摘　　要：本试验通过袋贮玉米秸进行添加剂种类筛选和用量研究。试验设立9个处理，分别为按鲜草重量加甲酸1．5、3．0、4．5g／kg，加甲醛1．5、3．0、4．5g／kg，加甲酸3．Og／kg＋尿素5．0g／kg，加甲醛3．0g／kg＋尿素5．0g／kg，加甲酸1．5g／kg＋甲醛1．5g/kg。另设不加任何添加剂的对照。结果表明：玉米秸青贮甲酸可作为添加剂，按每千克鲜玉米秸添加3g，亦可同时添加尿素5．0g/kg。玉米秸青贮不宜添加甲醛。尿素与甲醛、甲酸与甲醛也不宜同时添加。Maize stalks had been ensilaged in bag with additives for 9 treatments which include formic acid 1.5, 3.0, 4.5g/kg, formaldehyde 1.5, 3.0, 4.5g/kg, formic acid 3.0g/kg ＋ urea 5.0g/kg, formaldehyde 3.0g/kg ＋ urea 5.0g/kg, formaldehyde 1.5g/kg ＋ formic acid 1.5g/kg. The contrast group don＇t add any additive. The results indicated： formic acid can be used as silage additives in the dose of 3g/kg · FM. And urea can be also added in the dose of 5 g/kg · FM. Formaldehyde can＇t be used to treat maize stalks. Urea or formic acid can＇t be added together with formaldehyde.
