黑龙江省主要类型土壤中微量元素含量的垂向分异研究

Vertical Variation of Element Contents in the Main Soil Types of Heilongjiang Province

黑龙江省主要类型土壤中微量元素在剖面中的变化趋势是不同的 ,这与不同类型土壤的成土母质、成土条件、土壤有机质和土壤中粘粒含量等有关。各种类型土壤表层中微量元素Fe、Mn、Zn、Cu、Co的有效量均大于其有效态临界值 ,并且Cu、Zn、Mn全量与有效量之间呈明显的相关关系。

Vertical variation of trace elements in the profiles of main soils of Heilongjiang province is different, which is relative to the parent material of the soil, conditions of the soil formation, contents of organic matter and clay particle. Availability contents of Cu, Zn, Mn, Fe and Co in surface soil horizon exceeded the critical value of availability, and the relationship between total contents and available contents of five elements has been established.
