摘要
常山胡柚每年抽发春梢、夏梢和秋梢３种枝梢，以春梢为主。春梢是主要结果母枝，成年树占９６．９０％～１００．００％，初投产树占９６．８９％～９９．１６％。枝粗大于０．３０ｃｍ的春梢结果母枝较为理想，但枝粗大于０．４０ｃｍ的春梢不易抽生结果枝。常山胡柚的结果枝分为有叶顶花枝、有叶花序枝、无叶花序枝和无叶单花枝４种，以有叶顶花枝座果率最高，其次是无叶单花枝，有叶花序枝与无叶花序枝座果率收低。常山胡柚内膛挂果能力较强，表现出很好的丰产、稳产性能。
There are 3 kinds of shoots-spring cycle shoot, summer shootand autumn shoot-sprouting yearly on the Citrus changshan-hugou, with springcycle shoot being dorminant,Spring cycle shoot is also a main fruit bearingmother shoot, which accounts for 90.90%～100.00%in adult trees,96.89%～99.16%in trees that begin fruiting. As a desirable fruit bearing shoot,spring cycle shoots should have a diameter of over 0.30 cm, But it’s not easyfor spring cycle shoot with a thickness of over 0.40 cm to spring fruitbearing shoots. As for fruiting shoots of Citrus changshanhugou,there areleafed top flowering shoot ,inflorescence shoots with or without leaf andsingle flowering shoot without leaf,with lst one having a highest fruit setpercentage,followed by single flowering shoot without leaf, while the fruitset percentage for inflorescence shoots with or without leaf is lower. Inaddition ,the central part of the Citrus changshan-hugou tree has a strongability to bear fruit ,which is responsible for a stable bumper harvest offruit.
