从安徽各地13个土类、15种母质上采集耕层土样1006个,剖面土样394个,分析了有效性B、Mn、Cu、Zn、Fe、Mo6种元素的含量,结果表明:1、安徽省土壤微量元素缺乏频率约为B75%、Mo85%、Zn35%、Cu25%、Mn20%、Fe10%(仅占碱性土壤10%)。2、土壤pH与B呈极显著正相关;与Fe和交换Mn呈极显著负相关;与缓效Mn呈似抛物线相关;与Mo、Zn则无明显相关。3、各元素之间分布上也有一定相关性,其中Cu相关面最广,它除了与缓效Mn以外,与其他元素都有极显著正相关。4、聚类分析显示,在土壤形成和熟化过程中,Cu、Fe的有效化和移动性经常有相似的行为。
Mn, Cu, Zn, Fe and Mo were collected from 13 soil types and 15 kinds of parent materials in Anhui Province. The results showed that 1 The trace elements in soil in Anhui province lacked the frequency of B75%, Mo85%, Zn35%, Cu25%, Mn20%, Fe10% (only 10% of alkaline soil). Soil pH had a significant positive correlation with B, negative correlation with Fe and exchangeable Mn, parabola with slow Mn, and no significant correlation with Mo and Zn. There is also a certain correlation between the distribution of the various elements, of which the most relevant aspects of Cu, which except with slow Mn, with other elements have a very significant positive correlation. Cluster analysis showed that the activity and mobility of Cu and Fe often have similar behavior in soil formation and maturation.
