黄蒿的可青贮性研究

Studies on Silage of Artemisia Scoparia

以黄蒿为原料,通过添加采禾添加剂青贮和和直接青贮,探讨黄蒿的可青贮性。试验结果表明,直接青贮和添加剂青贮后感官性状的评分分别为16和17分,达到了优良等级。添加剂青贮后的pH值为4.26,直接青贮后的pH值为5.09,直接青贮乳酸和乙酸占总酸的百分比高于添加剂青贮,丁酸占总酸的百分比为添加剂青贮高于直接青贮,氨态氮占总氮的百分比表现为直接青贮高于添加剂青贮。通过费氏评分法的评价结果来看,直接青贮为87分,为优良青贮;而添加剂青贮为56分,为合格。综合感官性状、发酵品质,黄蒿可以采用青贮方式进行保存,对黄蒿青贮时采用直接青贮的方法更好。

Artemisia scoparia was used as material to make silage without adding additive and make silage adding additive. The results showed that sensory evaluation of the silages achieved excellent grade, and the score were 16 and 17 respectively. The pH value of silage without adding additive and with it were 5.09 and 4.26 respectively. The addition of the additive can＇t increase content of LA and AA. Content of PA in silage without adding additive was 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 qualified silage. By the comprehensive combination of sensory evaluation and fermentation quality, we found that artemisia scoparia can make silage, and making Artemisia ordosica silage without adding additive was the best way.
