摘　　要：以百玉1号为材料,分别在玉米拔节期(10片可见叶)喷施缩节短、恐高、黄金玉配3种化控药物,并在大喇叭口期、抽雄期、灌浆期、成熟期调查玉米株高、单株叶面积、茎粗、各节间长度、产量等相关性状。结果表明:在大喇叭口期、抽雄期、灌浆期喷施化控药物后,玉米株高分别降低26.33～42.33、17.33～28.33、16.00～19.00 cm;在大喇叭口期、抽雄期、灌浆期和成熟期喷施化控药物后,单株叶面积分别减少456.68～594.18、80.70～279.48、628.15～980.92、257.79～880.42 cm2;3种化控药物均可使茎秆增粗,增粗幅度为0.06～0.23 cm,不同化控药物之间存在差异显著;化控药物对玉米产量有较明显影响,可使玉米增产8.30%～11.11%,其中缩节短对玉米的增产效果最好,比清水对照增产11.11%。The experiment takeing maize variety BaiYu No：l as material and spraying Suojieduan, Konggao,Huangjinyupei etc three kinds chemical control drugs on leaves at maize jointing stage, and investigating the maize plant height, stem diameter, a plant leaf area, yield etc related traits at the full-grown stage, anthesis stage, filling stage and maturity stage. The results showed that after spraying chemical control drugs, the maize plant height reducing range between 26.33 -42.33 cm in the big bugle stage, the maize plant height reducing range between 17.33-28.33 cm in the anthesis stage, the maize plant height reducing range between 16.00-19.00 cm in the filling stage. In the big bugle stage, anthesis stage, filling stage and autumn stage the leaf area per plant was significantly reduced, reducing range between 456.68-594.18, 80.70-279.48, 628.15-980.92, 257.79-880.42 cm2, respectively. After sprayed Suojieduan the corn plant stem thicker 0.23 cm than CK, and sprayed chemical control drugs the stem diameter increase range between 0.06-0.23 cm, stem diameter changes was significantly. Spraying chemical control drugs on corn yield was significant, the increase range between 8.30% -11.11%, the Suojieduan increased yield 11.11%, it was the highest.
