在妃子笑荔枝将要进入花芽分化期时实施螺旋环剥，观测其各生育期及产量构成要素。结果表明螺旋环剥在不良天气条件下的增产效果明显．其原因是：在秋、冬季气温偏高的天气条件下，螺旋环剥能抑制冬梢抽发，促进花芽分化，有利开花结果；螺旋环剥能推迟花期，有利于避过花期低温连阴雨天气的不良影响；春季气温偏高的天气条件下，螺旋环剥能抑制“冲梢”，利于花穗发育。

When the Litchi Chinese Sonn.cv. Feizixiao is going to enter the flower bud differentiation period , implements the spiral girdling, observes its growth periods and the yields and its components. The results showed that the effec of high yield is obvious after implements spiral girdling techniques under the bad aweather conditions, the reasons are as follow：（ 1 ） when the fall and the winter temperature is exceptionally, the spiral girdleing can inhibit the growing of the winter shoots and promote the flower bud differentiation, beneficial to the blossom and the bear fruit; （2） the spiral girdleing can postpone the flowering season, evading the adverse effec for the low temperature and continuous rainning; （3） when the Spring temperature is exceptionally high, the spiral girdling can inhibit blossom clusters form leaf lets and promote the flower formation.
