绿汁发酵液和纤维素酶对稻草青贮及稻草、甘蔗梢混合青贮品质的影响
Effects of Fermented Green Juice and Cellulase on the Fermentation Quality of Rice Straw Silage and Rice Straw with Sugarcane Tip Mixed Silage
摘要
Abstract
Rice straw and sugarcane tip were used as the silage materials in this research,and there were two groups:Rice straw silage and mixed silage of rice straw and sugarcane tip with the mixed ratio 6 ∶ 4(m/m).Four treatment groups were set up in each silage:Control group (CON) and three treatment groups which added 2 mL/kg fermented green juice (FGJ),3 mL/kg cellulase (CEL) and 2 mL/kg FGJ+3 mL/kg CEL (MIX),and treatment was repeated 3 times.The materials were ensiled at room temperature for 60 days,and the fermentation quality and chemical compositions were tested.The result showed that for the two kinds of raw silage materials,the contents of WSC and CP in rice straw were lower than those in sugarcane tip,while the contents of NDF and ADF in rice straw were higher than those of sugarcane tip.Compared with the CON group,the NDF,ADF,pH and NH3-N in FGJ group were extremely significantly decreased when rice straw was silaged alone (P＜0.01),while WSC was extremely significantly increased (P＜0.01),and DMR was increased.The NDF,ADF,pH,GLR and NH3-N in MIX group were extremely significantly decreased (P＜0.01),while lactic acid,WSC and DMR were increased.In CEL group,the ADF was significantly decreased (P＜0.05),and other indicators also had improved in different degrees.Compared with rice straw silage,the NDF,HC,pH and NH3-N of mixed silage were lower,while DMR and WSC were obviously increased.In conclusion,the fermented green juice and it compound with cellulase had the similar effects on improving the fermentation quality,and the effects were both better than that of cellulase.The fermentation quality of rice straw with sugarcane tip mixed silage was better than rice straw silage.关键词
