摘　　要：为研究探讨新乡市高产水稻优化配方施肥量,采用3415最优回归设计田间试验测得的数据,建立了以产量为目标函数的N、P、K三元二次回归模型与NP、NK、PK的二元二次回归模型及N、P、K单因素效应模型,通过模拟因素取值的频率分析,决选出各自模型的优化施肥量及产量期望,进而通过3类7种模型提供的施肥决策和相应产量期望的经济效益分析比较,筛选出NP二元二次回归模型(K2O固定于"2"水平),即施N 186.59 kg/hm2,P2O592.25 kg/hm2,K2O 120.00 kg/hm2,既可获得10 335.32 kg/hm2产量,又能获取产投比为23.39的最大经济效益,可作为新乡市高产水稻的推荐施肥量.根据产量结构模型,模拟出不同高产水平下的产量结构,明确了高产栽培的主攻目标.To investigate the high-yielding rice optimization formula fertilizer in Xinxiang,using the data of regression design field test by ＂3415＂ program.The models were established that N,P,K ternary quadratic regression model,NP, NK,PK binary quadratic regression model and N,P,K single factor effect model,which take yield as the objective function.The optimization fertilizer and yield expectations of each model were reached by simulating factors value.By comparison fertilizer,expecting yield and economic benefits corresponding of each models,the NP binary quadratic regression model （K20 fixed to ＂2＂ level） was determined as the optimal fertilization model,i.e.fertilize N 186.59 kg/hm^2,P2O5 92.25 kg/hm^2,K2O 120.00 kg/hm^2,which can achieve race yield 10 335.32 kg/hm：,but also obtaining maximum economic benefit of output-input ratio 23.39.It can be used as the high-yield rice recommendation fertilizer in Xinxiang City.According yield structural model,the yield structures under different levels of high-yield were simulated,and the main target of high-yield cultivation was quite explicit.
