[目的]探明夏大豆(Glycine max)获得3000 kg/hm2产量的适宜种植密度和施肥技术.[方法]采用四元二次回归正交旋转组合设计,研究密度和施肥量对夏大豆产量的影响,并进行寻优.[结果]影响夏大豆产量的顺序是:施氮量>施磷量>密度>施钾量.夏大豆获得3000 kg/hm2以上产量的各因素最佳取值范围是:种植密度20.6万~23.2 万/hm2,施氮量83.5 ~ 95.2 kg/hm2,施磷量57.1~73.1 kg/hm2,施钾量43.0~ 52.0 kg/hm2.[结论]该研究可为夏大豆高产栽培技术集成提供科学依据.%[Objective] The purpose was to explore the suitable planting density and fertilizer technology of summer soybean to obtain 3000 kg/hm2 yield. [ Method] The quadratic regression orthogonal rotational combing design with four factors was used to study the effects of planting density and fertilizer on summer soybean yield, and find out the most optimized factors value. [ Result] All factors'effects on summer soybean yield was in order: Nitrogen fertilizer > phosphorus fertilizer > planting density > potassium fertilizer, and the best value range was: planting density 20.6×104 - 23. 2×104 per ha, nitrogen fertilizer 83.5 -95.2 kg/hm2, phosphorus fertilizer 57.1 -73.1 kg/hm2, potassium fertilizer 43.0 -52. 0 kg/hm2. [ Conclusion] The study provides a scientific basis for integrating high yield cultivation technology of summer soybean.
