To investigate high yield and fine quality cultivation measures of soybean in early mature soybean region of Hebei, the effects of four fertilizer levels and four plant densities on agronomic character,yield and quality of soybean were investigated by split plot design in Baoding and Qingxian. The results indicated that branches,valid pods per plant,seed weight per plant,100-seed weight,yield,content of protein and content of oil had no significant differences under different fertilizer levels. The yield was highest under the fertilizer level of N 75. 0 kg/ha,P2O5 90. 0 kg/ha,K2O 60. 0 kg/ha. Branches,valid pods per plant,seed weight per plant and yield had significant differences among different densities. Yield in Baoding site was highest under the density of 22. 5 × 104 plants/ha,which was 3 350. 00 kg/ha;Yield in Qingxian site was highest under the density of 21. 0 × 104 plants/ha, which was 3 108. 94 kg/ha.Protein and fat contents showed significant differences between different locations,fat content was higher (19. 41%) in Baoding and protein content was higher(45. 47%) in Qingxian. Protein and fat contents kept stable among different combinations of treatment at the same location. The suitable cultivation measures of soybean in early mature soybean region of Hebei were fertilizer level of N 75. 0 kg/ha,P2 O5 90. 0 kg/ha,K2 O 60. 0 kg/ha and the density of 22. 5 × 104 plants/ha.%为探讨河北省夏播早熟区大豆的高产优质栽培措施,在保定和青县采用裂区设计方案,研究了4种施肥水平和4个种植密度对大豆农艺性状、产量和品质的影响。结果表明,不同施肥水平的分枝数、单株有效荚数、单株粒质量、百粒质量、产量、蛋白质含量和脂肪含量差异均不显著,施用纯N 75.0 kg/hm2、P2 O590.0 kg/hm2、K2 O 60.0 kg/hm2肥料水平的大豆产量较高；分枝数、单株有效荚数、单株粒质量及产量在不同密度间存在显著或极显著差异,其中,保定试点22.5万株/hm2密度水平的大豆产量最高,平均为3350.00 kg/hm2,青县试点21.0万株/hm2密度水平的大豆产量最高,平均为3108.94 kg/hm2；不同试点的大豆蛋白质含量和脂肪含量差异极显著,保定平均脂肪含量较高,为19.41%,青县平均蛋白质含量较高,为45.47%,但同一试点不同处理间无显著差异。河北省夏播早熟区大豆的高产优质栽培技术如下：施肥量为纯N 75.0 kg/hm2、P2 O590.0 kg/hm2、K2 O 60.0 kg/hm2,密度为22.5万株/hm2。
