摘　　要：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 ethephon 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.
