Effect of Different Planting Density and Amount of N, P, K Fertilizer on Yield of ‘Jihua 1' Peanut

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/hm²目标产量的优化栽培方案为:种植密度13.292万¹3.767万穴/hm²;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（K₂O）量每公顷应达到191.68～210.68 kg。

Abstract:

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 Jihua1 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.
