摘　　要：通过不同种植方式对玉米的群体光合性能、干物质积累及产量进行研究。结果表明:适当的宽窄行配比可使其群体保持较高的叶面积指数,且中后期叶面积指数衰减较慢,漏光损失较少,净光合速率提高,群体干物质积累量增加,为获得玉米高产奠定了基础。The photosynthesis capacity, dry matter accumulation and yield of spring maize on different planting patterns and maize community construction were analyzed. The results showed that the community construction was improved, the competition among individuals reduced, the growth of individuals improved, the leaf area, LAI were increased to different extent under appropriate double rows on a big ridge cultivation. So it can efficiently improve the illumination condition through maize community, photosynthesis capacity and utilization ratio of light energy were improved, yield of spring maize were also increased.
