种植密度对‘浚单29’产量和品质的影响
Effects of Planting Density on Yield and Quality of‘Xundan 29’
摘要
Abstract
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.关键词
