摘要
本研究设计了4种混合比例的水葫芦玉米秸秆混合青贮,即水葫芦∶玉米秸秆按鲜重比为8∶2,7∶3,6∶4和5∶5(略为W8M2、W7M3、W6M4和W5M5),探讨生物添加剂绿汁发酵液(FGJ)、纤维素酶(CEL)和绿汁发酵液+纤维素酶(MIX)的效果。每个处理3次重复,常温下贮存60d,开封后评定其青贮品质。结果表明,3种添加剂对不同混合比例的材料均能显著(P<0.05)提高其青贮品质,特别是绿汁发酵液和纤维素酶的混合添加,具有相乘作用,效果更好。随着玉米秸秆混合比例的升高,青贮品质提高,W5M5的效果最好。
In order to investigate the effects of biological additives on the quality of mixing water hyacinth and maize stalk,four mixture ratios of water hyacinth and maize stalk at 8∶2,7∶3,6∶4 and 5∶5(W8M2,W7M3,W6M4 and W5M5) were designed.In addition,no-additive,fermented green juice(FGJ),cellulase(CEL) and FGJ+CEL(MIX) were added for all materials.After ensiled for 60 days at ambient temperature,the nutritional composition were measured for each treatment.Three kinds of additives significant improved the fermentation quality of water hyacinth and maize straw mixed silages(P0.05).FGJ and CEL also had obvious interaction.In addition,with the increase of corn straw mixture ratio,the quality of silage was improved.W5M5 was the best silage.
