本文在总结群众性创造“吨粮田”实践基础上,采用五元二次通用旋转设计,选择密度、农肥、氮肥、磷肥、钾肥等五项因素对旱作条件下春玉米吨产技术体系进行试验研究.通过电算分析提出了玉米吨产技术体系数学模型和优化方案,为辽西半干旱地区旱作玉米实现吨产提供了理论依据和配套技术. On the basis of summarizing the mass practice of creating “tons of grain field”, this paper studied the technical system of spring corn tonnage production under the condition of dry cultivation on the basis of five factors, such as five universal quadratic rotation design, selection density, agricultural fertilizer, nitrogen fertilizer, phosphate fertilizer and potassium fertilizer The mathematical model and optimization scheme of corn tonnage production technology system are proposed through computer analysis, which provides the theoretical basis and supporting technology for the realization of tonnage of dry corn in western Liaoning semi-arid area.
