| 摘 要： | 采用二次回归２０６最优设计，探讨了晋中水地麦区麦后育苗移栽玉米晋单３２号的栽培技术措施。研究表明，移栽玉米只有合理配置种植密度和氮磷肥用量，才能获得高产。并得出了单产高于７５００ｋｇ／ｈｍ２的优选技术配合为：密度６００００～６９０００株／ｈｍ２，施Ｎ１１５０７～１８８３７ｋｇ／ｈｍ２，施Ｐ２Ｏ５５７５４～９４１９ｋｇ／ｈｍ２。

A Study on Density and Application of N-P 2O 5 of Transplanted Corn |

| Abstract: | The experiments were conducted in Taigu, within the Mid Jin, irrigated winter wheat region, at a temperature of more than 10℃, with an annual accumulated temperature of 3 600～3 800℃. A corn variety seedling, Jindan 32, was transplanted from the nursery to the field after harvesting the winter wheat. The experiment used 2 factor two order regression design of D optimization. The two factors affecting transplanted corn productivity were 1) density of planting and 2) a single application of nitrogen phosphate. The study established mathematical models of corn grain yield response to the above factors. On the basis of this model, it provided optimum combination for density and application of N-P more than 7 500kg/hm 2 |
