摘要
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 optimal planting density and fertilizer scheme of ＇ Jihua 1＇ peanut, four factors and five levels regression rotation design was adopted in the experiment. Optimized mathematical model of each factor and yield index was established, and high-yield cultivation and optimization scheme was determined. The results showed that the influence degree of each factor on Jihual yield was density〉 N 〉 P 〉 K. The optimal schemes of high-yield of ＇Jihua 1＇ （higher than 3 300.00 kg/ha） was： the density was 132.92 k-137.67 k points/ha, the nitrogen application rate was 217.7-241.1 kg/ha, the phosphate application rate was 179.52-206.36 kg/ha, the potassium application rate was 191.68-210.68 kg/ha.
