| Abstract: | To explore the effect of different soil configurations on corn production and fertilizer use in alluvial soil area,the experiments of different nitrogen(0,90,180,270,360,450kg/ha)applied in stages on corn were carried out on clip sandy loam and sandy loam with bottom clay in Qingfeng county.The results showed that nitrogen application in stages had a positive effect on growth and development of corn.The number of blades increased by 1-2 leaves compared with CK after tasseling-booting stage,and the height in... |
