[目的]探讨灵宝某化工厂周边土壤有效养分含量,为利用重金属超富集植物修复污染土壤提供参考。[方法]对灵宝某化工厂周边土壤有效养分含量进行了测定。[结果]土壤中有效氮含量极缺乏或很缺乏,土壤有效磷含量极缺乏,土壤有机质含量缺乏。[结论]如要对该重金属污染地区通过超富集植物进行修复,则应根据植物的需肥规律进行合理施肥。
[Objective] The research aimed to discuss the effective soil nutrient content around a chemical plant in Lingbao, and provide a reference for remediation of contaminated soil with heavy metal hyperaccumulator. [Method] The effective soil nutrient contents around Lingbao Chemical Plant were determined. [Result] The content of available nitrogen in soil was extremely scarce or lacking, the content of available phosphorus in soil was very scarce, and the content of organic matter in soil was scarce. [Conclusion] If the heavy metal contaminated area should be rehabilitated by hyperaccumulators, fertilization should be carried out according to the rule of plant fertilization.
