在甘肃省当归主产区岷县、漳县、渭源县，研究了含腐植酸高塔熔体当归专用肥与常规施肥对当归根部形态特征、产量和品质的影响。结果表明，在减少纯养分投入132 kg/hm2的条件下，施用含腐植酸高塔熔体当归专用肥较常规施肥的可使当归干芦头径增加7.73%～8.29%、干主身径增加15.52%～24.82%、干根长增加10.43%～14.25%、干根重增加8.17%～16.06%、产量增加12.56%～18.05%、阿魏酸含量增加0.007～0.014百分点、挥发油含量增加0.07～0.14百分点、醇浸出物含量增加0.5～2.2百分点、净经济效益增加21 627～28 646元/hm2。

The effects of special fertilizer and conventional fertilization on morphological characteristics， yield and quality of Angelica sinensis root were studied in Minxian， Zhangxian and Weiyuan countyof Gansuprovince. The results showed that under the condition of reducing pure nutrient input by 132 kg/hm2， compared with conventional fertilization， the application of special fertilizer for Angelica sinensis with high-tower melt containing humic acid could increase the diameter of dry asparagus by 7.73% ～ 8.29%， the diameter of dry main body by 15.52% ～ 24.82%， the length of dry root by 10.43% ～ 14.25%， theweight of dry root by 8.17%～ 16.06%， the yield by 12.56%～8.05%， the content of ferulic acid by 0.007～0.014 percentage points， the content of volatile oil by 0.07～0.14 percentage points， the content of ethanol extract by 0.5～ 2.2 percentage points， and the net economic benefit increasedby 21 627～28 646 yuan/hm2.
