试验采用二次通用旋转组合设计，研究了不同肥料及密度条件对大豆德豆17产量的影响，建立了以德豆17产量为目标函数的数学模型。结果表明：各栽培因子对德豆17产量的影响为：钾肥〉密度〉磷肥〉氮肥〉微肥。经计算，初步确定了德豆17号在当地产量大于175．00kg／667m^2的栽培方式为：密度0．81-0．83万株／667m^2，氮肥施用量19．46-20．29kg／667m^2，磷肥施用量39．09-40．91kg／667m^2，钾肥施用量21．97-23．04kg／667m^2，微肥施用量O．92-1．08kg／667m^2。

A second universal revolving combination design was used to study the effects of fertilization and crop density on DeDoulT, and a math model as the goal of DeDou17 yield was established. The result showed that the influence of cultivation factors on DeDou17 yield as followed： K〉crop density〉P〉N〉microelement fer- tilizers. When local yield was more than 175 kg per 667m2, it preliminary identified the best cultivation mode for the yield of DeDou17 as followed： the density was between 8 100 and 8 300 per 667m2; the nitrogen fertilizer was between 19.46 and 20.29 kg per 667m2; the phosphate fertilizer was between 39.09 and 40.91 kg per 667m2; the kalium fertilizer was between 21.97 and 23.04 kg per 667m2; the microelement fertilizer was between 0.92 and 1.08 kg per 667m2.
