| 摘 要： | 以双低油菜苏油4号为材料进行田间试验，研究了种植密度对籽粒品质的影响。结果表明：苏油4号的适宜密度范围为12万～15万株／km2；增加密度主要通过增加群体中有效角果数而提高产量；增加密度明显削弱各枝序的生长，其中对二次分枝生长的影响最大；随着密度的增加籽粒的含油率逐渐提高，蛋白质含量较为稳定。

| Abstract: | The field experiments with the double-low-content rape cultivar Suyou 4 were carried out under different planting densities in order to study the appropriate planting density and its effect on the rapeseed quality.The results were as follows.The appropriate planting density of Suyou 4 was between 120 000～150 000 plants/hm~2;Increasing the density mainly made the effective pod number increase so as to improve the yield;Increasing the density obviously weakened the branch growth,especially the secondary branch growth;As the density increased,the rapeseed's oil content gradually improved,but the protein content was relatively stable. |
