摘要：

以15年生‘石硖’结果树为试材，在顶芽萌动期喷施不同浓度的乙烯利和多效唑，观察其对龙眼花芽分化的影响，筛选出适合的龙眼预防冲梢药剂。结果发现在春季龙眼花穗顶芽刚开始萌动，芽体变软时喷施乙烯利233 mg/L+多效唑90 mg/L，或者乙烯利300 mg/L+多效唑90 mg/L对龙眼预防冲梢、促进花穗形成效果最好。

Abstract:

Different concentration of ethephon and paclobutrazol was sprayed on the 15-year-old ‘Shixie’ longan fruiting trees during the terminal bud budding dates and the adaptive reagent preventing spring inflorescence with branch leaves was selected by observing the effects of ethephon and paclobutrazol on longan flower-bud differentiation. The results showed that 233 mg/L ethephon + 90 mg/L paclobutrazol, or 300 mg/L ethephon + 90 mg/L paclobutrazol showed the best on preventing longan spring inflorescence with branch leaves and causing flower cluster forming when they were sprayed at the beginning of spring longan flower cluster terminal bud becoming germinating and softening.
