摘要：

为开发利用水葫芦生产优质青贮，本研究制作了水葫芦单贮和5种水葫芦玉米秸秆混合青贮（混贮），5种混贮的水葫芦︰玉米秸秆（质量比）分别为80︰20、70︰30、60︰40、50︰50和40︰60（简称为80︰20混贮等），并在单贮和各种混贮中设对照（CON）组、添加玉米秸秆绿汁发酵液（FGJC）组、添加水葫芦绿汁发酵液（FGJW）组、添加蚁酸（FA）组和添加四蚁酸铵（FOR）组。每个处理作2次重复，常温下贮存60d，开封后测定青贮的pH、干物质回收率（DMR）、气体损失率（GLR）、氨态氮（NH3-N）等指标。结果表明，4种添加剂在所有青贮中都有一定的添加效果，其中，FGJC组和FGJW组在80︰20混贮中的添加效果最佳；混贮的品质均优于单贮。调制水葫芦玉米秸秆混贮是开发利用水葫芦的一条极佳途径。

Abstract:

For the purpose of producing high quality silage, water hyacinth silage and water hyacinth & corn straw mixed silage were studied. Water hyacinth & corn straw were mixed into 5 silages with their weight ratio of 80:20, 70:30, 60:40, 50:50 and 40:60, besides water hyacinth silage. Water hyacinth silage and mixed silage with CON，corn straw fermented green juice (FGJC)，water hyacinth fermented green juice (FGJW)，formic acid (FA)，foraform (FOR) were ensiled to study the effect of the additives. Each treatment was two repeats. Silages were fermented for 60 days under normal temperature. Then the pH value, dry matter rate（DMR）, gas loss rate（GLR）, ammonia nitrogen（NH3-N）, and other items were measured. The result showed that the four additives significantly affected the fermentation quality of silages. The effect of FGJC and FGJW to the mixed silages with 80:20 mixed ratio was the best. The fermentation quality of mixed silages with additives was better than water hyacinth silages. Preparing of water hyacinth & corn straw mixed silages is a good way to utilize water hyacinth.
