Abstract为了探讨玉米(Zea mays)作为青贮饲料在高寒牧区的品质及丰产栽培技术,开展了玉米品质分析及密度、追肥、玉米与箭筈豌豆混播试验研究.结果表明:4个玉米品种的粗蛋白质2.48%~4.49%,粗脂肪0.40%~0.72%,中性洗涤纤维(NDF)67.86%~73.45%,酸性洗涤纤维(ADF)37.30%~46.39%.玉米在高寒牧区可以高密度种植,‘金穗3号’每公顷种植21万株时的鲜草和干草产量比种植15.57万株时增产22.82%和16.55%,‘中玉9号’增产14.33%和9.79%.拔节期每公顷追施尿素150kg时比不追肥时鲜草和干草的产量,‘金穗3号’增产22.92%和27.32%,...
