摘　　要：以玉米品种洛玉4号为材料,在玉米拔节期(11片可见叶)喷施缩节短、恐高、黄金玉配和玉黄金4种化控药物,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、产量等相关性状。结果表明,喷施化控药物后,玉米株高降低13.5～30.3 cm;在大喇叭口期和灌浆期单株叶面积减小273.62～2 813.36 cm2,在抽雄期和成熟期单株叶面积各处理间差异不显著;4种化控药物均使茎秆增粗0.06～0.21 cm,与对照相比差异显著或极显著;对株高影响达到极显著水平,喷施化控药物后对玉米产量的影响极显著,增产5.13%～12.94%,玉黄金的增产幅度最大,达到12.94%,建议在生产上大力推广应用。The effects of spraying 4 chemical control drugs（Konggao,Suojieduan,Huangjinyupei,Yuhuangjin） on leaves at maize jointing stage on the plant height,stem diameter,leaf area,and yield of maize cultivar Luoyu 4 were studied.The results showed that after spraying chemical control drugs,the plant height was reduced by 13.5～30.3 cm;the leaf area per plant was significantly reduced by 273.62～2 813.36 cm2 in the big bugle stage and filling stage;and the stem thickness was increased by 0.06～0.21 cm.Moreover,spraying chemical control drugs could increase the yield significantly,especially,Yuhuangjin,which could increase the yield by 12.94%.
