[目的]对豫北平原潮土不同质地的主要养分现状及消长原因进行分析。[方法]抽取豫北平原国家测土配方施肥补贴项目2005～2012年部分潮土取土化验数据,共计5 256个,与1986年第二次土壤普查土样化验结果进行对比。[结果]潮土有机质平均含量为12.20～15.00 g/kg,全氮平均含量为0.70～1.00 g/kg,有效磷平均含量为13.77～14.17 mg/kg,速效钾平均含量为96～146 mg/kg。[结论]与第二次土壤普查相比,豫北平原潮土有机质、全氮、有效磷、微量元素均呈上升趋势,氮磷钾处于中等水平,铜铁锌锰处于盈余水平。
[Objective] The research aimed to analyze the main nutrient status and the causes of the growth and decline of different texture of the tideland soil in the Yubei Plain. [Method] A total of 5 256 soil samples were collected from 2005 to 2012 in the national soil testing and fertilization subsidy project of Yubei Plain. The results were compared with those of the second soil census in 1986. [Result] The average content of organic matter in the alluvial soil was 12.20 ~ 15.00 g / kg, the average content of total nitrogen was 0.70 ~ 1.00 g / kg, the average content of available phosphorus was 13.77 ~ 14.17 mg / kg and the average content of available potassium was 96 ~ 146 mg / kg. [Conclusion] Compared with the second soil survey, the organic matter, total nitrogen, available phosphorus and trace elements in the intertidal soil in the Yubei Plain all showed an upward trend, while the N, P and K levels were moderate and the Cu, Fe, Zn and Mn levels were in surplus.
