摘要： 为了防止玉米倒伏，实现高产稳产，采用化控剂-乙烯利处理，研究其对玉米主要性状的影响。结果表明：经化控剂-乙烯利处理棒三叶长、基部节间长、株高、穗位、穗长和单株平均产量均低于对照，其中对棒三叶长、基部节间长的抑制效应前期>中期>后期，同一时期，随着处理剂量的增加棒三叶长、株高、穗位、穗长、单株产量逐渐减小，而基部节间长差异不明显。随着处理时期的推迟，穗位高表现高—低—高的变化趋势；株高逐渐下降；穗长变化不明显；除乙烯利使‘金丰50’减产幅度呈现低—高—低的变化外，采用烯施美处理‘金丰50’和AH2067，或采用乙烯利处理AH2067，减产幅度均呈现高—低—高的变化趋势。化控剂-乙烯利对籽行数和秃尖长影响不明显。

Abstract: In order to prevent lodging, to achieve high and stable maize was treated by chemical control agent-ethephon to study its effect on main traits. The results showed that, characters of length of three ear-leaves, basal internode length, plant height, ear position, ear length and individual plant yield of maize treated was lower than that of the control, which inhibitory effect of length of three ear-leaves , internode length followed the turns: earlier stage >mid stage >late stage. At the same time, with the dose increasing length of three ear-leaves, plant height, ear position, ear length and individual plant yield decreased gradually and internode length showed no significant difference. With the time delaying, height of ear position showed the tendency of high - low - high; plant height gradually decreased; ear length didn’t change significantly; Except for yield decreasing reduction of ‘Jinfeng 50’ by ethephon showing the following tendency of low - high - low, yield decreasing reduction of ‘Jinfeng 50’ and AH2067 by “XISHIMEI”, or AH2067 by ethephon showing the tendency of high-low-high. Effect of chemical control agent on the ear rows and bald length was not significantly affected.
