摘要
采用三因素二次通用旋转组合设计,对豫南黄棕壤区油菜施用氮、磷、钾肥进行定量研究。建立了油菜目标产量函数模型;通过模型解析选优,确定了每公顷油菜目标产量≥2250kg;≥1875kg;≥1500kg及最高产量的施肥推荐措施。
Adopt two of factors in common use to rotate association design, at south of Henan Province yellow brown earth districts rape use nitrogen, potassium, phosphorus go on quantitative research. Have set up the function model of output of goal of rape; Through model being analytic to select excellent, determine each hectare of rape goal output ≥2250kg; ≥1875kg; ≥1500kg. And most high yield apply fertilizer measure of giving a recommendation.
