本试验旨在研究添加米糠和小麦麸对2个品种的马铃薯茎叶青贮品质的影响。采用2×6双因子设计,2个因子分别为马铃薯品种( A)和马铃薯茎叶与米糠、小麦麸的混合比例( B),其中马铃薯品种为庄薯3号( A1)和青薯169号( A2)；各混合比例为马铃薯茎叶单独青贮( B1)、85%马铃薯茎叶+15%米糠( B2)、81%马铃薯茎叶+15%米糠+4%小麦麸( B3)、77%马铃薯茎叶+15%米糠+8%小麦麸( B4)、73%马铃薯茎叶+15%米糠+12%小麦麸( B5)、69%马铃薯茎叶+15%米糠+16%小麦麸( B6)。共12个处理,每个处理4个重复。用600 mL玻璃瓶作青贮瓶。室温保存45 d。结果表明,与A1青贮饲料相比,A2青贮饲料有较高的感官评分及干物质、中性洗涤纤维含量(P<0.05),较低的pH及氨态氮、乳酸、丁酸、粗蛋白质含量(P<0.05)。与B1青贮饲料相比,B2青贮饲料有较低的pH及乙酸、丁酸、氨态氮、粗蛋白质含量和较高的乳酸、干物质、中性洗涤纤维含量及感官评分、乳酸/乙酸( P<0.05)。与B2青贮饲料相比,B3青贮饲料进一步降低了青贮饲料的pH及氨态氮、乙酸含量(P<0.05),提高了感官评分、乳酸/乙酸及乳酸、干物质、粗蛋白质、中性洗涤纤维含量。 B4、B5、B6青贮饲料又比B3青贮饲料有较低的氨态氮和丁酸含量(P<0.05),较高的干物质和粗蛋白质含量(P<0.05)。在感官评分、乳酸/乙酸及氨态氮、乳酸、丁酸、干物质含量和上,A、B两因子间存在互作( P<0.05)。对于相同比例的米糠和小麦麸,A2青贮饲料比A1青贮饲料更容易青贮成功。由此可见,在马铃薯茎叶中添加15%米糠和4%小麦麸即可获得良好的青贮品质。

This experiment was conducted to investigate the effects of adding wheat bran and rice bran on silage quality of 2 cultivars of potato vines. A 2×6 two factors experimental design was used. Potato vines (A) were from two potato cultivars: Zhuangshu 3 ( A1) and Qingshu 169 ( A2) . And six mixing ratios ( B) of wheat bran and rice bran were potato vines alone, ( B1 ) , 85% potato vines+15% rice bran ( B2 ) , 81% potato vines+15% rice bran+4% wheat bran ( B3) , 77% potato vines+15% rice bran+8% wheat bran ( B4) , 73%potato vines+15% rice bran+12% wheat bran ( B5 ) , 69% potato vines+15% rice bran+16% wheat bran ( B6) . There were 12 treatments with each treatment 4 replicates. Silages were prepared by using glass bottles ( 600 mL) in laboratory. The silos were kept at room temperature for 45 days. The results showed that A2 si-lage had higher sensory scoring and content of dry matter and neutral detergent fiber than A1 silage, and had lower pH and content of ammonia nitrogen, lactic acid, butyric acid and crude protein than A1 silage ( P<0.05) . Compared with B1 silage, B2 silage decreased pH and content of acetic acid, butyric acid, ammonia nitrogen and crude protein ( P<0.05) , increased sensory scoring, lactic/acetic acid and content of lactic acid, dry matter and neutral detergent fiber ( P<0.05) . Compared with B2 silage, B3 silage decreased pH and con-tent of ammonia nitrogen and acetic acid ( P<0.05) , increased sensory scoring, lactic/acetic acid and content of lactic acid, dry matter, crude protein and neutral detergent fiber ( P<0.05) . B4, B5, B6 silages had lower content of ammonia nitrogen and butyric acid and higher content of dry matter and crude protein than B3 silage ( P<0.05) . There were interactions between cultivar and mixing ratio on sensory scoring, lactic/acetic acid and content of ammonia nitrogen, lactic acid, butyric acid and dry matter ( P<0.05) . For the same mixing ratio, A2 silage had a better silage quality than A1 silage. It is concluded that potato vines can get good quality silages when mixing with 15% rice bran and 4% wheat bran.
