摘　　要：为了探讨化控剂对玉米抗倒伏性状及产量的影响,以安徽省阜南县为试验地点,通过对30%胺鲜酯·乙烯利水剂处理组和清水处理组的比较分析,发现30%胺鲜酯·乙烯利水剂处理组的株高、穗粗、穗长、茎粗和千粒质量普遍较清水处理组低,降幅在2%~18%,显示出明显的负面影响;在产量和抗倒伏能力方面,处理组的产量下降约6%~9%,空秆率降幅约15%~41%,倒伏率降幅约50%~75%,表明该化控剂有助于降低空秆率和倒伏率,提高玉米的抗倒伏性能力。分析结果显示,30%胺鲜酯·乙烯利水剂在提高玉米抗倒伏抗性方面表现出良好效果,但对玉米的生长指标产生一定负面影响,在实际应用中需综合考虑化控剂的利弊,选择合适的使用方式以实现最佳效果。This study was conducted in Funan County to investigate the effects of chemical control agents on lodging resistance and yield of maize.The results of comprehensive analysis showed that 30%aminosyl and ethethylene water had a good effect on improving the lodging resistance of maize,but had a negative effect on the growth index of maize.Therefore,the advantages and disadvantages of chemical control agents should be considered comprehensively in practical application,and the appropriate use mode should be selected to achieve the best effect.This study provided a useful reference for corn production,and also provided a basis for further optimizing the use of chemical control agents.
