摘　　要：试验对苜蓿草渣直接青贮及苜蓿草渣与小麦秸不同比例(8.0∶2.0、7.5∶2.5、7.0∶3.0和6.5∶3.5)混贮效果、最佳配比进行了研究。结果显示:小麦秸与苜蓿草渣混贮的乳酸含量显著高于苜蓿草渣直接青贮(P<0.05),pH值、乙酸含量显著低于直接青贮(P<0.05),添加小麦秸可以改善苜蓿草渣青贮饲料的发酵品质;试验表明,苜蓿草渣与小麦秸按6.5∶3.5混贮时pH值显著低于其他处理(P<0.05),乳酸含量高于其他处理,Flieg评价得分最高,为优等饲料,苜蓿草渣与小麦秸混贮的最佳配比为6.5∶3.5。The direct silage of alfalfa fibrous residues and mixed silage quality of different rate（8.0：2.0,7.5：2.5,7.0： 3.0 and 6.5：3.5）between alfalfa fibrous residues （AFR）and wheat straw,and the ideal adding amount of the wheat straw were studied.The result indicated that the lactic acid content of the mixed silage were higher （P 〈 0.05）,and the pH and acetic acid content were lower （P 〈 0.05） than the directly AFR silage,the fermentation qualities were improved;in this experiment,when the rate was 6.5：3.5, the pH was lower （P 〈 0.05） and the lactic acid, total acid contents,and the Flieg score were higher than the others.The ideal rate of AFR and wheat straw was 6.5：3.5.
