摘要: 在长江中下游黄棕壤上采集129个土样,测定了其中14种元素(13种微量元素和Fe)的全量含量,比较了不同岩石上发育的黄棕壤元素含量的差异,分析了其剖面分布特征。讨论了目前农业生产中广泛关注的5种微量元素和Fe的有效态含量在黄棕壤剖面中的迁移分布及其影响因素。

Abstract: A total of 129 samples were collected and the environmental geochemical characteristics of 13 kinds of trace elements and Fe in the yellow brown soil were studied, which has the largest distribution area in zonal soils of middle and lower reaches of the Yangtze River.The main results are as follows:(1) Pb、Ni、Cr、Hg、Co、V、Mn、F and Fe are relatively high in total contents, As 、Se 、Cu、 Zn and Cd are moderate or little lower.The available B、Cu、Zn and Mo are all insufficient.(2) Most of trace elements have their highest total contents in the subsoil and their highest available contents in the epipedon.(3) The sequences of total contents of trace elements in the yellow brown soil are basalt soil > limestone soil > granite soil.(4) The positive correlation between the contents of total and available Zn & Mo arrives to significance or extreme significance level in the yellow brown soil of Hubei province.The positive correlation between available contents of B & Mo and pH of the yellow brown soil is proved to be extreme significance.But for Fe & Zn, the negative correlation is also the same level.The contents of available B、Mn、Cu、Zn and Mo have significant or extreme significant positive correlation with the organic matter content in the soil.The authors think it necessary to plough deeply and apply organic fertilizer to improve the contents of available trace elements in the yellow brown soil.
