摘要： 为了研究苯唑草酮对玉米地常见杂草防效和不同甜玉米品种对苯唑草酮的敏感性，试验选取了种植较为广泛的16个甜玉米品种，在幼苗4~6叶喷施25.00 g/hm2苯唑草酮，统计杂草防效及株高抑制率。试验结果表明，苯唑草酮对玉米地常见杂草的防效达到90%以上；苯唑草酮对甜玉米幼苗生长产生一定药害，其中‘中甜8号’和‘正甜68’较为敏感，施药后10天株高抑制率分别为24.83%和23.01%；甜玉米的含糖量与对苯唑草酮的敏感性没有相关性。

Abstract: In order to study the effects of topramezone on common weed control in corn and the sensitivity of different sweet corn cultivars to topramezone, 16 kinds of sweet corn cultivars were treated by 25.00 g/hm2 topramezone at 4-6 leaf stage, the effect of weed control and the inhibition rate of plant height were calculated. The results showed that, topramezone provided a control of 90% on common weeds; effects of topramezone on sweet corn seedling growth could have some phytotoxicity injury, the inhibition rate of plant height to ‘Zhongtian No.8’ and ‘Zhengtian 68’ were 24.83% and 23.01% at 10 days after application, they are more sensitive than other; the sugar content of sweet corn has no correlation with sensitivity to topramezone.
