| 摘 要： | 初花期收获的苜蓿经过0,8和32 h的晾晒,添加乳酸菌和纤维素酶进行青贮。结果表明,不同干物质含量的苜蓿青贮时,乳酸菌 纤维素酶的添加均能使青贮pH值快速下降;苜蓿半干青贮(干物质含量为38.45%)可使青贮氨态氮含量显著降低,并保存有较多的粗蛋白质,生成较多乳酸,其中以添加乳酸菌106cfu/g 纤维素酶0.05g/kg的青贮效果最好,其青贮综合评定得分最高,达93分。 |
| 关 键 词： | 苜蓿 乳酸菌 纤维素酶 青贮品质 |

| Abstract: | Medicago sativa was harvested at the initial flowering stage and wilted for 0,8 or 32 h after which the DM contents were 27.15%,38.45% and 50.87%,respectively.It was ensiled with lactic acid bacteria cellulase at rates of 105 cfu/g 0.100 g/kg,106 cfu/g 0.050 g/kg and 107 cfu/g 0.025 g/kg.All additions rapidly decreased silage pH under different DM contents of M.sativa.M.sativa(DM 38.45%) ensiled with lactic acid bacteria cellulase gave the best results: ammonia nitrogen content was reduced,and most CP was conserved and most lactic acid produced.The silage points of M.sativa(DM 38.45%) with the addition of 106 cfu/g lactic acid bacteria and 0.050 g/kg cellulase was 93 and its silage quality was better than those of other treatments. |
