摘　　要：为从玉米(Zea mays L.)品种的角度优化胶东地区小麦-玉米复种模式,选择玉米品种金海5号、郑单958、先玉335作为试验材料,在胶东地区进行半夏种植,对其基本性状进行对比研究。结果表明,成株叶片数方面,金海5号显著低于郑单958和先玉335;株高方面,先玉335显著高于郑单958和金海5号;抗倒伏能力方面,金海5号与先玉335优于郑单958;果穗的生长状况方面,郑单958优于先玉335,金海5号最差;玉米螟抗性方面,从强到弱依次为郑单958、金海5号、先玉335;理论产量方面,3个品种差异不明显;郑单958对丝黑穗病抗性较差。综合来看,先玉335为在胶东地区进行半夏种植较为理想的玉米品种。In order to optimize the wheat-maize double cropping system from the perspective of maize(Zea mays L.)varieties,maize varieties Jinhai No.5,Zhengdan 958 and Xianyu 335 were selected as experimental materials and planted in early summer in Jiaodong region,and their basic traits were compared and studied.The results showed that the number of leaves of Jinhai No.5 was significantly lower than that of Zhengdan 958 and Xianyu 335;In plant height,XY335 was significantly higher than that of Zhengdan 958 and Jinhai No.5;In lodging resistance,Jinhai No.5 and Xianyu 335 were better than Zhengdan 958;In growth traits of maize ears,Zhengdan 958 was better than Xianyu 335,while Jinhai No.5 was the worst;In resistance to corn borer,the order from strong to weak was Zhengdan 958,Jinhai No.5 and Xianyu 335;In theoretical yield,there was no considerably difference among three varieties;In disease resistance,Zhengdan 958 was less resistant to maize head smut.In conclusion,Xianyu 335 is an ideal maize variety for early summer planting in Jiaodong region,China.
