摘　　要：采用不同方式对妃子笑荔枝花穗进行处理,比较不同处理对妃子笑荔枝开花量、开花动态、坐果率及产量的影响。结果表明,人工疏花+药物疏蕾能显著减少花量,延缓雌花开放速度,减少翻花,提高雌花开放比例及增加坐果量;人工疏花可有效减少总花量,但翻花严重,坐果率较低;药物疏花受药剂浓度、施用时间及天气影响较大,效果不稳定,坐果率低。The effects of different treatments of flower panicles on flowering dynamic,fruit setting rate and fruit yield of Feizixiao litchi were investigated.The results showed that the panicle pruning ＋ chemical bud thinning reduced the total flowers,delayed the female bloom,and raised the rate of female and percentage of setting fruit significantly.The panicle pruning effectively reduced the total flowers,but dynamic of the female bloom went against good fruit set.The effects of chemical flower thinning,influenced by pharmaceutical concentration,application time and the weather,were not stable.
