| Abstract: |
| 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. |
