| 摘 要： | 采用五因素五水平旋转回归设计研究了密度、氮肥、磷肥、钾肥、锌肥对玉米产量的影响,结果表明：密度、氮肥与产量间回归关系达极显著水平,锌肥与产量间回归关系达显著水平,磷肥、钾肥与产量间回归关系不显著;并建立了产量回归模型,获得各因素的最优组合,即666.7m2种植6 000株、施用尿素30 kg、过磷酸钙0 kg、氯化钾25 kg、硫酸锌4 kg。表明,在高产栽培中,密度仍是制约玉米产量的最主要因素,尿素的施用量已基本达到玉米生育期的需要,要减少过磷酸钙的施入,增加钾肥和锌肥的施用量。

| Abstract: | The effects of density,nitrogen,phosphorus,potassium and zinc on maize yield were studied by the rotational regression design with five factors and five levels.The results indicated that the regression relationships of density and nitrogen with yield were very significant and that of zinc with yield was significant,but those of phosphorus and potassium with yield were not significant.The yield regression model was established.The optimum combination of the five factors was obtained,that was to say,the densi... |
