为高效、安全地调控龙眼冲梢，在龙眼花芽形态分化开始期(露红点期)和花穗主轴长6~9 cm的花穗展叶期，施用生长调节剂，比较了不同方法调控龙眼冲梢的效果.结果发现龙眼花芽形态分化开始期树冠喷施200 mg/kg乙烯利＋150 mg/kg多效唑混合液和土施多效唑每株4 g处理控冲梢效果都显著高于对照，冲梢率分别是10．5％和7．6％，在花穗小叶处于展叶期虹吸输300 mg/kg乙烯利防控龙眼冲梢有效且安全.

The effects of shoot growth controlled by growth regulator spraying on flower bud differentiation (red point appearing)and flower inflorescence spindle elongation 6-9 cm and leaf expansion was studied in order to regulate shoot growth safely and efficiently.The results indicated that foliar-spraying 200 mg/L ethe-phon and 150 mg/L paclobutrazol,or soil application 4 grams per plant paclobutrazol had the best effect on preventing shooting inflorescence from branch leaves.Shooting of inflorescence was singificantly controlled by 300 mg/L ethephon with siphon infusion.
