摘　　要：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,分别为按鲜草重加甲酸1.5,3.0,4.5g·kg-1,加甲醛1.5,3.0,4.5g·kg-1,加甲酸1.5g·kg-1+甲醛1.5g·kg-1,加甲酸3.0g·kg-1+尿素5.0g·kg-1,加甲醛3.0g·kg-1+尿素5.0g·kg-1。另设不加任何添加剂的对照。结果表明:甲酸可作为玉米秸青贮添加剂,添加量按鲜玉米秸3g·kg-1添加,亦可同时添加尿素5.0g·kg-1。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。Corn stalks had ensilaged in bag with additives for 9 treatments which were added formic acid 1.5, 3.0, 4.5 g·kg^-1, formaldehyde 1.5, 3.0, 4.5 g·kg^-1, formic acid 1.5 g·kg^-1＋ formaldehyde 1.5 g·kg^-1, formic acid 1.5 g·kg^-1＋ urea 5.0 g·kg^-1, formaldehyde 1.5 g·kg^-1＋urea 5.0 g·kg^-1, respectively. There, were two controls that were no addictives and be added 100 g·kg^-1 water. The resuits indicated that formic acid can be used as silage additives in the dose the 3.0 g·kg^-1, and urea can he also added in the dose of 5.0 g·kg^-1. Formaldehyde can＇t be used to treat corn stalks. Urea or formic acid can＇t be incorporated with formaldehyde.
