用火焰原子吸收法测定两个地区土壤及其生长作物中的K、Na、Ca、Mg、Zn、Cu、Fe、Mn 8种元素的含量,比较了K与Na、Ca与Mg、Zn与Cu、Fe与Mn的含量比例关系。结果表明,河北土壤、山西土壤、河北玉米和山西玉米中各自比例为:1.70、0.37、61.50、8.06;1.05、0.85、23.99、1.93;29.54、0.02、35.08、6.13;15.02、0.02、39.27、2.00。两种土壤和玉米的一些元素比例存在显著性差异。
The contents of K, Na, Ca, Mg, Zn, Cu, Fe and Mn in two soils and their growing crops were determined by flame atomic absorption spectrometry. The contents of K, Na, Ca, Mg, Zn and Cu , Fe and Mn content ratio relationship. The results showed that the proportions of Hebei soil, Shanxi soil, Hebei corn and Shanxi corn were respectively 1.70,0.37,61.50,8.06; 1.05,0.85,23.99,1.93; 29.54,0.02,35.08,6.13; 15.02,0.02,39.27,2.00 . There was a significant difference in the proportions of some elements between the two soils and maize.
