内蒙古河套灌区大麦新品系“08PJ-36”肥料与密度效应研究

Effect of Fertilizer and Density on New Barley Variety “08PJ-36” in Hetao Irrigation District in Inner Mongolia

通过正交设计,对大麦新品系"08PJ-36"设置肥料与密度效应梯度,探索肥料与密度效应对"08PJ-36"产量与品质的影响,确定"08PJ-36"在黄灌区适宜的肥料施用量及播种密度。结果表明:啤酒大麦"08PJ-36"在内蒙古河套灌区生产潜力可达586.15 kg/667 m2,与此适应的肥料与密度为,纯氮9.0 kg/667 m2,纯磷8.1 kg/667 m2,纯钾1.5 kg/667 m2,密度31万株/667 m2,此条件下,籽粒蛋白质含量及千粒重能够符合GB/T 7416—2008之要求。

To set up fertilizer and density gradient effect for the new barley variety ＂08PJ -36＂ through orthogonal experimental design, study the effects of fertilizer and density on the yield and quality of ＂08PJ -36＂ and confiim the appropriate fertilizer rate and density for ＂08PJ - 36＂ in Irrigation Area The result shows that the potential yield of malting barley ＂08PJ - 36＂ in Hetao Irrigation District in Inner Mongolia can reach 8 792. 25 kg/hm2 while the fertilizer rate should be N of 135.0 kg/hm2, P of 121.5 kg/hm~, K of 22. 5 kg/hm2 and planting density should be 4. 65 × 106 strains/hm2. Under the conditions mentioned above, the protein content and 1 000 grain weight can meet with the requirements of GB/T 7416 -2008.
