摘要
以小麦玉米平作为对照,研究了北京地区小麦/玉米/玉米间套作模式下,小麦、玉米的高产和光合性能。结果表明,2.7 m带宽的麦玉玉间套作的平均产量为18 871.5 kg/hm2,比麦玉平作增产20.19%。并且,构建了较为理想的光合群体结构,光合性能改善,其中小麦的光合速率较对照提高30.29%,夏玉米的光合速率较对照提高14.54%。
With the flat planting of wheat and corn as CK, the high yield and photosynthetic character under the intercropping mode of where/com/com in Beijing area were studied. The results showed that the average yield of wheat-corn-corn intercropping with stripe width of 2.7 m was 18 871.5 kg/hm^2, increasing 20.19% that the flat planting of wheat and com. Besides, the more perfect photosynthetic group structure was set up and the photosynthetic character was improved, in which the photosynthetic rates of wheat and summer corn increased 30.29% and 14.54% than that of CK resp.
