摘要
利用3种株型的6个大豆品种,设置高(25株/m2)、中(20株/m2)、低(15株/m2)3种密度,研究了株高、主茎节数、分枝数、单株荚数、单株粒数、百粒重、单株粒重和产量诸性状不同株型与种植密度的关系。结果表明,株高和主茎节数的品种与密度互作效应显著,但其他性状的互作效应未达显著水平。单株荚数、单株粒数和单株粒重在密度和品种间都有显著差异,但小区产量在密度间的差异未达显著水平。在供试品种中,以圆叶中等分枝型的B2和B1的产量较高,分枝型的B5和B4居中,而尖叶单秆型的B6和B3的产量较低。
The results showed that there was significant interactional effect between variety and density for plant height and No. of node The differences of No. of seed and seed weight per plant among densities were significant, So was it among varieties. The difference of plot yield among were not significant. The yield of variety B2 and B1 were higher and B6 and B3 were lower.
