添加剂对水葫芦青贮品质的影响

摘要/Abstract

摘要： 为探明不同添加剂对水葫芦青贮品质的影响，本试验设对照、添加绿汁发酵液、添加蔗糖、添加甲酸、添加四蚁酸铵、添加绿汁发酵液+蔗糖共计6个处理，调制了水葫芦青贮。每个处理作2次重复，在30℃下发酵40d开封，测定青贮的发酵品质和化学成分。5种添加剂均降低了青贮的pH、氨态氮和中性洗涤纤维（P<0.01，P<0.05）；除四蚁酸铵外的添加剂均提高了青贮的干物质回收率、降低了青贮的水分和酸性洗涤纤维（P<0.01，P<0.05）；除蔗糖外的添加剂均降低了青贮的气体损失率（P<0.01）；除绿汁发酵液外的添加剂均提高了青贮的水溶性碳水化合物含量（P<0.01）。结果表明，各种添加剂均不同程度地改善了青贮的品质，其中以添加绿汁发酵液+蔗糖的效果最佳

Abstract: This experiment is to study effects of different additives, in which the water hyacinth were ensiled by adding additives as following fermented green juice (FGJ), sucrose (SUC), formic acid (FA), foraform (FOR), fermented green juice plus sucrose (MIX) and without additives (control). Each treatment was two repeats. Ensilages were stored in incubators at 30℃, and ensilaged for 40 days, then measured the fermentation quality and chemical composition of silage. All the additives reduce the pH value, ammoniacal nitrogen and neutral detergent fiber of silage（P<0.01，P<0.05）. All the additives except FOR enhanced dry matter rate of silage while reduced moisture content and acid detergent fiber of silage（P<0.01，P<0.05）. And gas loss rate were reduced by all the additives except sucrose（P<0.01）. Besides, all the additives except fermented green juice increased water-soluble carbohydrate（P<0.01）. Results showed that all of the five additives could improve the quality of water hyacinth silages, and the MIX is the best.
