摘　　要：以玉米新品种中单808为主要材料,在不同种植模式下对灌浆期生理生态指标、产量和经济效益进行比较分析。结果表明,在比空和间作条件下,中单808的各项指标显著高于清种;套作和比空条件下,经济效益较高。从而说明套作、比空栽培对玉米生长发育和产量的提高起到促进作用,玉米比空栽培和玉米马铃薯套作模式可以在生产中推广。Comparison of physiological traits at grain filling stage, yield and economic benefit of maize hybrid ＂Zhongdan808＂ was made under intercropping, interplanting, alternating and single cropping. The results indicated that the physiological traits of alternating, intercropping farming of maize Zhangdan808 were significantly higher than single cropping. The economic benefit was higher under interplanting and alternating farming. It proved that interplanting and alternating cropping had the favorable effects on growth and yield of Zhongdan808, and maize alternating and maize-potato interplanting were more reasonable planting methods.
