摘　　要：以基因型不同、表现型有差异的两个玉米单交种进行2∶2间作,试验表明:玉米不同品种的合理间作可显著提高产量,增产幅度可达10%;增产的主要原因在于群体结构的改善,当代杂种优势所起的作用十分有限。The inter-planting experiment using two kinds of maize hybrids of different genes and phenotypes by the pattern of 2：2 was carried. The study indicated that the reasonable inter-planting of different maize varieties could enhance the yield remarkably which increased by 10%. The improvement of the community structure was the main reason for yield-increasing. And the effect of heterosis of F0 generation was extremely limited.

关 键 词：玉米 间作 群体结构 产量
