摘　　要：以冷蒿(Artemisia frigida)为原料,通过直接青贮和使用添加剂青贮,研究其青贮特性。研究结果表明:直接青贮冷蒿的p H值为5.20,感官品质达到优良等级,感官评分为16分;使用添加剂青贮冷蒿的p H值为5.22,感官质量尚好,感官评分为13分。直接青贮的乳酸和乙酸含量高于添加剂青贮,丙酸和丁酸占总酸的百分比、氨态氮占总氮的百分比低于添加添加剂青贮。通过费氏评分法的评价结果来看,直接青贮冷蒿为65分,质量良好,而使用添加剂青贮冷蒿为37分,青贮质量达到合格。综合感官性状和发酵品质的评定,结论为冷蒿可以采用青贮方式进行保存,且直接青贮的方法更好。Artemisia frigida was used as material to make silage without adding additive and make silage adding additive. The results showed that sensory evaluation of the silages were nice and good, the mark were 16 and 13 respectively in silage without adding additive and in silage adding additive .The pH value of silage without adding additive and silage adding additive were 5.20 and 5.22 respectively. The addition of the additive can＇t increase content of LA and AA. Content of BA and PA in silage without adding additive less than in the silage adding additive. The results of Flieg＇s evaluation showed that the silage without adding additive was an excellent silage, the silage adding additive was a bad silage. Comprehensive sensory evaluation and fermentation quality, we found that Artemisia scoparia can make silage, making Artemisiafrigida silage without adding additive was the best way.
