摘要： 以绿狐尾藻作为研究材料，探讨添加Lactococcus lactis (LL)，Lactobacillus plantarum (LP)和复合菌剂(FH)对绿狐尾藻青贮品质的影响。试验设4 个处理组，即对照组(CK)、actococcus lactis 菌剂组(LL)、Lactobacillus plantarum 菌剂组(LP)、Lactococcus lactis 和Lactobacillus plantarum 复合菌剂组(FH)；在青贮第1、3、7、15、30 天取样，实验室分析干物质含量、pH值、粗蛋白含量、中性洗涤纤维、酸性洗涤纤维及有机酸含量。研究结果表明：与对照相比，LL菌剂组可以显著降低绿狐尾藻青贮的pH值(P<0.05)，提高乳酸含量(P<0.05)，较对照组增加了131.2%；中性洗涤纤维含量显著低于对照组(P<0.05)，与对照组相比降低了17.23%；酸性洗涤纤维的含量相比对照组显著降低(P<0.05)，比对照组降低了24.56%。FH菌剂组的粗蛋白含量显著高于对照组(P<0.05)，较对照组高出12.6%。综上所述，乳酸菌菌剂可以改善绿狐尾藻的青贮品质、营养价值以及消化利用率，为绿狐尾藻的资源化利用提供了数据基础支撑。

Abstract: [Objective]In order to investigate the effects of different silage inoculants on silage quality of Myriophyllum quaticum, this study was based on the Myriophyllum quaticum and Lactococcus lactis (LL), Lactobacillus plantarum(LP) inoculants. [Method]The treatments were control (without additives), LL, LP, and FH(LL+LP) . The samples were taken on 1,3,7,15 and 30 days after ensiling and the nutritional composition and the silage quality were analysed in the laboratory. [Result]The results showed that : compared with the control, the pH value of the LL treatment decreased significantly(P<0.05), and the neutral detergent fiber content had a decrease of 17.23% ,while the lactic acid content was increased significantly(P<0.05),with an increase of 131.2%.The acid detergent fiber content of the LL treatment decreased by 24.56%(P<0.05).And the crude protein content of the FH treatment was increased by 12.6% (P<0.05). [Conclusion]In conclusion, the Lactic acid bacteria (LAB) inoculants could improve the silage quality, the nutritional value and the digestibility of Myriophyllum quaticum silage which provided a data basis for the resource utilization of the Myriophyllum quaticum.
