摘要: 采用二次回归正交旋转组合设计研究了不同生态区玉米新杂交种川农单交9号籽粒产量与密度、氮肥、磷肥的定量关系,建立了产量形成的密度,肥料反应模型,并通过对模型的解析,求出了各因素对产量影响的主次关系及相互作用,寻出定量生产水平下的最佳农艺措施。本文得出的玉米高产栽培综合农艺措施为:盆中、盆周和盆东高产区亩植密度3500株左右,亩施有效氮约11.0公斤,有效磷约5.0公斤;盆东低产地带亩植2813-3271株,亩施有效氮9.6-11.6公斤,有效磷3.2-5.2公斤。

Abstract: The relationships on grain yield of the new maize hybrid CHUANNONGDANJIAO 9 of maize with density, nitrogen and phosphorus were studied, and a mathematical model involving the three factors which affect yield was established by using the orthogonal rotation design of quadratic regression in the different ecological regions. The effects of inividual factor and its interaction on yield were determined and the optimum agronomic practices in certain conditions were found by analysing the model. The optimum comprehensive practices for high yield of the hybrid were, density of about 3500 plants, about 11.0 KG Navailable and about 5.0 KG P2O5 available per mu in the centre of the Sichuan Basin and around and in the high yield regions of the east, and density of 2813-3271 plants, 9.6-11.6 KG N available and 3.2-5.2 KG P2O5 available per mu in the lower yield regions of the east.
