【摘要】 研究了长期贮藏及低含水量条件下裹包层数对苜蓿裹包青贮品质的影响。含水量50%的苜蓿采用2、4、6和反转2层裹包贮藏7个月;含水量50%、40%和20%的苜蓿采用4和6层裹包,贮藏2个月。结果表明:长期贮藏情况下,4、6和反转2层裹包的青贮品质无显著差异(P>0.05),优于2层裹包处理;不同含水量的所有裹包处理组均调制出高品质的青贮饲料,在同一含水量条件下,4与6层裹包的青贮品质无显著差异(P>0.05)。更多还原

【Abstract】 The present study was conducted to investigate the effects of wrapping layers(2、4、6,or 2+2) on the alfalfa silage quality.The results show that when the alfalfa moisture content was about 50% and the materials were fermented for 7months,the quality of the silage with 2 wrapping layers was impaired,while that of the others were maintained with no significant differences among them(P>0.05).It is also found that the alfalfa silage quality of different moisture content of 50%,40%,or 20%,with 4 or 6 wrapping layers remained guaranteed after 2 months fermentation,and that there was no significant difference between these two treatments with silage of similar moisture content(P>0.05).更多还原
