摘　　要：以浙秋豆2号为试材,分析了不同播种期与种植密度对其主要经济性状的影响。结果表明:早播稀植可极显著增加浙秋豆2号的单株有效荚数、单株实粒数和干籽百粒重。随着播期推迟,种植密度对单株实粒数的影响不显著;适当的早播密植能够极显著提高浙秋豆2号的产量。Field experiments with soybean cultivar Zheqiudou 2 were carried out under different seeding dates and planting densities in order to analyze the effects of seeding date and planting density on major economic traits of the cultivar.The results showed that early seeding and thin planting could very significantly increase the effective pods per plant,the filled grains per plant and the dry 100-grain weight,but thin or thick planting had not a significant effect on the filled grains per plant when the seeding date was late.Appropriate early seeding and thick planting could very significantly improve the yield of the cultivar under the current experimental conditions.
