| 摘 要： | 以高产优质夏大豆邯豆5号为材料,采用四元二次回归正交旋转组合设计,研究种植密度和氮、磷、钾施肥量对邯豆5号产量的影响,建立了产量与种植密度和肥料之间的数学模型。结果表明,对邯豆5号产量的影响施磷量(X3)>施氮量(X2)>施钾量(X4)>种植密度(X1);邯豆5号理论产量的最大值为4399.5kg/hm2,相应的栽培措施是密度22.5万株/hm2,N120kg/hm2,P2O5180kg/hm2,K2O75kg/hm2。

| Abstract: | Four-factor quadratic rotational regression combination design was used to study the influence of planting density and different NPK on the yield of Handou No-5.The mathematical models among yield,planting density and fertilizer were proposed on the basis of field experiment results.Results showed that the greatest effect on yield of Handou No-5 was phosphate fertilizer;the second was nitrogenous fertilizer;the next was potassium fertilizer;and the smallest was planting density.The highest theoretical yield... |
