蒙啤麦1号不同播期与施肥处理对产量及蛋白质含量影响

摘要

通过4因素5水平的正交试验,明确了大麦品种蒙啤麦1号在兴安盟井灌区的肥料配比与播期的最佳方案。结果表明：在密度35万株/667 m^2条件下,施纯氮9.0 kg/667 m^2,纯磷9.0 kg/667 m^2,纯钾5.0 kg/667 m^2,播期4月21日时,将获得最高理论产量478.4 kg/667 m^2,籽粒蛋白质含量达11.6%。%Through 4 factor 5 level＇s orthogonal tests,the best scheme of sowing date and fertilizer supplying level was found out on Mengpimai One barley in Xingan League well irrigation district,The experiment result showed that maximum yield is 478.4 kg/667 m^2 and 11.6% of protein content.when fertilizer supplying level was pure nitrogen（N） 9.0 kg/667 m^2,pure phosphorus（P2O5） 9.0 kg/667 m^2,pure potassium（K2O） 5.0 kg/667 m^2,density of 3.5×105/667 m^2,and April 21 of sowing date.
