| 摘 要： | 对边行和内行设置了不同密度水平,研究了垄作模式下小麦的边际效应。结果表明,垄作模式下小麦的边行优势较为突出,边行较内行增产较多,最优群体产量较常规方式增产,内行小麦在大群体下产量显著下降。试验范围内T5处理的群体结构最为合理,个体和群体生产力得以协调发展,产量最高。 |
| 关 键 词： | 冬小麦 垄作 边际效应 密度 |

| Abstract: | The edge effect of winter wheat in bed planting system was studied under different density treatments.The result showed that the winter wheat had remarkable marginal effect in bed planting system.The yield was higher in outer rows than in inner rows.The Bed-planting model was better than the conventional planting model.The yield of inner rows decreased markedly under high seed rate cultivation.The highest yield came from the treatment T5 because of its rational colony structure and harmonious relationship between individuals and population. |
