【摘要】 系统报道了油菜优化测土配方施肥中的七大参数：每形成百公斤油菜籽所需养分量、土壤供氮量（校正函数）、目标产量、肥料利用率、磷钾肥激发效应、磷钾肥计算系数等。经田间试验和大面积示范推广，其准确度达９１．４％，具有较大的可靠性，可作为油菜测土施肥使用。更多还原

【Abstract】 This paper systematically deals with serven parameters to optimize the soiI testing and fer-tilizer recommendation for rape cuIture,ie, the amount of the nutrient needed by the produc-tion of per 100 kg rapeseeds, the amount of soil nitrogen supply(the corrected function),thetarget yield, the fertilizer utilization coefficient,the phospho- potash priming action,the cal-culation coefficient of phosphate and potassium fertilizer etc.Their accuracy is 91.4%,whichhas been proved in field tests and large area application. So the parameters are reliable and Canbe used in soiI testing and fertilizer recommendation for rape culture.更多还原
