摘要
[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 aim was to make comprehend of soil effective nutri- ent content of chemical plant periphery in Lingbao, and provide some fi＇uitful reference for remedying the heavy metal contaminated soils by hyper accumula- tors. [Method]This paper analyzed soil effective nutrient content near a chemical plant. [Result]The soil available nitrogen content was lack or insufficient, the con- tent of available phosphorus in soil was very lack, and the organic matter content was lack. [Conclusion] If we will remedy the heavy metal contaminated soils by hyper accumulators, it should be rational fertilization according to the rule of the fertilizer plants need.
