| 中文摘要: |
| 采用四元二次正交旋转回归组合设计方法，研究种植密度、氮素、磷素和钾素水平对玉米新品种桂单
591 产量的影响。结果表明: 4种栽培因素对桂单591 产量的影响顺序为氮素跃密度跃钾素跃磷素，在较大种植密度，氮
肥充足时获得高产。桂单591 的高产综合配套栽培措施: 密度57 750耀61 255 株/hm2、施氮量185.44耀261.53 kg/hm2、
施磷量86.81耀122.20 kg/hm2、施钾量153.79耀222.21 kg/hm2可获得8 250.00 kg/hm2以上的籽粒产量。 |
| 英文摘要: |
| In this experiment, the effects of planting density, nitrogen, phosphorus and potassium on the maize yield of
new variety Guidan 591 were studied with orthogonal experiment by a quadratic, orthogonal and pivoting regression for four
factors. The result showed that the influence of four factors on the maize yield of Guidan 591 was in order of nitrogen,
planting density, potassium and phosphorus. To gain high yield, certain planting density, ample nitrogen were needed. The
optimal agronomic conditions were described as follows: planting density was 57 750耀61 255 plants/hm2, applying pure
nitrogen 185.44耀261.53 kg/hm2, P2O5 86.81耀122.20 kg/hm2, K2O 153.79耀222.21 kg/hm2, and then the high maize yield of
above 8 250.00 kg/hm2 was obtained. |
