“一深两增”玉米高产模式下新品种产量潜力研究
Study on the Yield Potential of New Maize Varieties in one deep and double increase Productive Mode
摘要
Abstract
In order to offer suitable varieties to 'one deep and double increase' high yield mode in spring corn area of Shanxi Province,ten maize cultivars,including Dafeng30,Dafeng26,Qiangsheng51,Qiangsheng101,Fushengyuan52,Bingdan390,Luyu36,Xianyu335,Zhengdan958 and Beinong110,were used as the experimental materials to study the potential yield and yield components.The results showed that the yield of Qiangsheng101 and Dafeng26 were significantly higher than those of other varieties,and their yields were both above 16 500 kg · hm 2.Yield potentials of Qiangsheng101 and Dafeng26 in 'one deep and double increase' high yield mode were 19 148 kg · hm-2 and 17 691 kg · hm-2,respectively.Qiangsheng51,Dafeng30,Fushengyuan52,Xianyu335 showed general yield performance.Bingdan390 and Luyu36 had excellent seedling maintained rates which were higher than 90％.In general,all varieties except Beinong110 could be used as suitable cultivars for the high water and fertilizer corn-belt in Shanxi in 'one deep and double increase' high yield mode.关键词
