为了展示当归绿色高效施肥技术，2021年在岷县中药材绿色种植基地开展示范性试验。试验设7个不同施肥处理，研究不同施肥模式对当归形态特征、产量、收益及有效成分的影响。结果表明，较常规施肥[复混肥料(总养分≥45%， N-P2O5-K2O为20-15-10)750 kg/hm2、 磷酸二铵300 kg/hm2、 有机肥(有机质≥45%， N+P2O5+K2O≥5%)1 200 kg/hm2]而言，6种施肥模式当归芦头径增加0.14～0.40 cm、根长增长0.16～3.03 cm、主根径增加0.15～0.34 cm、单根鲜重增加10.67～26.16 g/株；当归产量增加333.90～1 740.90 kg/hm2，产量增幅为2.69%～14.03%，较常规施肥增收3 665～15 159 元/hm2。阿魏酸含量增加了0.014～0.020 百分点，挥发油含量增加了0.07～0.14 百分点，醇浸出物含量增加了0.8～2.9百分点。6种模式对当归根部形态特征、产量、收益、有效成分等均有正效应。

In order to further strengthen the application of green and efficient fertilization technology for Chinese angelica root, demonstration experiment was carried out at the Green Planting Base of Chinese Medicinal Materials at Min countyin 2021, 7 different fertilization treatments were conducted to study the effects of different fertilization modes on the morphological characteristics, yield, economic return and contents of active ingredients of Chinese angelica root. Results showed that compared with conventional fertilization mode, which was compound fertilizer 750 kg/ha(total nutricents≥45％, N-P2O5-K2O, 20-15-10) plus diammonium phosphate 300 kg/ha plus organic fertilizer 1 200 kg/ha (organic content≥45%, N-P2O5-K2O≥5%), the diameter of Lutou was increased by 0.14 to 0.40 cm, the root length was increased by 0.16 to 3.03 cm, the main root diameter was increased by 0.15 to 0.34 cm, and the fresh weight of a single root was increased by 10.67 to 26.16 g/plantin other 6 fertilization modes. The yield was increased by 333.90 to 1 740.90 kg/ha, the yield increasing was 2.69% to 14.03% and income increasing in other 6 modes was 3 665 to 15 159 RMB/ha compared with that of the conventional fertilization mode. Furthermore, the ferulic acid content was increased by 0.014 to 0.020 percentage points, the volatile oil content was increased by 0.07 to 0.14 percentage points, the alcohol extract content wasincreased by 0.8 to 2.9 percentage points. Overall, other 6 fertilization showed positive effects on morphological characteristics, yield, economic returnand contents of active ingredients of Chinese angelica root.
