Abstract: The harvested early bloom sweetclover was left to wilt for 0 hour, 8 hour,or 30 hours. The plants contained various amount of dry matter of 27.36%, 38.69%, or 44.98% separately. Each pile was ensiled with formic acid at a rate of 2.5 ml/kg, 4.0 ml/kg and 5.5 ml/kg respectively. Results from the experiments showed that haylage (DM44.98%) added with formic acid decreased its ammonia nitrogen and increased its WSC and CP content.For hay of different percentage of dry matter,the application of formic acid (4.0 ml/kg) exhibited a satisfactory effect on silage fermentation,preferably on hay containing 27.36% dry matter.

摘要： 在收获后经过0、8和30h晾晒的初花期草木樨(干物质含量分别为27.36%、38.69%和44.98%)原料中,加入甲酸(添加量为2.5、4.0和5.5ml/kg)进行青贮。结果表明,添加甲酸能使草木樨青贮料氨态氮含量降低,并保存较多的可溶性糖;添加甲酸4.0ml/kg对三个干物质水平草木樨青贮均有良好效果,但以干物质含量27.36%组效果最好。
