| 中文摘要: |
| 对小麦/玉米复合群体中不同玉米群体的叶面积指数、光合速率及产量要素间的关系进行研究，结果表明：不同玉米群体的叶面积指数和光合速率的变化趋势均呈抛物线型，二者呈显著正相关；光合速率与经济产量相关极显著；两种带型中，6行小麦2行玉米，玉米密度为6.75万株/hm2的玉米群体平均光合速率最大，经济产量最高，6行小麦3行玉米，玉米密度为6.00万株/hm2的玉米群体光合速率和经济产量次之。 |
| 英文摘要: |
| The relationship between leaf area index, photosynthetic rate and yield with different maize populations in the wheat/maize intercropping was studied. The results showed that the curves of LAI and Pn of different maize populations were parabolas, and the correlation between Pn and LAI was significantly positive. So improvement of the photosynthetic rate could increase maize yied. In two intercroppings, the average photosynthetic rate and the maize yied in A1D3 was the largest, while those in A2D2 was the second. |
