摘要
试验采用二次通用旋转组合设计,用较少次数试验实现对较多水平的考察,主要研究水稻秧苗移栽时期和移栽密度对水稻产量的影响及其构成因素对产量的影响程度。分析了产量构成因子对产量影响的差异,建立了水稻品种98-122产量与秧龄和密度的二次回归模型。根据回归模型求出了获得最高产量时,秧龄和密度的取值。
The experiment was conducted to study the effect of different seedling age and density on yield of rice using quadratic general rotary unitized design.The method can observe and study more testing levels with less tests.Factors which influence yield have been studied by grey correlation analysis.Quadratic regression model have been founded among yield,seedling age and density.And the value of seedling-age and density was gotten when the yield was the highest.
