水稻“3414”肥料效应田间试验报告

A field experiment report on rice "3414" fertilizer effect

通过"3414"水稻肥效试验结果,获得肥料效应函数方程,由此数学模型得出理论氮、磷、钾最佳施肥量。三元二次方程得出的最佳施肥量为:N:9.78kg/667m2、P2O5:1.55kg/667m2、K2O:5.25kg/667m2,最佳产量538.97kg/667m2。一元二次方程得出:N:9.13kg/667m2,最佳产量551.19kg/667m2;P2O5:2.64kg/667m2,最佳产量552.13kg/667m2;K2O:6.11kg/667m2,最佳产量530.88kg/667m2。结合当地农业生产实际,氮、磷、钾建议施用量分别为:N:9.5kg/667m2、P2O5:2.5kg/667m2、K2O:6.0kg/667m2。

By means of the results of fertilizer effect experiment,a functional equation was gained from the math model and the best N,P,K fertilization was coming from this model.The best fertilization from ternary quadratic equation：N：9.78kg/667m^2、P2O5：1.55kg/667m^2、K2O：5.25kg/667m^2,highest yield of 538.97kg/667m^2;from quadratic equation：9.13kg/667m^2 with highest yield of 551.19kg;P2O5：2.64kg/667m^2with highest yield of 552.13kg;K2O：6.11kg/667m^2with highest yield of 530.88kg.According to local conditions,the recommended fertilization are respectively N：9.5kg/667m^2、P2O5： 2.5kg/667m^2、K2O：6.0kg/667m^2.
