济阳县土壤元素有效量及其影响因素研究

Study on Available Contents and Influencing Factors of Soil Elements In Jiyang County

摘要:

通过对济阳县生态地球化学调查研究，该区受成土母质来源、土壤类型、地形地貌及其理化性质等因素影响，土壤元素全量、有效量及有效度表现为：低平洼地土壤中K，P，N，Se，Mn，Fe，Zn，Cu和Mo全量较高，P，N，Se和Cu有效量较高，显示为低平洼地为黏质成分的沉积成因特点；而决口扇形地区土壤Cu，Mo，N，Zn，B有效量和全量均偏低。富含有机质，且pH相对较低的潮土中Se，Cu，Mo和B等元素有效度较高，贫有机质、pH相对较高的草甸风沙土中N，Fe，Cu，Mo，B和S等元素有效量较低，但K有效量和有效度均较
