河南省主要土类耕层中几种微量元素全量分析

Investigation of Several Microelements in Plough Layer in the Major Soils in Henan Province

对河南省潮土、褐土、黄褐土、砂姜黑土、黄棕壤、红粘土6种土类耕层的100个土壤样品进行了Fe、Mn、Cu、Zn全量分析,结果表明:在所测的各类土壤中,全Fe含量最高,其次是全Mn含量。进一步研究发现:所测土壤中,Cu和Zn含量与土壤pH值之间存在一定的关系,pH值高的土壤中全Cu含量高于全Zn;pH值低的土壤则相反。

The contents of four microelements of 100 plough layer samples of fluvo-aquic soil, cinnan：on soil, yellow cinnamon soil, lime concretion black soil, yellow brown soil and red clay soil were analyzed in Henan province. The result showed that the amount of Fe in detected soil samples was highest, and Zn was next to its. The content of Cu in fluvo-aquic, cinnamon soil and red clay soil was higher than that of Zn. On the contrast, the content of Zn was more than that of Cu in yellow cinnamon soil, yellow brown soil and lime concretion black soil. Further research indicated that certain relations were existed between the contents of Zn and Cu and the soil pH in 100 soil samples. In the high pH soil, the content of Cu was higher than that of Zn. However, the result is opposite in the low pH soil.
