| 中文摘要: |
| 采用二次回归正交旋转组合设计，研究杂交玉米新品种高瑞171 产量与栽培密度及氮、磷、钾肥施用量的关系，建立了各因素与产量的数学模型。对高瑞171产量影响大小依次为栽培密度>施氮量>施磷量>施钾量。提出了高瑞171获得9558 kg/hm2以上产量的栽培密度及N、P、K肥施用量的优化组合方案：即栽培密度41768~44395株/hm2,施氮量193.34~249.39 kg/hm2,施磷量128.90~179.79 kg/hm2,施钾量92.9~131.09 kg/hm2.其目的是为发挥该品种最大的增产潜力\为加速大面积推广提供指导。 |

and planting density and nitrogen, phosphorus, potassium fertilizer application relationship, building mathematical models of the various factors and yield. The size effect on maize yield were Gaorui 171 planting density and amount of nitrogen, phosphorus and potassium. The great Gaorui 171 above 9 558 kg/hm2, yield of planting density and N, P, K fertilizer optimum combination scheme: the planting density of 41768~44395 strain/hm2, N 193.34~249.39 kg/hm2, P 128.90~179.79 kg/hm2, potassium 92.9~131.09 kg/hm2. Its purpose is to play the production potential, the largest species provide guidance to accelerate large area promotion. |
