不同施肥处理对高油玉米产量性状影响的灰色关联度分析
Grey Correlation Analysis of Different Fertilizer Treatments on Yield Traits of High Oil Corn
【摘要】 文章以高油玉米珍油玉3号为试验材料,研究不同施肥水平对该品种产量与穗部性状的影响。通过2年的施肥试验,结果表明,出籽率、行粒数和穗行数是影响珍油玉3号籽粒产量构成的关键因子。考虑投入产出比,氮磷钾水平Ⅳ(复合肥562.5kg/hm2,尿素750 kg/hm2)是最佳穗部性状与籽粒产量的施肥水平。
【Abstract】 The effects of fertilizer application on panicle traits and yield were studied through field experiment of Zhenyouyu No. 3. The results for two years running,seed rate,kernels per row and row number were main associated factors on yield and quality of Zhenyouyu No. 3. Considering the input-output ratio,and the treatment Ⅳ( compound fertilizer 562. 5 kg / hm2,urea 750 kg/hm2) could get the best panicle traits and grain yield.
