| 摘 要： | 为探讨密度与施肥对大豆产量及产量性状的影响,采用裂区试验设计研究了吉育35在不同密度与施氮水平下的产量及产量性状.结果表明:密度对单株荚数、单株粒数、单株荚重的影响均达到显著水平,随密度增加,单株荚数、单株粒数、单株荚重降低.施氮对单株荚数、单株粒数的影响达到显著水平,随施氮量增加,单株荚数、单株粒数增加,施氮对单株荚重影响未达到显著水平.密度与施氮对百粒重的影响均未达到显著水平.密度与施氮对产量的影响均达到极显著水平,随密度增加,产量先增后降,随施氮量增加,产量增加.密度为220000株·hm-2、施氮量为90kg·hm-2处理的产量最高.

| Abstract: | This study was carried out to discuss the effects of planting densities and N-fertilizer levels on yield and yield characteristics.A split-plot design with the planting densities as main plot and N-fertilizer levels as sub-plot was adopted and the effects of planting densities and N-fertilizer levels on yield and yield characteristics of Jiyu35 were studied.The results showed that the effects of planting densities to the pods number per plant,the grains number per plant and the pods weight per plant were so... |
