摘　　要：在不同海拔地区对青贮玉米新品种的生物产量及籽粒产量鲜重、生物产量及籽粒产量干重、农艺性状、穗部性状、生育期和抗逆性等多项指标进行综合分析。结果显示,青贮玉米品种云瑞121和云瑞506可以在保山市的高中低海拔地区及气候类似保山市的其他地区推广种植。该研究为青贮玉米大面积生产应用提供理论依据。We comprehensively analyzed the fresh weight of grain yield and biological yield, the dry weight of grain yield and biological yield, agronomic characters, ear characters, growth period and resistance of silage maize varieties at different altitudes. Yunrui 121 and Yunrui 506 could be widely used in the high, middle and low altitudes areas in Baoshan City of Yunnan Province, as well as other areas having similar climate with Baoshan City. This research provided theoretical basis for the large-scale production of silage maize.
