化控剂对玉米生长发育的影响

Effect of Chemical Control Agent on Maize Growth and Development

为了明确化控剂对玉米生长发育的影响,在玉米拔节期喷施不同剂量玉丰保及在玉米11片展开叶时喷施不同化控剂,并调查施药后玉米地上部鲜重、叶面积指数、株高、节间长度、穗长、穗粗、秃尖长、百粒重及产量的变化情况。结果表明:在玉米11片展开叶时施用玉丰保,对增加玉米叶面积指数,控制株高,增加茎秆粗壮具有很好效果。

In order to clear the influence of control agent on maize growth and development, different doses of Yufengbao leaf fertilizer and other control agents were sprayed in maize jointing stage and 11 leaves,the chan- ges of overground fresh weight, leaf area index, plant height, internode length, length of ear, diameter of ear, length of bald tip, 100-grain weight and yield were researched. The results showed that the treatment spraying different doses of Yufengbao leaf fertilizer in maize 11 leaves had good effect to increase maize leaf area index, control plant height and increase stem stout.
