为了研究玉米产量与子粒品质的关系,采用最新通过国家审定的玉米新品种‘浚单29’,通过设置5.25～9.00万株/hm2共6个种植密度,研究了玉米子粒产量和品质随种植密度的变化规律。结果表明,‘浚单29’的产量潜力大,适宜种植密度范围宽,在5.52～8.70万株/hm2密度范围内,均有11155.4 kg/hm2以上的产量潜力。随着种植密度的增加,‘浚单29’籽粒的蛋白质、粗脂肪含量呈下降趋势,淀粉含量呈上升趋势,赖氨酸含量则呈波动变化。综合考虑‘,浚单29’的种植密度以5.52～6.75万株/hm2为宜。

A field trial with a maize variety‘Xundan 29’was conducted in Hebi,Henan,China in 2009 to investigate the effects of six different planting densities（ranging from 52.5 to 90.0 thousand plants/hm2） on its yield and quality.It is found that‘Xundan 29’had a higher yield potential and a wider suitable density scope.It could obtain a higher yield of more than 11155.4 kg/hm2 at 5.52 × 104-8.70 × 104 plants/hm2.With the increasing of planting density,the protein and crude fat contents in‘Xundan 29’was decreased and starch content was increased,while the lysine content fluctuated.Based on the above comprehensive analyses,it is inferred that the optimal planting density should be varied from 5.52×104to 6.75×104plant/hm2.
