大麦新品种蒙啤麦3号肥料与密度效应研究

Effects of fertilizer and density on barley of new variety Mengpimai 3

为明确蒙啤麦3号大麦在内蒙古河套灌区的产量、籽粒蛋白质含量对施肥水平及密度的响应,采用正交试验设计,开展了N、P、K及密度的4因素4水平栽培研究。结果表明:在适期播种的前提下,蒙啤麦3号在内蒙古河套灌区的生产潜力可达626.1 kg/667m^2,与此相适宜的施肥水平和种植密度为纯氮10.24 kg/667m^2、纯磷9.74 kg/667m^2、纯钾8.4 kg/667m^2,密度31.2万株/667m^2;籽粒千粒重及蛋白质含量符合GB/T7416-2008对多棱啤酒大麦品质的要求。

To identify the yield,grain protein content and response on fertilizer and density of Mengpimai 3 in Hetao Irrigation District,Through orthogonal experiment designs, effects of different fertilizer and density were studied on barley. The results showed that Mengpimai 3 fertilizer and planting density was that the application of N was 10.24 kg/667m2,P 9.74 kg/667m2, K 8.4 kg/667m2,the amounts of basic seedling was 3.12×10 5plants/667 m2,and the yield was 626.10 kg/667m2 under this condition.Furthermore,the protein content and 1 000 grain weight were accord with National Standard GB/T7416-2008.
