| 摘 要： | 通过不同密度及施氮量对玉米群体光合性能、干物质积累及产量进行研究。结果表明,适当的密度及施氮量可使其群体维持较高叶面积指数的时间延长、漏光损失减少、净光合速率提高,延缓中后期叶片衰老进程,达到活秆成熟,使群体干物质积累量增加。

| Abstract: | The photosynthesis capacity, dry matter accumulation and yield of maize in sowing density and applying nitrogenous fertilizer and maize community construction were analyzed. The results showed that the community construction was improved; the leaf area and LAI were increased to different extents under appropriate sowing density and applying nitrogenous fertilizer. So it could efficiently improve the illumination condition through maize community, photosynthesis capacity and utilization ratio of light energy were improved, slow the leaves maturity and harvest alive, the dry matter accumulation increased. |

| Keywords: | Maize Density Applying nitrogenous fertilizer Photosynthetic capacity Dry matter accumulation |
