摘　　要：为了给调节龙眼产期提供理论依据,探索利用龙眼末批花结果技术。以石硖龙眼为试材,于龙眼花朵零星开放时叶面喷施宇花灵4号,观测龙眼花朵(蕾)脱落率、末批花雌花比率、坐果率、成熟时间、果实单果重及可溶性固形物变化曲线等。结果表明,试验树花朵(蕾)脱落率衡定在60%～73%,花蕾脱落规律为大花蕾脱落而小花蕾(末批花)不易脱落;末批花发育成熟后雌花比率高,最高达78%;2009—2012年4年试验结果:试验树单株产量分别为42.77、42.99、58.62、66.20kg,果实成熟期比对照分别延后18、17、14、16天。利用龙眼末批花结果技术可延迟龙眼成熟期14～18天,有效调节龙眼鲜果供应期,对龙眼产量、品质无明显差异,同时,由于末批花开花期气候较稳定,坐果率高,产量稳定。In order to provide the theoretical basis for regulating longan perinatal period, the experiment was conducted to study the technology by using the end batch flower fruit setting of longan. Using the Shek Kip longan as test material, the author sprayed on the leaves that longan flower sporadically, studied the end batch flower pistillate ratio, fruit setting rate, mature period, the single fruit weight and soluble solids of variation curve and so on. The results showed that： the flower’s （bud） shedding rate of the test tree to stability was 60%-73%, the shedding of the law was big bud easy shedding of and small bud （the end batch flower） wasn’t easy shedding, the female ratio to improve after the end batch flower maturation, was up to 78% . The experimental results showed from 2009-2012, test tree plant yield were 42.77kg, 42.99kg, 58.62kg, 66.20kg, fruit maturity time needed to respectively extended 18, 17, 14, 16 days Using the end batch flower fruit setting technology of longan could made fruit maturity time needed to extended 14-18 days, effective regulation of longan fruit supply period, the longan yield and quality no difference, at the same time, the end batch flower florescence climate relatively stable, the fruit setting rate was high, stable yield.
