摘　　要：[目的]为大面积推广切花向日葵栽培提供参考依据。[方法]从品种选择、土壤、光照、采收等方面介绍了切花向日葵品种的关键栽培技术,并对比了赤霉素(GA3)处理与对照对切花向日葵的影响。[结果]用1/1 000 GA3处理后,切花向日葵株高明显高于对照,但叶片颜色、花型、花期、花盘倾斜度、茎粗、落花性明显不如对照。[结论]用GA3处理对切花品质影响很大,在三亚地区应尽量避免使用GA3处理。[ Objective ] It provided reference for large extension of the cut sunflower cultivation. [ Method ] The key cultivation techniques of cut sunflower were introduced from species selection, soil, light, GA3 treatment and harvest. The effect of GA3 treatment and control on cut flowers sunflower was compared. [ Result] Spraying the cut sunflower seedlings with 1/1 000 gibberellin（ GA3 ）, the plant height was significantly higher than the control group. But the botany characteristics （leaf color, flower type, etc. ） were obviously not as good as the control group. [ Conclusion] GA3 treatment had a great influence on the quality of cut sunflower. It should try to avoid using GA3 treatment in Sanya.
