摘  要：
为探求豫北中高肥力条件下水稻高产栽培施用N、P、K肥的最优参数,以水稻品种新丰7号为试验材料,采用回归设计方案,运用多元二次回归建模及非线性优化等方法,对试验结果进行建模、模拟及优化.结果表明:配比施肥比不施肥处理或缺素处理增产效果明显,缺氮或缺磷处理对产量的影响大于缺钾处理.通过对N、P、K全信息肥效模型及其二阶交互肥效模型模拟分析比较,得出中高肥力条件下水稻高产优化施肥决策为:施N193.05~206.25 kg/hm~2,P_2O_5 65.84~74.57 kg/hm~2,K_2O 94.71~110.07 kg/hm~2,优化施肥配比m(N)∶m(P_2O_5)∶m(K_2O)为1∶0.35∶0.51,产量期望9 658.83~9 808.46 kg/hm~2.配比施肥有利于水稻对养分的吸收利用,提高肥料利用率.

摘  要：
In order to achieve the goal of high yield and high efficiency cultivation by exploring the optimum parameters of N,P,K based on medium-high fertility in Northern Henan,using the rice variety Xinfeng 7 as the experimental material,the test was modeled,simulated and optimized by the way of regression design,multiple quadratic regression,nonlinear optimization.The results showed that the effect on yield by prescription fertilization was better than non-fertilizer or elements deficiency and the effect of nitrogen deficiency,phosphorus deficiency was worse than potassium deficiency.By comparing the N-P-K fertilizer effect model with two-order interaction fertilizer effect model,the optimal decision was got ∶N 193.05 ~206.25 kg/hm~2,P_2O_5 65.84 ~74.57 kg/hm~2,K_2O 94.71 ~110.07 kg/hm~2,optimized fertilization ratio ∶m(N)∶m(P_2O_5)∶m(K_2O)=1 ∶0.35 ∶0.51,expected production: 9 658.83 ~9 808.46 kg/hm~2.Prescription fertilization is good for absorbing nutrition and improving the effect of fertilizer.
