| 摘 要： | 目的]研究污染土壤中重金属Zn的形态与土壤基本理化性质的关系。方法]将污染水稻土中Zn的形态分别与土壤pH、有机质、CEC等土壤基本理化性质的关系进行了系统研究。结果]土壤全Zn与土壤游离氧化铁呈极显著线性正相关(R2=0.516 4**,n=39),与土壤粘粒(<0.002 mm)呈极显著线性正相关(R2=0.435 8**,n=39),与土壤有机质、CEC、pH值等土壤理化性质无显著相关关系。土壤有效Zn量与土壤全Zn量呈显著线性正相关(R2=0.412 5*,n=20),土壤Zn的有效度与土壤全Zn量呈极显著性负相关(R2=0.357 1**,n=39),土壤Zn的有效度与土壤有效Zn量之间呈极显著线性正相关(R2=0.363 6**,n=39)。结论]该研究对降低土壤污染风险,保证食品质量安全具有重要意义。

| Abstract: | Objective]This study aimed to study on the relationship between heavy metal Zinc forms and physical-chemical properties in polluted paddy soil.Method]The relationship between the forms of Zinc and physical-chemical properties(soil pH,organic matter,soil CEC)was systematically studied in polluted paddy soil.Results] The total of Zinc content was most significantly positively correlated with the soil free iron oxide(R2=0.516 4**,n=39),that was most significantly positively correlated with the soil clay granule(<0.002 mm)(R2=0.435 8**,n=39),and that was no significant correlated with soil physical and chemical properties such as soil organic matter,CEC,pH.The effective Zinc amount was significantly positively correlated with the total Zinc amount(R2 =0.412 5*,n=20),the effective degree of Zinc was significantly negatively correlated with the total Zinc amount(R2=0.363 6**,n=39).Conclusion]This study was of great significance to reduce the risk of soil contamination and ensure food quality and safety. |
