摘　　要：本试验以杂交构树为研究对象,探讨糖蜜、酶菌复合制剂以及防腐剂对杂交构树青贮发酵品质的影响,为新型木本饲料资源的开发利用提供技术参考。试验分为5个组,分别为对照组(无添加)、添加霉菌复合制剂组(M组)、添加糖蜜组(TM组)、添加霉菌复合制剂+糖蜜组(MTM组)以及添加防腐剂组(FFJ组),每组3个重复。发酵60 d。结果表明:1)与对照组相比,各添加剂组的pH均显著降低(P<0.05),乳酸含量显著提高(P<0.05),不同程度地提高了发酵品质。2)与对照组相比,M组、MTM组及FFJ组均显著降低了氨态氮/总氮(P<0.05),其中FFJ组的干物质含量显著高于其他各组(P<0.05),而pH和氨态氮/总氮显著低于其他各组(P <0.05)。3)与对照组相比,M组及M TM组的酸性洗涤纤维含量显著降低(P<0.05)。综上,在杂交构树青贮中添加糖蜜、酶菌复合制剂及防腐剂,在发酵品质和营养价值方面均有明显的改善,其中MTM组和FFJ组具有较低的pH,能更好地保存粗蛋白质和干物质,FFJ组效果最好,但M TM组成本更低些。The hybrid paper mulberry was used as a research object,and this study was to investigate the effects of molasses,composite enzyme bacteria and preservatives on the fermentation quality of hybrid paper mulberry silage.There were 5 groups：control group（CK group）,composite enzyme bacteria group（M group）,molasses group（TM group）,composite enzyme bacteria group＋ molasses group（M TM group） and preservatives group（FFJ group）,with 3 repetitions in each group.Fermentation lasted for 60 d.The results showed as follow s：1） compared with the control,the pH in additive groups significantly decreased（P〈0.05）,whereas the content of lactate acid increased significantly（P〈0.05）.2） Compared with the control,the ammonia nitrogen/total nitrogen content in groups M,M TM and FFJ significantly decreased（P〈0.05）.The dry matter content in FFJ group was significantly higher than that in other groups（P〈0.05）,whereas,the pH and ammonia nitrogen/total nitrogen were significantly lower than those in other groups（P〈0.05）.3）Compared with the control,the acid detergent fiber content in groups M and M TM decreased significantly（P〈0.05）.In conclusion,the application of molasses,composite enzyme bacteria and preservatives to the hybrid paper mulberry silage can improve the fermentation quality and nutritive value.Groups M TM and FFJ have low pH,good preservation of protein and dry matter,and FFJ group has the best results,but the M TM group has lower cost.
