对于营养生长旺盛的柑桔幼年结果树来说,夏梢常与幼果争夺养分而引起严重落果。从六十年代初开始,潮汕柑农就把及时摘除夏芽,严格控制夏梢生长作为提高单产的一项重要措施。但对于营养生长较差,生殖生长较强,开花结果较多的幼年结果树,特别是在水分缺乏,易发生秋旱的丘陵山地条件下,充分保留和利用夏梢,在生产上具有重要作用。我们从1977—1979年进行了不同树势、不同放 For vegetative growth of citrus juvenile fruit tree, summer tip often compete with the young fruit nutrients and cause serious drop. From the beginning of the 1960s, Chaoshan farmers put prompt removal of summer buds, strict control of summer shoot growth as an important measure to improve yields. However, juvenile fruit trees with poor vegetative growth, strong reproductive growth and more flowering results, especially in the hilly and mountainous regions where water deficit and drought are prone to fall, have an important role in the conservation and utilization of summer shoots . From 1977 to 1979, we carried out different tree stances and placed them differently
