摘要
用二次通用旋转组合设计,分析了广两优676产量与种植密度、氮、钾施用量间的关系,建立了各因素与产量指标的数学模式,确立了广两优676高产栽培的优化方案:每667m^2种植密度1.48万~1.71万穴,施纯氮8.29~11.87 kg,施纯钾7.27~10.73 kg。
This study analyzed the relationship between yield with plant density, nitrogen rate, potassium rate by adopting quadratic general spinning design, created yield formation mathematical model. Based on the model, the optimized cultivation techniques were : 14.8-17.71 thousand plants per hill, nitrogen and potassium application rate 8.28-11.87kg per 667m^2, 7.27-10.73 kg per 667m^2 respectively.
