中文摘要:
      为建立高效经济的当归生产模式，于2017—2019年在甘肃省渭源县设置5种作物茬口（T3：豌豆-小麦-当归，T2：豌豆-蒙古黄芪-当归，T3：豌豆-马铃薯-当归，T4：豌豆-休耕-当归，CK：豌豆-当归-当归）进行田间试验，秋季收获后测定不同茬口当归根、叶养分含量、根活性成分和产量，采用主成分分析法确定各指标权重值、隶属综合因子分析法确定5种茬口的综合评价指数。结果表明：T2处理有利于促进当归根、叶中氮、磷、钾吸收累积，根部氮、磷、钾含量较CK分别显著增加29.98%、32.96%、24.29%（P<0.05）、叶部氮、磷、钾含量较CK分别显著增加37.72%、42.08%、64.63%（P<0.05），且该茬口的当归产量、根的阿魏酸、浸出物含量较CK分别显著增加19.44%、17.37%、9.54%（P<0.05）。综合评价指数表现为T2(0.74)>T4(0.51)>T3(0.48)>CK(0.29)>T3(0.25)。综上可知，豌豆-蒙古黄芪-当归是高寒阴湿区当归高效经济生产的适宜模式。
英文摘要:
      The five crop stubbles (T3: Pisum sativum\|Triticum aestivum\|Angelica sinensis, T2: Pisum sativum\|Astragalus mongholicus\|Angelica sinensis, T3: Pisum sativum\|Solanum tuberosum\|Angelica sinensis, T4: Pisum sativum\|fallow\|Angelica sinensis, and CK: Pisum sativum\|Angelica sinensis\|Angelica sinensis）were set up in Zhanpo Village, Lianpeng Town, Weiyuan County, Gansu Province from 2017 and to 2019 in order to establish an efficient and economical production mode for Angelica sinensis. The content of root, leaf nutrients, extractive, ferulic acid and yield under five crop stubbles were determined after harvest in autumn. The weight value of each indicator was determined by principal component analysis, and the comprehensive evaluation index of five crop stubbles was determined by comprehensive factor analysis. The results showed that T2 stubble promoted absorption and accumulation of nitrogen, phosphorus and potassium in root and leaf, and nitrogen, phosphorus, and potassium in root. Under T2 stubble were significantly increased by 29.98%, 32.96% and 24.29% respectively, compared with CK (P<0.05). The nitrogen, phosphorus, and potassium in leave under T2 stubble were significantly increased by 37.72%, 42.08% and 64.63% respectively, compared with CK (P<0.05). The yield of Angelica sinensis, the content of ferulic acid and extractive in root under T2 stubble were significantly increased by 19.44%, 17.37% and 9.54% respectively, compared with CK (P<0.05). The comprehensive evaluation index sorted as T2(0.74)>T4(0.51)>T1 (0.48)>CK (0.29)>T3 (0.25). In conclusion, T2 stubble (Pisum sativum\|Astragalus mongholicus\|Angelica sinensis) was a suitable model for efficient and economic production of Angelica sinensis in chilling and humid region of high\|elevation area.
