摘　　要：为了提高杂粮作物的产量及效益,根据玉米全程机械化种植发展要求,创新地设计出了"夏玉米—绿豆全程机械化间作模式",通过研究,为现代高效农业新型种植模式提供理论依据。研究结果表明,全程机械化间作模式下,夏玉米产量随着玉米密度的增加呈增加趋势,玉米千粒重和穗粒数逐渐降低;不同密度间绿豆产量差异不明显。玉米密度对间作经济效益影响极显著,且是影响间作效益的第一因素。玉米—绿豆间作处理的净产值均显著高于单作处理,且有效提高了土地利用率。推荐玉米75000株/hm2+绿豆90000株/hm2、玉米75000株/hm2+绿豆105000株/hm22种净产值最高的间作模式推广应用。According to the requirement of fully mechanical development ot maize planting, a Iuuy mecnamcal inter-cropping pattern between summer maize and m an was innovatively designed and fully discussed to increase the yield and benefits. The theoretical basis will be provided for the modern efficient agriculture planting pattern by this research. The results showed that there was a positive relationship between the yield growing and density increasing of the summer maize as its thousand-seed weight and kernel number decreasing in this inter-cropping pattern; the yield of mungbean had no significant differences between different densities. The density of maize was the main factor which significantly affected the economical efficiency of intercropping crops. Compared to the mono-cropping, the inter-cropping of maize and mungbean increased not only the net output, but also the efficiency of land utilization. The author identified two combinations which had the highest net output, they were 75000 plants maize with 90000 plants mungbean and 75000 plants maize with 105000 plants mungbean per hectare.
