| 摘 要： | 土壤中的微量元素在动植物生活中所起的重要作用日益被人们所重视.了解土壤中的这一部分资源对指导微量元素肥料的施用,从而达到农业增产以及对消除由土壤微量元素缺乏或过剩引起的某些动植物病害均具有重要的意义.探讨土壤微量元素在土壤剖面中的累积和迁移及其地理分布规律,则可进一步阐明土壤发生过程与生物地球化学特性的关系.

| Abstract: | Present paper gives the content and distribution of trace elements,including Mn,Ti,Cu,B,Cr,Zn,Mo,Co,Ni,V,Sr,Ba,Pb and Sn,in soil profiles and parent materials of north-eastern China and eastern Inner Mongolia.Geographical distribution of Cu,Mn, Mo,Zn,B and Co in this region has also been studied.111 soil profiles (360 soil samplcs) were examined for the above purposes.The average content of total trace elements in various soil types are given below:Mn 840 ppm,Ti 6,500 ppm,Cu 22 ppm,B 46 ppm,Cr 103 ppm,Zn 85 ppm,Mo 2.2 ppm,Co 23 ppm,Ni 51 ppm,V 92 ppm,Sr 270 ppm,Ba 570 ppm,Pb 26 ppm,Sn 6 ppm. |
