高纬寒地青贮玉米引种筛选试验

Introduction Screening Test of Silage Maize in High Latitude Cold Region

为研究高纬度寒地青贮玉米的高产栽培技术,使农民增产、增收,以5个青贮玉米品种(系)为试验材料,进行了高纬寒地青贮玉米引种筛选试验。结果表明:不同品种间生物产量存在一定差异,中单5384产量最高。通过对生育期、株高、穗位、茎粗、单株鲜重、单株穗鲜重及生物产量综合分析,最适于黑河地区种植的青贮玉米品种应为中单5384。

In order to study the high yield cultivation of silage maize in hight latitude cold region, and increase the production and income of farmers,taking 5 silage maize varieties（lines） as the test materials, screening introduction experiment of silage maize in high latitude cold region was conducted. The results showed that there existed significant differences of inbiomass among different varieties（lines）, the yield of Zhongdan 5384 was the highest. Through the investigation of growth period, plant height, ear, stem diameter, fresh weight of single plant,ear fresh weight and biomass yield,the most suitable for planting was Zhongdan 5384 in Heihe area.
