摘要
对临汾市39个农业土壤样品有效态微量元素铜、锌、铁、锰的含量进行了测定,并对其分布特点,测定结果进行了分析与评价,旨在为该地区合理施用微肥,提高农作物产量和质量提供科学依据。结果表明:临汾市农业土壤中除有效铁分布差异较大外,其它微量元素分布较均匀。微量元素中有效铜平均含量为1.775 mg.kg-1,属2级水平;有效锌平均含量为1.992 mg.kg-1,属2级水平;有效铁平均含量为8.613 mg.kg-1,属3级水平;有效锰平均含量为9.110 mg.kg-1,属3级水平。
After determining the content of available trace elements of copper,zinc,iron,manganese of the 39 agricultural soil samples of Linfen,we analyse the distribution and the determination.The main purpose is to provide a scientific basis to fertilize the micro-fertilizer in the region rationally and improve the yield and quality of the crop.The result shows that,in addition to the obviously different distribution of available iron,other trace elements are in a more even distribution in Linfen.In the trace elements,the average content of available copper is 1.775 mg·kg-1,it is at the second level;the average content of available zinc is 1.992 mg·kg-1,it is also at the second level;the contents of available iron and manganese are 8.613 mg·kg-1and 9.110 mg·kg-1,respectively,all are at the third level.
