摘要
为摸清山东典型植烟区土壤微量元素有效态含量分布情况,采集和分析了临朐、蒙阴、诸城、费县、五莲、莒县6个主要植烟县的烟田耕层和剖面土样。结果表明:①耕层土壤有效Fe和Mn含量丰富,有效Cu含量适中,有效Zn含量较低。②石灰性砂页岩发育的土壤中微量元素有效态含量相对较低。③有效态Fe、Mn和Zn主要为表层富集型,有效Cu垂直分布相对均匀。④土壤有效态Fe、Mn、Cu和Zn含量随pH升高而降低,随有机质增加而增加;pH是影响有效态Fe和Mn的重要因素,而有机质是影响有效态Cu和Zn的重要因素。
In order to study the content characteristics of available microelements in typical tobacco-planting soils of Shandong Province, soil samples were collected from 6 main tobacco-planting regions, i.e., Linqu, Mengyin, Zhucheng, Feixian, Wulian and Juxian and the available contents ofFe, Mn, Cu and Zn in the samples were analyzed. The results showed that： 1） the contents of available Fe and Mn in the plough horizon were plentiful, while those of Cu and Zn were moderate and insufficient respectively; 2） available Fe, Mn and Zn were obviously accumulated in plough horizon while available Cu distributed homogeneously in the profile; 3） available Fe, Mn, Cu and Zn in soils derived from calcareous purple sandstone were significantly lower than from other parent materials; 4） significantly negative correlations were observed between the contents of available Fe and Mn and soil pH while a significantly positive correlation found between soil available Cu, Zn and soil organic matter.
