摘  要：
[目的]为四季蜜龙眼的示范推广提供理论依据和技术指导。[方法]以四季蜜龙眼为试材,通过田间试验研究了不同调控措施对四季蜜龙眼夏季成花坐果的影响。[结果]各处理的末次梢成花率分别为80.33%、93.96%、96.12%和70.52%,分别比对照增加了0.38、0.62、0.66和0.21倍。各处理的末次梢成花整齐率分别为67.32%、81.97%、93.33%和72.05%,分别比对照增加了0.52、0.84、1.10和0.62倍。各处理的平均单株产量分别为7.80、8.02、10.71和6.73kg/株,分别比对照增加了1.10、1.16、1.89和0.81倍。各处理的单穗果粒数分别为31.7、47.5、48.1和33.5粒/穗,分别比对照增加了2.7、18.5、19.1和4.5粒/穗。各处理的平均单穗重分别为233.04、349.26、367.18和265.53g,分别比对照增加了19.04、135.26、153.18和51.53g。[结论]在2～3月修剪和在结果母枝充分成熟时喷施乙烯利0.012%+多效唑0.008%对四季蜜龙眼夏季成花坐果的调控效果最佳。

摘  要：
[Objective] The purpose was to provide theoretical basis and technical direction for the demonstration and popularization of 'Sijimi' longan.[Method] With 'Sijimi' longan as tested material,the effects of different regulation measures on its flower formation and fruit setting in summer were studied through field experiment.[Result] The flower formation rates of last shoots in various treatments were 80.33%,93.96%,96.12% and 70.52% resp.and they were increased by 0.38,0.62,0.66 and 0.21 times resp.in comparison with that in CK.The rates of simultaneous flower formation of last shoots in various treatments were 67.32%,81.97%,93.33% and 72.05% resp.and they were increased by 0.52,0.84,1.10 and 0.62 times resp.in comparison with that in CK.The average yields per plant in various treatments were 7.80,8.02,10.71 and 6.73 kg/plant resp.and they were increased by 1.10,1.16,1.89 and 0.81 times resp.in comparison with that in CK.The fruit grains per ear in various treatments were 31.7,47.5,48.1 and 33.5 grains/ear resp.and they were increased for 2.7,18.5,19.1 and 4.5 grains/ear resp.in comparison with that in CK.The average single ear weights in various treatments were 233.04,349.26,367.18 and 265.53 g resp.and they were increased for 19.04,135.26,153.18 and 51.53 g resp.in comparison with that in CK.[Conclusion] The regulation effect of pruning in Feb.and Mar.and spraying ethephon 0.012% + paclobutrazol 0.008% in the period when the fertile mother branches were fully mature on the flower formation and fruit setting of 'Sijimi' longan in summer was best.
