| 摘 要： | 研究了摘叶、前期不同时期喷施多效唑和后期低浓度多效唑灌根三种途径控制一品红千禧品种的株型，结果表明：摘2～3叶能明显抑制其顶端优势，降低顶芽株高2．5-2．8cm，在打顶前和打顶后7d进行40mg／L的多效唑喷施，植株矮化效果最好，降低高度13．8cm，后期3张苞叶转色时用1mg／L的多效唑灌根，能降低株高2．9cm，而对苞叶的大小基本无影响，提高了植株的观赏性。

| Abstract: | Experiment was carried out on effect of priming leaf,early stage foliar spraying paclobutrazol and later stage root-drenching paclobutrazol to control ideotype of Euphorbia pulcherrima.The result showed that priming 2 or 3 leaves could evidently inhibit apical dominance,and early stage two times foliar spraying 40mg/L paclobutrazol(7 days before and after top removal) and later stage root-drenching 1mg/l paclobutrazol(3 bracteal leaf color transferring) had obvious dwarfing effect thus making increase its value. |
