摘  要：
本试验旨在研究绿汁发酵液和木聚糖酶对稻草青贮品质的影响。在常规水分(MC1)稻草青贮和低水分(MC2)稻草青贮中均设对照(CON)组及添加2 mL/kg绿汁发酵液(FGJ)组、20 mg/kg木聚糖酶(XYL)组、2 mL/kg绿汁发酵液与20mg/kg木聚糖酶的复合(MIX)组,每个处理组重复3次。常温下贮存60d开封,测定青贮的发酵品质和化学成分。结果表明,MC1青贮中,与CON组相比,MIX组水分和酸性洗涤纤维(ADF)含量显著降低(P<0.05),FGJ、XYL、MIX组氨态氮(AN)含量极显著降低(P<0.01)、水溶性碳水化合物(WSC)含量显著或极显著增加(P<0.05;P<0.01),XYL、MIX组中性洗涤纤维(NDF)含量显著降低(P<0.05),FGJ组pH极显著降低(P<0.01);MC2青贮中,与CON组相比,FGJ组水分含量显著降低、水溶性碳水化合物含量及干物质回收率(DMR)显著增加(P<0.05),FGJ、MIX组氨态氮和中性洗涤纤维含量显著或极显著降低(P<0.05;P<0.01)、pH极显著降低(P<0.01),MIX组酸性洗涤纤维含量显著降低(P<0.05)。较MC1青贮,MC2青贮的pH和干物质回收率极显著增加(P<0.01),水溶性碳水化合物含量显著增加(P<0.05),氨态氮含量极显著降低(P<0.01)。综上所述,在常规水分和低水分稻草青贮中,3种添加剂均有显著的添加效果,以绿汁发酵液与木聚糖酶复合添加的效果最佳,且低水分稻草青贮的效果优于常规水分稻草青贮。

摘  要：
This study aimed to prove up the effects of fermented green juice and xylanase on quality of rice straw silage.A control group(CON)and three treatment groups which added 2 mL/kg fermented green juice(FGJ),20 mg/kg xylanase(XYL),compound them(2mL/kg FGJ+20mg/kg XYL,MIX)respectively and were both set up with conventional moisture(MC1)and low moisture(MC2)of rice straw silage.Each treatment was repeated 3times.The materials were ensiled at room temperature and opened 60 days later.The results showed that in the MC1 silages,compared with the CON group,the contents of moisture and ADF in the MIX group were significantly decreased(P<0.05),the content of AN in the FGJ、XYL and MIX groups was extremely significantly decreased(P<0.01),the content of WSC in the FGJ、XYL and MIX groups was significantly or extremely significantly increased(P<0.05;P<0.01),the content of NDF in the XYL and MIX groups was significantly decreased(P<0.05),the pH in the FGJ group was extremely significantly decreased(P<0.01).In the MC2 silages,compared with the CON group,the content of moisture in the FGJ group was significantly decreased(P<0.05),the content of WSC and DMR in the FGJ group were significantly increased(P<0.05),the contents of AN and NDF in the FGJ and MIX groups were significantly or extremely significantly decreased(P<0.05;P<0.01),the pH in the FGJ,XYL and MIX groups was extremely significantly decreased(P<0.01),the content of ADF in the MIX group was significantly decreased(P<0.05).Compared with the MC1,the pH and DMR in the MC2 were extremely significantly increased(P<0.01),the content of WSC in the MC2 was significantly increased(P<0.05),the content of AN was extremely significantly decreased(P<0.01).In conclusion,three additive had significant effect in the MC1 silages and MC2 silages,especially the effect of the mixed addition of FGJ and XYL was the best,and the MC2 silages had higher quality than the MC1 silages.
