| 摘 要： | 本试验旨在研究绿汁发酵液和纤维素酶对香蕉茎+小麦麸混合青贮发酵品质的影响。调制1个香蕉茎单贮(BSS)组和8个香蕉茎小麦麸混合青贮组,分别为1个对照(CON)组,添加2 mL/kg绿汁发酵液(FGJ)组,添加0.05、0.15和0.25 g/kg纤维素酶(CEL1、CEL2和CEL3)3个水平组,添加FGJ+CEL1(MIX1)、FGJ+CEL2(MIX2)和FGJ+CEL3(MIX3)3个混合组,每组均设3个重复。常温发酵60 d,测定青贮的发酵品质和化学成分。结果表明,与BSS组相比,CON组的气体损失率(GLR)和pH显著降低(P<0.05)。与CON组相比,各添加剂组的干物质(DM)、干物质回收率(DMR)和可溶性碳水化合物(WSC)含量有不同程度的增高,中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)及氨态氮(AN)含量有不同程度的降低;与FGJ组相比,CEL和MIX组的DMR极显著升高(P<0.01)。在CEL组中,随CEL水平的增加,青贮效果愈好;与MIX1组相比,MIX3组的NDF含量显著减少(P<0.05),DMR显著升高(P<0.05);与CEL组相比,对应的MIX组有不同程度的改善。综上所述,在香蕉茎青贮中添加小麦麸有利于改善青贮品质,添加纤维素的效果优于添加绿汁发酵液的效果,二者混合效果更好,且混合后的青贮效果随着纤维素酶的增加而更好。

| Abstract: | This study produced banana stem single storage and the wheat bran mixed silage to research on the effect of fermented green juice and cellulase on the ensiling quality of banana stem and wheat bran mixed silage.There were a banana stem single silage group (BSS) and 8 banana stem wheat bran mixed silage groups.They were a control group,added 2 mL/kg fermented green juice (FGJ) group,added three levels (0.05,0.15 and 0.25 g/kg) of cellulose (CEL1,CEL2 and CEL3) groups,respectively,added three mixed (MIX1:FGJ+CEL1,MIX2:FGJ+CEL2,MIX3:FGJ+CEL3) groups.Each treatment was repeated 3 times.The materials were ensiled at room temperature and opened 60 days later.The fermentation quality and the chemical composition were analyzed.The results showed that compared with the BSS group,the GLR and pH of the CON group were significantly reduced (P<0.05).Compared with the CON group,the DM,DMR and WSC of the additive groups had different degrees of increase,the NDF,ADF and AN of them were reduced.Compared with the FGJ group,the DMR of the CEL groups and the MIX groups was extremely significantly increased (P<0.01).In the CEL groups,the fermentation quality was more and more better with the increase of the CEL level.Compared with the MIX1 group,the NDF content of the MIX3 group was significantly reduced (P<0.05),but the DMR was significantly increased (P<0.05).Compared with the CEL group,the corresponding MIX groups had different degrees of improvement.In conclusion,adding wheat bran in the banana stem silage was conductive to improve the fermentation quality.The effect of adding cellulose was better than the effect of adding fermented green juice,and the effect of mixed them was the best.The fermentation quality of mixed them was better with the increase of cellulase. |
