摘　　要：本试验对青贮专用玉米品种雅玉8号和生产上常用的籽粒玉米郑单958、浚单20不同收获时间的生物产量及青贮后主要营养成分进行了测定,结果表明:这三个品种在青贮后主要营养指标差异不明显,基本符合国家青贮玉米标准,雅玉8号生物产量高于其他两个普通玉米品种,但酸性洗涤纤维含量略超国家标准。The main nutritional harvested at different time after components of biological yield and silage in the test of three maize varieties were determined, the results showed that： Yayu 8, Zheng Dan 958, and Xundan 20 the three varieties in the main nutrient indexes of silage were not significant difference, which accords with the national standard, the biological yield of Yayu 8 was higher than the other two maize varieties, and acid detergent fiber content was slightly higher than the national standard.
