| 摘要: |
| 通过间作与相应单作的比较证实了小麦玉米间作具有明显的间作产量优势，施肥对这种间作优势有促使作用。间作优势在光资源的捕获利用方面的表现主要是其提高了PAR的捕获效率而非利用效率。小麦相对于玉米的竞争力更强，施肥有缓解这种强烈竞争的作用。 |

| Abstract: |
| The comparison of intercropping and corresponding single cropping proved that wheat/maize intercropping had strong advantages in yield,which could be further supported by fertilization.The intercropping advantages,in light resource capture and utilization,were to raise PAR capture efficiency rather than its conversion efficiency.The competitive ability of wheat for PAR was much greater than that of maize,which could be alleviated with fertilization. |
| Key words: strip intercropping,dry matter accumulation,intercropping advantage,light resource capture |
