摘　　要：以赣油杂8号和华油杂50饲用油菜为试验材料,设置赣油杂无添加(G)、赣油杂乳酸菌(GL)、华油杂无添加(H)和华油杂乳酸菌(HL)4个处理组,其中乳酸菌添加剂为乳酸片球菌、植物乳杆菌和布氏乳杆菌(1∶1∶1)混合制剂,青贮35 d后对各处理组进行取样,分析添加乳酸菌对饲用油菜青贮发酵品质的影响。结果表明:青贮35 d后,添加乳酸菌显著提高了饲用油菜青贮乳酸/乙酸、粗脂肪和水溶性碳水化合物含量,显著降低乙酸、丙酸、乙醇和氨态氮含量,但对乳酸和丁酸含量无显著影响。综上,饲用油菜自然青贮效果良好,添加乳酸菌剂能在一定程度上改善青贮发酵品质,在生产中推荐使用合适的乳酸菌剂。Ganyouza No.8 and Huayouza 50 forage rape were used as the experimental materials.There were 4 treatments including Ganyouza no addition group(G),Ganyouza lactic acid bacteria(LAB)treatment group(GL),Huayouza no addition group(H)and Huayouza LAB treatment group(HL).The LAB additive was a mixture of Pediococcus acidilactici,Lactobacillus plantarum and Lactobacillus brucei(1∶1∶1).The samples were analyzed after 35 days of ensiling,and the effects of adding lactic acid bacteria on the fermentation quality of forage rape silage were analyzed.The results showed that addition of LAB significantly increased the lactic acid/acetic acid ratio,ether extract and water-soluble carbohydrate contents,and significantly decreased acetic acid,propionic acid,ethanol and ammonia nitrogen contents,but had no significant effects on the contents of lactic acid and butyric acid.In conclusion,forage rape had a good fermentation quality of natural ensiling,and addition of LAB could further improve the fermentation quality of forage rape silage.It is recommended to use suitable LAB inoculants in production of forage rape silage.
