| 摘要: |
| 采用野外调查采样结合室内分析的方法，研究了豫西地区农田土壤有效铜含量的分布特征及其影响因素。结果表明，豫西地区全铜含量介于23.60～52.70 mg·kg-1，平均30.17 mg·kg-1，有效铜含量介于0.28～4.13 mg·kg-1，平均0.89 mg·kg-1，表现为山地<丘陵<平原。本区域有15.
93%的样点有效铜含量低于缺铜临界值，有60.44%的样点濒临缺铜。土壤有效铜含量与有机质、全氮含量呈显著线性正相关关系，与pH值呈显著负相关关系。前茬玉米土壤有效铜含量最高，平均1.18 mg·kg-1，前茬红薯土壤有效铜含量最低，平均0.63 mg·kg-1。 |

| Abstract: |
| Distributing characteristics of and factors contributing to soil available Cu in the farmland in the West Henan were studied. Results showed that total soil Cu was mostly within the range of 23.60～52.70 mg·kg-1, with an average of 30.17 mg·kg-1, and available Cu was mostly within the range of 0.24～4.13 mg·kg-1, with an average of 0.89 mg·kg-1
. Available Cu in soil increased with the order of mountain area＜hilly area＜plain area. In this area, content of soil available Cu among 15.93% of total samples was below the minimum threshold, accounting for 60.44%. parameters including content of organic matter, total nitrogen, pH was related with soil available Cu, with a positive relationship between soil available Cu and organic matter, and a negative relationship between soil pH and available Cu. The soil available Cu content was 1.18 mg·kg-1, with corn being the preceding crop. By contrast, it reduced to 0.63 mg·kg-1, with sweet potato as the preceding crop. |
