| 摘 要： | 选用辽宁省高油大豆品种辽豆14号和辽豆11号，探讨了不同株行距对两个品种的农艺性状和产量表现的影响。结果表明：随着种植密度的增加，株高增高，主茎节数、分枝数减少，单株有效荚重降低，百粒重下降。叶面积指数随种植密度增加呈上升趋势，单株叶面积和干物质积累呈下降趋势。品种、种植密度间产量差异达极显著水平，而行距间产量差异不显著。

| Abstract: | A appropriate planting density and feasibility of narrow-row spacings for higher yield in soybean were discussed by investigating the effects on agronomic, physiological characteristics and yield in two high oil varieties Liaodou 11 and Liaodou 14 under different spacings. With the increase of planting density, plant height was increased, while node number, branch number and pod weight per plant were decreased, and the 100-grain weight was declined slightly. Although LAI was increased, the leaf area per plant and dry matter accumulation was decreased. Significant yield differences were observed among varieties and different planting density, but no significant differences were found under different row spacings. |
