Abstract：To investigate the efects of mixing ratios and additives on the qualityof mixed silage of whole-plant corn（Zea mays） and forage triticale（Triticosecale Witmack），this study prepared silage with fresh weight ratios of 10：0 （ T1） ，8：2（ T2） ，5：5（ T3） ，2：8（ T4） ，and ，supplemented with distilled water（CK）， molasses（TM），Lactobacilus plantarum（LP），or Lactobacillus buchneri （LB）.After 40 days of fermentationat room temperature，nutritional and fermentation qualities were analyzed.Results showed that mixed silage significantly improved quality compared to single-crop silage （ .P<0.05⟩ .Crude protein，neutral detergent fiber（NDF），and acid detergent fiber（ADF） increased significantly with higher triticale proportions （ P< O.05）.The TM group exhibited higher water-soluble carbohydrates and lower ADF than CK （ 0 Acetic acid，propionic acid，and pH increased with increasing triticale ratios （P<0.05） .Compared to CK，LB increased acetic acid but reduced propionic acid（ P<0.05 ，whileTMlowered pHand elevatedlacticacid（ P< 0.05）.In conclusion，the 8： 2 ratio combined with molasses significantly enhanced silage quality.

饲用小黑麦（TriticosecaleWittmack）是由小麦属和黑麦属经人工杂交、染色体加倍而培育出的优良的粮饲兼用型禾本科作物，其鲜嫩植株可作为青贮饲料和鲜饲料加以利用[1]。（剩余13966字）
