, consume a lot of nutrients, the growth of the normal branch of the growth and development, and even lead to serious post-harvest fruit. In order to control the growth of summer shoots and promote the early fruiting of citrus fruits, people have taken some measures such as topping, scalping, stubbing and pruning for many years and achieved some results. However, these measures are troublesome to implement and laborious work often results in the formation of clusters of broom brooms at the branches and knuckles due to repeated brushing. In order to seek a simple and effective way to control the growth of summer shoots, the author achieved good yield-increasing effect by adopting the technical measures of “cutting root control summer shoots and summer cutting promoting autumn shoots” from 1981 to 1982, and now the preliminary results report as follows.
