Study on High-yield Cultivation Technology of Maize Variety Qiaoyu 8

[目的]研究玉米品种桥玉8号高产配套栽培技术。[方法]采用四因素五水平二次回归旋转组合设计,研究了密度和氮、磷、钾肥施用量对玉米品种桥玉8号产量形成的作用效应,建立回归模型并分析各因子的作用规律。[结果]不同因素对桥玉8号产量影响程度由大到小依次为密度、施氮量、施钾量、施磷量;桥玉8号产量大于11 238.92 kg/hm^2的农艺措施优化方案为密度62 322~63 678株/hm^2、施氮量255~285 kg/hm^2、施磷量85~95 kg/hm^2、施钾量85~95 kg/hm^2。[结论]该研究为加快桥玉8号产业化的进程提供理论依据。

[ Objective] To research the high-yield cultivation technique of maize variety Qiaoyu 8. [ Method] Four-factor five-level quadratic re-gressive rotation combination design was adopted to research the effects of N, P and K application doses on the formation of maize variety Qiaoyu 8. Regression model was established and the functional rule of each factor was analyzed. [Result] The influencing degrees of different factors on the yield of Qiaoyu 8 from big to small were in the order of density, N application dosage, nomic measures optimization scheme of Qiaoyu 8 yield greater than 11 238. 92 kghm2 was as follows 62 322 - 63 678 plants/hm2 , 255 - 285 kghm2 N application dosage,85 -95 kghm2 P application dosage and 85 -95 kghm2 K application dosage. [Conclusion] This research provided theoretical foundation for the acceleration of industrialization process of Qiaoyu 8.
