摘要： 重庆山区玉米秸秆丰富，但多被焚烧，造成资源浪费。青贮发酵能够利用现有的秸秆发酵成富含蛋白质、多种维生素和无机盐的青贮饲料，目前青贮添加剂已被广泛应用到秸秆青贮中，本试验为探讨不同化学、生物添加剂对重庆山地玉米秸秆青贮料品质的影响，找出最佳青贮添加剂种类及剂量。本试验以重庆高山地区的不带玉米果穗的玉米秸秆为原料，进行甲酸、EM菌和纤维素酶不同添加剂量的青贮饲料发酵试验。结果表明：玉米秸秆青贮过程中添加甲酸、EM菌、纤维素酶可有效改善青贮饲料品质和营养价值，其中以混合添加EM菌和纤维素酶、添加3 mL/kg甲酸效果最佳，pH分别为4.33、4.28，乳酸含量分别为3.27%、4.06%，粗蛋白含量分别为2.99%、2.34%，其青贮饲料感官评定都为优。这两种处理方法可获得较理想的玉米秸秆青贮饲料，可改善玉米秸秆青贮饲料的发酵品质，可作为重庆山区玉米秸秆青贮的依据。

Abstract: The resources of corn straw were rich in Chongqing Alpine Regions, but many were burned, resulting in a waste of resources. Fermentation could take advantage of existing straw fermented into rich in protein, vitamins and inorganic salts silage. Silage additive had now been widely applied in straw silage. In order to study the effects of different microbial preparations on the quality of corn straw silage, corn straw of Chongqing Alpine Regions carried out fermentation of silage by adding different percentages of formic acid, EM fungi and cellulase. The results showed that during the fermentation process of corn silage, adding formic acid, EM fungi and cellulase could improve and increase the quality and nutrient value of silage. The effects of 3 mL/kg formic acid and EM fungi+cellulase were the best, obtaining good silage corn stalks, improving the quality of silage fermentation. pH values were 4.33, 4.28, lactic acid contents were 3.27% , 4.06% , crude protein contents were 2.99% , 2.34% , and the sensory evaluation of silage were excellent. Both treatment methods could available to the ideal corn stalk silage, improving the fermentation of corn stalk silage quality, being used as a basis for silage corn stalks in Chongqing Alpine Regions.
