摘要 为有效控制威廉斯B6香蕉的株高与株型,采取田间试验的方法,研究了宿根蕉苗期不同物理截茎处理对香蕉生长发育特性(株高、围茎、青叶数、叶间距)的影响。结果表明:在大田生产的情况下,香蕉截茎处理能够起到蕉株矮化的效果,同时对围茎、青叶数和叶间距的影响显著。其中,截茎2次(第1次在株高长到80 cm、第2次在蕉株抽出第1片大叶后)的处理效果最好,能够显著抑制株高、增加青叶数,同时对蕉株围茎无显著影响。 In order to control the plant height and type of banana Williams B6, the field ex- periment was designed to study the effects of different stem severing methods on the growth characteristic (plant height, stem girth, leaf number and leaf distance) of banana at seedling stage. The results showed that severing stem had the effect of dwarfing banana tree and signifi- cantly improving stem diameter, leaf number and leaf distance. Severing stem twice (the first time when the plant height reaches 80cm, the second time when the first big leaf sprouts) could obtain the best effect on inhibiting plant height and increasing green leaf number, but not obviously affect the stem girth.
