摘　　要：为了丰富黑龙江地区的饲草资源,缓解高蛋白青饲料短缺问题,本研究将经品种品质比较试验筛选出的青贮玉米(Zea mays)‘金岭青贮10号’(乳熟末期)分别与不同生育期相遇的‘黔豆7号’(盛花期)、‘中黄16’(结荚末期)和‘HZ8009’(鼓粒末期)3个饲用大豆(Glycine max)品种(系)以质量比为0:4、1:3、 2:2、 3:1和4:0混合后,研究青贮玉米和饲用大豆混配后的饲用价值和潜力,分别测定粗蛋白(CP)、中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)含量3个主要饲用品质指标,并利用熵权法的综合多指标决策分析方法 (TOPSIS)进一步对饲用品质和饲用价值进行综合分析和评价。结果表明,青贮玉米与不同时期饲用大豆品种(系)在不同混配比例下对饲用品质和饲用价值有不同程度的影响,且乳熟末期的金岭青贮10号与鼓粒末期的‘HZ8009’的质量混配比为3:1时,饲用价值较高。To enrich forage resources in Heilongjiang Province and alleviate the shortage of high protein green fodder, in this study, the forage value and potential of mixed silage corn with forage soybean was evaluated by mixing ’Jinling Silage 10corn’ at the milk stage with three forage soybean varieties(strains) harvested at different stages. The three forage soybean varieties used were: ’Qiandou 7’(late flowering stage), ’Zhonghuang 16’(late pod-setting stage), and ’HZ8009’(late podfilling stage). Silage corn was mixed with forage soybean at five different mass ratios(0 : 4, 1 : 3, 2 : 2, 3 : 1, and 4 : 0).Crude protein(CP), neutral detergent fiber(NDF), and acid detergent fiber(ADF) contents were measured. Forage nutritive quality and value were analyzed and evaluated using technology for order preference by similarity to ideal solution(TOPSIS). The results showed that the mixing ratio of the silage corn and forage soybean varieties affected the feed quality and value to different extents, and the feeding value was higher when ’Jinling Silage 10’ at milk stage and ’HZ8009’ at late pod-filling stage were mixed at 3 : 1.
