适宜内蒙古典型河套灌区种植的玉米青贮品种筛选试验研究

摘要

To accelerate the extension of feed production techniques and improve the nutritional level of livestock fed on grass,7 strains of corn,including Silage 67,Jingang 50,Silage 2,Xingzhu 1,Jinling 7,Jinling 10 and Jinling 14,were introduced by Grassland Working Station of Hangjinhou County of Inner Mongolia in 2009,and the comparative trial was carried out.The result indicated that the fresh yield of Xingzhu 1 was the highest,but it was the lowest in GI;the series of Jinling strains were better both in yield and GI compared with other strains,which should be generated at river irrigation district.%为了加快饲料生产技术推广和提高食草家畜的营养水平,内蒙古杭锦后旗草原站于2009年引进7个品种的玉米进行品种对比试验,分别为青贮67、金刚50、青贮2号、兴贮1号、金岭7号、金岭10号、金岭14号。结果表明,兴贮1号每667m2鲜草产量最高,但GI值较低。金岭系列产量和GI值都表现较好,适合在典型河套灌区推广种植。
