摘要： 为研究主茎亚有限型大豆株型及产量的变化规律，以窄行密植大豆品种‘合丰51’为试验材料，研究不同种植密度条件下大豆品种株高、茎粗、主茎节数及节间长度、倒伏率以及产量的变化规律。结果表明，随着种植密度的增加，株高呈不断增加趋势；茎粗呈不断下降趋势；主茎节数变化幅度不明显，节间长度不断增加，株高增加为节间伸长所致；倒伏率不断增加；产量呈先增加后降低的趋势。上述性状均与种植密度相关性达到极显著水平，并在40 万株/hm2条件下达到最高产量，说明窄行密植大豆品种‘合丰51号’具有较高的密植潜力。

Abstract: The paper aims to explore the plant type change regular of main emi-determinate soybean under different planting density. Soybean for narrow row solid- seeding‘Hefeng51’was used as experimental material and the dynamic change of plant height, stem diameter, stem node number and internode length, lodging rate and yield were determined. The result showed that the plant height increased with planting density increasing. The stem diameter decreased with planting density increasing. The stem node number had on significant change and the internode length increased with planting density increasing. The plant height increased on account of the internode length increasing. The lodging rate increased with planting density increasing. The yield first increased then decreased with planting density increasing. The correlation of all above traits and the planting density reached significant high level, and the highest yield was achieved with the plant density of 40×104 plant/hm2. It shows that the soybean‘Hefeng51’have high density potential.
