摘　　要：采取田间小区试验,研究氮磷钾配施对夏阳白肥料利用率及产量的影响,探索夏阳白对NPK肥料的利用效率,以期为夏阳白科学施肥提供科技支撑。结果表明,N肥对夏阳白生物产量、经济产量影响最大,K肥次之、P肥第三,N、P、K肥料配合施用能显著提高肥料利用率,是提高夏阳白产量的关键措施。A field plot experiment was conducted to study the effect of combined application of nitrogen, phosphorus and potassium on fertilizer utilization efficiency and yield of Xiayangbai, and to explore the utilization efficiency of NPK fertilizer, so as to provide scientific and technological support for scientific fertilization of Xiayangbai. The results showed that N fertilizer had the greatest effect on the biological yield and economic yield of Xiayangbai, followed by K fertilizer, P fertilizer. The combined application of N, P and K fertilizer could significantly improve the fertilizer use efficiency, which was the key measure to improve the yield of Xiayangbai.
