摘要: 试验旨在研究热带假丝酵母(CT)、枯草芽孢杆菌(BS)、植物乳杆菌(LAP)、布氏乳杆菌(LAB)不同微生物添加剂组合对甘蔗尾青贮品质和有氧稳定性影响。本试验设置了10个组。对照组(C)不添加微生物添加剂;Ⅰ1、Ⅰ2、Ⅰ3组分别添加10、20和30 mL/kg的CT+BS菌液;Ⅱ1、Ⅱ2、Ⅱ3组分别添加10、20和30 mL/kg CT+BS+LAP菌液;Ⅲ1、Ⅲ2、Ⅲ3组分别添加10、20和30 mL/kg CT+BS+LAB菌液。添加0.5%尿素作为氮源。结果显示:①与对照组相比,CT+BS处理组pH、乙酸含量显著升高(P< 0.05),乳酸含量、干物质回收率(DMR)显著降低(P< 0.05),有氧稳定性有所降低;②与对照组相比,CT+BS+LAP处理组pH、乳酸含量显著升高(P< 0.05),且可降低青贮有氧稳定性;③与对照组相比,CT+BS+LAB处理组乙酸显著上升,DMR显著降低(P< 0.05),但粗蛋白质(CP)含量、有氧稳定性是所有处理组中最高的。因此,CT+BS处理青贮甘蔗尾品质较差,而CT+BS+LAB能改善甘蔗尾青贮品质,提高有氧稳定性。

Abstract: The assay was aimed to investigate the effect of different microbial inoculant combinations of Candida tropicalis (CT),Bacillus subtilis (BS),Lactobacillus plantarum (LAP) and Lactobacillus buchneri (LAB) on the quality and aerobic stability of sugarcane tops silage.There were 10 groups:Sugarcane tops silages with no additives served as control group (C);GroupsⅠ1,Ⅰ2 and Ⅰ3 were treated with CT+BS at 10,20 and 30 mL/kg,respectively;Groups Ⅱ1,Ⅱ2 and Ⅱ3 were treated with CT+BS+LAP at 10,20 and 30 mL/kg,respectively;Groups Ⅲ1,Ⅲ2 and Ⅲ3 were treated with CT+BS+LAB at 10,20 and 30 mL/kg,respectively.Each treatment was treated with 0.5% fresh forge urea.The results showed that:①Compared to control group,CT+BS treatment groups had significantly higher levels of pH and acetic acid (P< 0.05),dry matter recovery (DMR) and lactic acid content were significantly decreased (P< 0.05),and the aerobic stability was lower.②Compared to control group,CT+BS+LAP treatment groups had significantly higher levels of pH and lactic acid (P< 0.05),and the aerobic stability was lower.③In CT+BS+LAB treatment groups,the levels of acetic acid were significantly higher and DMR was significantly lower than control group (P< 0.05),and the CP content and aerobic stability were highest in all groups.So the quality of sugarcane tops silage was lower in CT+BS treatment groups and CT+BS+LAB treatment could improve the quality and aerobic stability of sugarcane tops silage.

Key words: sugarcane tops silage; microbial inoculant; silage quality; aerobic stability
