摘　　要：于2013年在大田条件下研究了12种生化制剂和6种复配生化制剂对苗期受渍玉米的影响。结果表明,苯基脲(PU)处理、脱落酸(ABA)处理、抗坏血酸和6-苄基腺嘌呤复配(VC+6-BA)处理、抗坏血酸和表油菜素内酯复配(VC+NBR)处理的净光合速率、产量显著高于淹水不喷生化制剂处理(CK2),且穗重与功能叶光合速率相关性达极显著水平。说明PU、ABA、VC+6-BA和VC+NBR能快速恢复功能叶的光合能力,从而提高穗重,可以作为缓解玉米苗期渍害的有效生化制剂。Twelve biochemical reagents and 6 of their combinations were used to study their influences on water- logged maize in seedling period in 2003 in field. The results showed that the photosynthetic rate and yield of the maize treated by Phenylurea（ PU）,ABA,VC ＋ 6- BA and VC ＋ NBR were significantly higher than those under water logging but not treated by biochemical reagents. And the correlation of ear weight with photosynthetic rate of functional leaf was very significant. Spraying the above four biochemical reagents could rapidly recover the photosynthetic ability of leaves,which was the cause for increasing spike weight,so they were the effective reagents to relief water logging of maize in seedling period.
