以陇葵杂2号为指示品种，研究了不同施肥条件下向日葵生育期植株干物质积累量与氮、磷、钾积累量间的平衡关系，结果表明，向日葵植株干物质的积累量与氮、磷、钾积累量之间，以及氮、磷、钾在植株中的积累量间均呈极显著的线性正相关。以施尿素225 kg/hm2、普通过磷酸钙150 kg/hm2、氯化钾150 kg/hm2处理的氮、磷、钾施用量配比合理，在该施肥条件下，氮（N）、磷（P2O5）、钾（K2O）平衡施肥比例为4.1：1：9.4。

In this experiment,taking sunflower longkuiza 2 as instruction variety,the authors studied the relation of balance assimilation of N,P and K and accumulation of dry matter under treatments of different fertilization . The result showed that it was very obvious linearity correlation among accumulation of N,P and K in plants,between accumulation of N,P and K and accumulation of dry matter . It was reasonable ratio Use Urea 225 kg/hm2、Superphosphate150 kg/hm2、KCl 150 kg/hm2 . Under this condition the balance of fertikier ratio of N:P2O5:K2O=4.1:1:9.4 .
