抹除原发花序利用后发花序改善妃子笑荔枝坐果研究

抹除了妃子笑荔枝原发花序，疏剪短截后发花序可缩短花序分支发育时间和主轴的长度；减少雄性花数量，提高雌雄比值，延长雌雄花的花期，增加雌雄相遇机会，提高坐果花序百分率，在初花前１．５个月左右修剪花序可提高其质量改善坐果。

Improvement of Fruit-Set in Secondary Panicles of Feizixiao Litchi by Removal of the Primary Panicles

Feizixiao Litchi, an early-mid-season variety, often forms large and long panicles Which greatly affects its productivity. The duration of the panicle development and the lengths of the main panicles axis were shortened by removing the primary panicles, thinning and short-pruning the secondary panicles, and thus the number of male flowers was reduced, while the female/male flower ratio was increased. As a result of that, the blooming duration of the female functional flowers was prolonged, and the proportion of the fruiting panicles was increased. In conclusion, it was observed that pruning panicles one and a half months prior to first flowering could improve the quality of panicles and their fruit-set in Feizixiao litchi.
