| 摘 要： | 采用野外采样结合室内分析的方法,研究了豫西地区有效Zn的分布特征及其影响因素,以期为锌肥的施用提供依据。结果表明,豫西地区土壤全Zn含量介于63.437～164.675mg/kg,平均81.483mg/kg,有效Zn含量介于0.272～7.020mg/kg,平均1.147mg/kg,表现为山地<丘陵<平原。土壤有效Zn与全Zn、海拔高度、全N、速效磷、有机质呈极显著正相关,相关系数依次为0.558、0.201、0.291、0.296、0.222,与pH值呈显著负相关关系,相关系数为0.116;有效Zn与全Zn、pH值的关系用直线方程可以较好拟合,有效Zn与有机质、全N、速效P的关系可用幂函数拟合,有效Zn与海拔高度的关系宜用指数函数拟合;通径分析表明,各因子对有效Zn的影响程度大小顺序为海拔>全N>速效P>pH值>有机质,海拔对Zn有效性的作用最为明显。

| Abstract: | Influencing factors and distributing characteristics of soil available Zn in the western Henan province were studied.Results showed that,total soil Zn was mostly within the range of 63.437-164.675 mg/kg,with an average of 81.483 mg/kg,and available Zn was mostly within the range of 0.272-7.020 mg/kg,with an average of 1.147 mg/kg.Soil available Zn increased in the sequence of mountaintotal nitrogen>available phosphorus>pH>organic.The contents of soil available Zn were mainly affected by altitude. |
