摘　　要：[目的]为了掌握各个施肥单元对食用向日葵的优化施肥数量以及基肥、追肥分配比例。[方法]2006~2009年临河区在食用向日葵上安排"3414"肥料效应试验,研究植物的营养过程,阐明各种肥料的效应、肥料之间的配合以及"土壤-肥料-作物"之间的相互作用。[结果]通过"3414"田间试验以及土壤测试,分析不同土壤肥力基础下土壤有效养分含量与食用向日葵相对产量的相关性,并依此确定土壤养分等级和最佳施肥量。[结论]该研究确定了一个合适的施肥养分配比,给广大农民开出优化、合理的配方。[ Objective] The research aimed to master optimized fertilization amount in each feltilization period on the edible sunflower and the allocation proportion of basic fertilizer and top application. [ Method ] ＂3414＂ fertilizer effect experiment was designed in Linhe district,2006- 2009. The nutrition course of the sunflower was studied. The effects of each fertilizer, the coordination of the fertilizers and the interaction of soil- fertilizer-crop were analyzed. [ Result] Soil available nutrient contents under different soil fertility and the con＇elation with the relative yield of the edible sunflower were an^yzed. Thus the grades of soil nutrition and the optimum fertilization amount were determined. [ Conclusion ] The optimum fertilization distribution ratio was determined, so as to draw the optimized and regular formula for peasants.
