| 摘 要： | 利用"3414"肥料效应试验,研究了花生氮磷钾肥料效应及其合理施用量。结果表明:最佳经济产量,一元二次方程、二元二次方程略低于三元二次方程(-3.2%、-2.3%);最佳经济产量施肥量,一元二次方程、二元二次方程明显低于三元二次方程(-12.0%、-13.2%);产投比,一元二次方程、二元二次方程均高于三元二次方程(9.3%、12.5%)。可以采用3类7种效应函数求解得到的氮、磷、钾最佳经济产量施肥量的平均值作为推荐施肥量:即氮(N)134.7 kg/hm~2、磷(P2O5)210.4 kg/hm~2、钾(K2O)172.0 kg/hm~2。可获得最佳经济产量6307.4 kg/hm~2,产投比为14.02。NPK互作效应最高,其次是NP、NK,PK互作效应最低。

| Abstract: | Abstract: The paper studies on the peanut NPK fertilizer effect and its rational application rate through the "3414" test. The results showed that in the optimum economic output, a quadratic equation and binary quadratic equation were slightly lower (-3.2%, - 2.3%) than ternary quadratic equation; in the optimum application rate of economic output, a quadratic equation and binary quadratic equation were apparently lower (-12.0%, - 13.2%) than ternary quadratic equation; in the output-input ratio, a quadratic equation and binary quadratic equation were higher (9.3%, 12.5%) than ternary quadratic. Therefore, the best application rate is the average of the optimum application rate of economic output of nitrogen, phosphorus, and potassium solved from effect function of seven categories and three kinds: nitrogen (N) 134.7 kg / hm2, phosphorus (P2O5) 210.4kg / hm2, potassium (K2O) 172.0kg / hm2. The optimum economic output is 6307.4kg / hm2, and the output-input ratio is 14.02. The interaction effect, in turn from maximum to minimum, is NPK, NP, NK, and PK. |
