| 摘 要： | 采用田间试验和化学分析，研究了施氮肥条件下春小麦吸收N、P、K、Ca、Mg、S、Fe、Mn、Cu、Zn十种营养的特点。结果表明，N素营养对春小麦吸收利用各种养分的浓度变化规律无明显的影响，对各个时期的浓度的高低有不同程度的影响；氮肥对各种养分吸收累积量变化规律无显著影响，但对各个时期累积数量有不同程度的影响．N肥的施用对锰的吸收累积无显著影响，对N、P、K、S、Ca、Mg、Fe、Cu、Zn 9种养分的吸收累积量的正面影响达显著、极显著水平。

| Abstract: | The effect of N fertilizer on absorption of N?P?K?Ca?Mg?S?Fe?Mn?Cu?Zn in spring wheat was studied in the field experiment . The results shown that N fertilizer had no dramatic effect on changing the law of nutrient concentration , but changing nutrient content at different stages. Moreover, applicating N fertilizer did not significantly affect the law of various nutrient accumulation , but affected accumulation at different stages. N fertilizer did not significantly affect Mn accumulation , but affected the accumulation of N?P?K?S?Ca?Mg?Fe?Cu?Zn up to sufficient or utmost sufficient. |
