摘　　要：为探讨稻秸、玉米粉与紫花苜蓿混合青贮的效果及有氧稳定性,将5个不同比例(0、5%、10%、15%和20%)的稻秸分别与紫花苜蓿、玉米粉进行混合青贮,30d后测定青贮饲料的各项指标。结果表明:保证适宜含水量的前提下,各处理组青贮饲料的V-score评分均较高,属于良好青贮饲料,而且可在开包后36h内保持较好的有氧稳定性。随着稻秸添加量增加,青贮料pH值、NDF含量显著升高(P<0.05),ADF、WSC含量呈增加趋势,RFV大幅降低。In order to investigate the effect of mixed silage containing different proportions of rice straw, corn meal and alfalfa on the quality and aerobic stability of mixed silage, rice straw at five different proportions(0, 5%, 10%, 15% and 20%) of rice straw were mixed with alfalfa and corn meal, respectively, and the indicators of silage were measured after 30 days of ensiling. The results showed that under the premise of ensuring the appropriate water content, the V-score of silage in each treatment group was higher than that in the control group, which were good quality silage, and could maintain good aerobic stability with 36 h after opening the package. With the increase of rice straw addition, pH value and NDF content increased significantly(P<0.05), ADF, WSC content increased, and RFV decreased significantly.
