摘　　要：为明确垄作行间非等量播种技术对小麦群体及冠层性状的影响,研究了垄上不同密度的垄作模式对小麦群体的冠层结构和光辐射的影响。结果表明,T5处理(垄上边行比内行播量增加30%)的群体结构最为合理,冠层光截获较多,光能利用率最高,产量也最高。In order to understand the effects of Non-equivalent Sowing Technique on the development of wheat population and canopy structure,the change of light radiation and the canopy structure of bed planted winter wheat under different level of intensity was investigated.The results showed that the treatment T5 could lead to the highest yield in this experiment.And the crest layer structure of T5 treatment（the seeds sown in side row in bed-planting was increased up to 30% than that of in inner row）performed the best.The plants in treatments T5 had reasonable canopy architecture than others,could intercept more solar radiation.
