| 摘 要： | 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4.119.4.

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