为探索出花生吉花1号合理的种植密度及最优施肥方案,本研究采用四因子五水平正交回归旋转设计,建立了各因素与产量指标的优化数学模型,确立了高产优化栽培方案。研究结果表明:各因素对产量的影响效应表现为:种植密度>氮肥>磷肥>钾肥,产量大于3 300.00 kg/hm~2目标产量的优化栽培方案为:种植密度13.292万~13.767万穴/hm~2;施氮(N)量每公顷应达到217.7~241.1 kg,施磷(P2O5)量每公顷应达到179.52~206.36 kg、施钾(K_2O)量每公顷应达到191.68~210.68 kg。 In order to explore the reasonable planting density and the optimal fertilization plan of peanut jihua No.1, the orthogonal mathematical model of four factors and five levels was established in this study. The optimized mathematical model of each factor and yield index was established and the plan of high yield and optimized cultivation was established. The results showed that the effects of various factors on the yield were as follows: planting density> nitrogen fertilizer> phosphate fertilizer> potash fertilizer, and the optimal cultivation plan of the target yield of more than 3 300.00 kg / hm ~ 2 was as follows: planting density 132,900 ~ 137,600 ~ 2; the amount of nitrogen application should reach 217.7 ~ 241.1 kg per hectare. The amount of P2O5 should reach 179.52 ~ 206.36 kg per hectare and the amount of K_2O should reach 191.68 ~ 210.68 kg per hectare.
