摘　　要：‘糯米糍’和‘桂味’荔枝幼树不挂果现象相当普遍。采用螺旋环剥能显著促进成花、改善花质、减少落果、增加产量,改善品质。糯米糍、桂味幼树在生理落果期间出现旺盛的根梢生长峰,但其成年树和坐果比较正常的怀枝幼树都没有出现这种旺盛生长,表明了品种和树龄特性的差异。螺旋环剥明显减少生理落果期间的根与梢的生长量,使果实在与根、梢之间的库力竞争中获得优势,因而有利于坐果和果实生长。Trunk spiral girdling done in early December improved flower formation, fruitsetting, crop yield and quality in Nuomici and Guiwei litchi young trees, which were tend to shy- or even non-bearing. Spiral and closed girdling both showed pronounced reducing effect on root and shoot growth during fruit development and the period of physiological drop, fruit drop, especially preharvest drop, was distinctly reduced by girdling. Adult trees of cvs. Nuomici showed no vigorous root and shoot growth as seen in young trees of the same cultivar during the physiological fruit drop period. Young trees of cv. Huaizhi which tend to fruit normally showed similar patterns of root and shoot growth as seen in adult trees of cv. Nuomici. These pertain to varietal and age-related characteristics. The difference of spiral and closed girdling in healing pattern makes the former technically easier to master in practice and yield more stable results. Further investigations in the long-term effect and anatomical and physiological features of spiral girdling, however, are desirable.
