摘　　要：本文通过对3个不同类型的高产小麦品种的植株定期取样分析测定,讨论了高产小麦全生育期中植株茎秆和叶片氮素含量、积累强度及积累进程的差异及变化,进而探讨了超高产小麦的合理施氮对策。This paper discussed the difference and change of nitrogen content, accumula tion intensity and accumulate of culm and leaf in all the growth periods. In The experiment sam ples were taken at different time to analyze 3 different type high-yielding winter wheat varieties. The nitrogen application in super-high-yielding winter wheat was further discussed.
