摘  要：
针对内蒙古大豆主产区 ,以蒙豆 5号品种为试验材料 ,在旱作条件下 ,通过对不同施氮、磷、钾量和密度四项农艺栽培措施与产量形成的关系研究 ,建立了四项农艺措施与产量关系的数学模型。通过对数学模型的优化解析 ,提出了单产 175kg/6 6 7m2 以上目标产量的优化农艺栽培措施组合方案 ,即密度以 2 .0 5 - 2 .19× 10 4 株 /6 6 7m2 、施磷 (P2 O5)量 4 .0 - 5 .5kg/6 6 7m2 、施钾 (K2 O)量 3.7- 4.4kg/6 6 7m2 、施氮 (N)量 4 .0 - 4.7kg/6 6 7m2 。经田间试验验证 ,模型和提供的优化方案可行 ,对生产实践具有重要的理论意义和应用价值。除单株荚数随着密度降低而增加外 ,单株粒数、荚粒数、百粒重及产量均随密度、施肥量增加而呈单峰曲线变化。

摘  要：
Mathematic model to describe the relation between yields and four cultivation measures was set up in the main soybean productions area of Inner Mongolia, taking Mengdou 5 as experiment material under dry farming condition, through studying the relation between different amount of N、P 2O 5、K 2O applied, different seeding rates, four cultivation measures and yield constituents; According to optimum analyzing the model, the cross scheme of optimum agricultural cultivation measures that the goal yields was above 175kg/667m 2 was put forward, namely the density was 2.05-2.19×10 4 plants/667m 2, amount of N,P 2O 5,K 2O was 4.0-4.7kg/667m 2,4.05-5.5 kg/667m 2,3.7-4.4 kg/667m 2 rspectively. It had been proved that the model and the optimum scheme were feasible by experiments, and had significant theoretical meaning and applied value. The change curve of seeds/plant,seeds/pod、100-seed weight and yield all took on single-peak curve along with the increasing density and fertilization, besides the pods/plant increases along with the reduction of density.
