以油用向日葵品种陇葵杂2号为试验材料，研究了不同施肥处理下向日葵器官中氮磷钾的吸收积累变化，进一步分析了三要素间的相关关系。结果表明，苗期各处理根、茎中氮、磷含量最高，随生育期推进，其含量下降。根中钾素含量苗期到现蕾期下降，现蕾期到开花期其含量上升。叶片中钾素含量苗期到开花期上升，开花到成熟期有所降低。花盘中钾素含量苗期到成熟期增多，成熟期达最高。籽粒中氮素含量最高，全植株现蕾期氮素含量最高；开花期磷素、钾素含量最高。陇葵杂2号每形成100 kg籽粒，需N 6.79 kg、P2O51.65 kg、K2O 15.52 kg，氮、磷、钾平衡施肥比例为4.1∶1∶9.4。

In this experiment,taking sunflower Longkuiza 2 as experiment material,the authors studied the changes of ab-sorption and accumulated of N P and Kunder the treatments of different fertilization of sunflower plant and different organs. Further studied the relationship of N P and K. The result shows that the root、stem、leaf and flower disc have the highest N and P in seeding stage,with the growth promote It decrease. Kcontent decreased of root from Seedling to budding stage,and from bud to flowering stages of its content rise. The Kcontent increase of leaves from seedling to budding,and it decrease from bud of flowering stage. Kcontent increase of flower dic form seedling to maturity stage and it up to the maximum in maturity. It have highest N content in grain. It have highest N content in bud of full plant and it have highest P、Kin flowering period. In all the growth period the sun-flower variety Longkuiza 2 per 100 kg grains,requiring N 6.79 kg、P2O5 1.65 kg and K2O 15.52 kg,balanced fertilization proportion of nitrogen,phosphorus and postassium is 4.1∶1∶9.4.
