摘要
研究表明,皖单4号、掖单2号在皖南广德红黄壤地区具有较好的适应性,经济产量较高。在玉米生育后期雨水较少情况下,氮素水平可减少60kg/hm 2,皖单4号、掖单2号产量达6 700kg/hm 2。
The result showed that maize variety Wandan No.4 and Yedan No.2 had a good adaptability in Red yellow soil in south Anhui and high yield. When the precipitation was smaller in the late period of maize growth,the amount of N fertilizer application might be cut down by 60kg/hm 2 and the yield of Wandan No.4 and Yedan No.2 amounted to 6 700kg/hm 2.
