摘要: 运用三因素五水平二次正交旋转组合试验设计方法,研究了川中丘区川单15播种期、种植密度和氮化肥用量对产量及其主要经济性状的影响,并建立了相应的数学模型,得出在直播条件下产量6.0t/hm2以上的高产栽培技术方案为:播种期4月6日~17日、种植密度6.1~6.6株/m2,氮化肥用量250~300kg/hm2

Abstract: A field experiment of quadratic orthogonal regressive rotation design of three factors was conducted. The mathematical models of sowing date, planting density and application rate of nitrogen for high-yielding and other economic characters were established and the scheme of cultural practices for yielding above 6.00t/hm2 was computed from the model as follows:sowing from 6~17 of April at the densities of 6.1~6.1 plants/m2, applying the fertilizers N 250~300kg/hm2.

Key words: HYBRID MAIZE, MATHEMATICAL MODEL, CULTURAL PRACTICE
