【摘要】 通过对内蒙古自治区大豆主栽品种的密度、施磷量、施钾量、种肥氮量、追肥氮量5项农艺栽培技术措施的综合试验研究,系统地分析了5项农艺措施对产量影响的单因素和交互效应,阐明了5项农艺栽培措施的产量效益。实现大豆单产 200kg/667m²以上产量的优化农艺栽培措施是:株数 2.53～2.75×10⁴株/667m²;施磷量（P₂O₅）4.56～5.44kg/667m²;施钾量（K₂O）5.77～6.74kg/667m²;种肥氮量 2.73～3.18kg/667m²;追肥氮量 2.49～2.91kg/667m²。更多还原

【Abstract】 According to studying synthetically five agricultural cultivation technique measures, density, a-mount of P and K applied, basis N and top dressing N applied,with experiments to main planting soybean varietiesin Inner Mongolia. The authors analyzed the single effect and interaction of these five measures, and expounded theyield profit of these five measures. The optilized agricultural cultivation measures to get yield more than 200/667m²were as follow: the plant density was 2.53～2.75×10⁴ plants/667m², amount of P₂O₅ applied was 4.56～5.44kg/667m², amount of K₂O applied was 5.77～6.74k/667m², amount of basis N was 2.73～3.18kg/667m²,and top dressing N was 2.49～2.91 kg/667m².更多还原
