合理施肥是寒旱生态区宽叶羌活获得高产优质高效的关键，通过分析氮磷钾不同用量及配比施肥对寒旱生态区宽叶羌活主要农艺性状、品质、经济效益的影响，为高产优质高效栽培提供科学依据。以宽叶羌活为研究对象，设计了5个氮磷钾不同用量及配比施肥处理，测定不同氮磷钾施肥条件下羌活主要农艺性状、产量、羌活醇和异欧前胡素含量。结果表明，氮磷钾不同施用量及配比对寒旱生态区宽叶羌活的产量、品质及经济纯收益均有较大影响，其中施肥量为N 300 kg/hm2、P2O5 300 kg/hm2、K2O 150 kg/hm2，配比为1∶1∶0.5时，各项农艺综合性状较优，羌活单根重(干品)和芦头径粗分别较不施肥处理增加56.72%、28.57%；羌活的干品产量最高，为8 800.0 kg/hm2，较不施肥处理显著增产55.29%；羌活醇和异欧前胡素含量较不施肥提高58.82%；经济效益较不施肥增加297 819.1元/hm2。综合主要性状和经济效益，氮磷钾不同用量及配比施肥中，施肥量为N 300 kg/hm2、P2O5 300 kg/hm2、K2O 150 kg/hm2(配比为1∶1∶0.5)时，宽叶羌活的效果最好。

Rational fertilization is the key to achieving high-yield, high-quality, and efficient cultivation of Notopterygium forbesii in cold and arid ecological regions. This study analyzed the effects of different amounts and proportion of nitrogen, phosphorus, and potassium on the main agronomic traits, quality, and economic benefits of Notopterygium forbesii, providing a scientific basis for high-yield, high-quality, and efficient cultivation of Notopterygium forbesii. Using Notopterygium forbesii as the research subject, five nitrogen, phosphorus and potassium fertilization treatments with different amounts and proportion were designed. The study measured the main agronomic traits, yield, and contents of notopterol and isoimperatorin under different fertilization conditions. Results showed that different amounts and proportion of nitrogen, phosphorus and potassium had significant impacts on the yield, quality, and net economic benefits of Notopterygium forbesii in cold and arid regions. When the fertilizer amounts were N 300 kg/ha, P2O5 300 kg/ha, and K2O 150 kg/ha, with a proportion of 1∶1∶0.5, the comprehensive agronomic traits were optimal. The single root weight(air-dried product basis) and stem diameter increased by 56.72% and 28.57%, respectively, compared to the no-fertilizer treatment. The air-dried product yield of Notopterygium forbesii reached a maximum of 8 800.0 kg/ha, a significant increase of 55.29% compared to the no-fertilizer treatment. The contents of notopterol and isoimperatorin were 58.82% higher, and economic benefits increased by 297 819.1 Yuan/ha. Based on the comprehensive agronomic traits and economic benefits, the best fertilization treatment for Notopterygium forbesii was N 300 kg/ha, P2O5 300 kg/ha, and K2O 150 kg/ha, with a proportion of 1∶1∶0.5.
