为丰富天水中药材种植种类，从湖北黄冈引进蕲艾品种，以天水艾草为对照开展品种比较试验。结果表明，九尖蕲艾在生物学特征、产量、茎叶比、有效成分含量等方面表现均优于天水艾草，其平均株高为161.5 cm，平均株幅为24.8 cm，裂片数5片，叶色深绿。鲜重产量29 571.4 kg/hm2，较对照品种天水艾草增产290.6%；干重产量12 809.5 kg/hm2，较对照品种天水艾草增产273.6%。茎叶比0.86。经陇西数字本草检测中心检测，九尖蕲艾桉油精含量3.39 mg/g、龙脑1.12 mg/g、总灰分102 g/kg、酸不溶性灰分19 g/kg ；其中主要成分桉油精、龙脑含量均超过《中国药典》桉油精不得少于0.50 mg/g 、龙脑不得少于0.20 mg/g 的标准。九尖蕲艾植株高大、茎叶比小、产量高、药效成分高，适宜于天水地区种植。

To enrich the Chinese herbal plant varieties in Tianshui, a series of varieties of Artemisia argyi were introduced from Huanggang, Hubei Province and were used to carry out a variety comparison test with the wild wormwood in Tianshui. The results showed that Jiujian Artemisia argyi was superior to Tianshui's wild wormwood in biological characteristics, yield, ratio of stem to leaf, and content of effective components. Its average plant height was 161.5 cm, average plant width was 24.8 cm, number of lobes was 5, and its leaves were dark green. The average yield of fresh weight was 29 571.4 kg/ha, which was 290.6% higher than that of the control Tianshui wild wormwood. The average dry weight yield was 12 809.5 kg/ha and was 273.6% higher than that of the control. The stem to leaf ratio was 0.86. The contents of eucalyptus olein, borneol, total ash and acid insoluble ash were 3.39 mg/g, 1.12 mg/g, 102 g/kg and 19 g/kg, respectively, determined by Longxi Digital Herbal Testing Center. The contents of eucalyptus olein and borneol exceeded the standard of Chinese Pharmacopoeia which indicated eucalyptus olein content should be no less than 0.50 mg/g and borneol content should be no less than 0.20 mg/g. Jiujian Artemisia argyi is suitable for planting in Tianshui because of its tall plant height, low stem to leaf ratio, high yield and high contents of effective components. 参考文献: [1] 刘先华，周 安，刘碧山，等. 艾叶挥发油体内外抑菌作用的实验研究[J]. 中国中医药信息杂志，2006，13(8):25-26.
