摘要
通过正交设计,对大麦新品种"蒙啤麦3号"设置肥料与密度效应梯度,探索肥料与密度效应对"蒙啤麦3号"产量与蛋白质含量的影响,明确"蒙啤麦3号"在内蒙古中部旱作区适宜的肥料施用量及播种密度。结果表明:啤酒大麦"蒙啤麦3号"在内蒙古中部旱作区的生产潜力为2 241.0 kg/hm2,与之匹配的肥料与密度为,纯氮135.0 kg/hm2,纯磷55.5 kg/hm2,纯钾22.5 kg/hm2,密度600.0万株/hm2,此条件下,籽粒蛋白含量及千粒重符合GB/T7416-2008之要求。
Through orthogonal experiment designs, effects of fertilizer and density were studied on new barley variety Mengpimai 3＇ in middle dry region of Inner Mongolia. The results showed that the best scheme of fertilizer and planting density was that the application of N was 135 kg/hm^2 , P 55.5 kg/hm^2 , K 22.5 kg/hm^2 , the amounts of basic seedling was 6 million per hm^2 , the yield was 2 241 kg/hm^2 under the condition. Furthermore, the protein content and 1 000 grains weight were accord with National Standard GB/T 7416 - 2008.
