摘要
以饲用苎麻和全株玉米为混合青贮原料,利用电子鼻技术对饲用苎麻与全株玉米按不同比例混合青贮时发酵饲料气味进行检测分析,并对其信号响应值进行主成分分析、线性判别分析、传感器区分贡献率分析及雷达图分析,可实现7种不同混合比例青贮发酵样品的良好区分。结果还表明,饲用苎麻与全株玉米按不同比例混合青贮时,全株玉米的添加量对最终青贮饲料的气味组成有重要影响。因此,选取青贮效果正常的样品作为参考对象,利用电子鼻检测技术可有望快速鉴别出待检样品是否青贮成功。
In this paper,the fodder ramie and whole-plant corn were chosen as the fermented materialsof mixture silage,the smell of silage after mixed fermentation by the fodder ramie and whole-plant corn with adifferent ratio was tested and analyzed with the help of electronic nose,and then the response values of thesensor signal were deeply analyzed by the means of principal component analysis(PCA),linear discriminantanalysis(LDA),sensors to distinguish the contribution analysis(LOADING)and radar map.The results showedthat according to the smell analysis by the use of electronic nose,the7silage investigated in this paper couldbe well differentiated.In addition,the results also showed that the additive amount of whole-plant corn had asignificant influence on the overall smell structure for the final silage.Consequently,when the silage which waswell fermented was chosen as the reference object,whether the detecting silage was well fermented or notcould be identified quickly by the use of electronic nose technology.
