摘要
通过吉林省2994个土壤样本的测定,查明了吉林省土壤微量元素铜和锌的含量与分布。土壤全量微量元素铜和锌低于我国土壤的平均含量。由于成土母质和土壤类型的不同,使土壤微量元素的含量变化较大。土壤有效锌普遍缺乏,少数土壤缺铜。并论述了土壤有效微量元素的含量与土壤性质的关系。
Making an analysis of 2994 soil samples of Jilin Province, present paper gives the content and distribution of trace elements Cu and Zn in the Soils of Jilin Province. The totel contens of Cu and Zn in soils of Jilin Province are lower than the average contents of Cu and Zn in the soils of China. Owing to the diverse parent materials and soil types, the contents of trace elements in the soils fluctuate greatly. The available Zn is deficient in the soil commonly and the Cu is deficient only in several soils. The relationship between available trace elements in soils and the properties of the soils are described.
