| 摘 要： | 研究了山东省3大土类2个产量水平土壤表层的5种主要微量元素(Zn、Fe、Mn、Cu、B)含量及其与土壤主要理化指标的相关性.结果表明:不同土类的微量元素含量有明显差异,其特征是棕壤严重缺B,富含Fe和Mn.高产农田的有效Fe含量为13.10mg/kg,显著高于中低产田:有效Mn、有效Zn、有效Cu和有效B的含量分别为16.5、1.63、1.40、0.92mg/kg,也高于中低产田,但差异不显著.高产农田缺Mn、轻缺Zn比例分别为9%和33%,略大于中低产田,而缺B比例为28%,则略低于中低产田,其他微量元素不缺.

| Abstract: | In this paper the contents of five microelements (Zn, Fe, Mn, Cu, B) and their relationship with other physico-chemical indices of three type soils at two yield-levels in Shandong Province were studied. Results showed that concentrations of five microelements were significantly different among different types of soils. In brown soil, B was deficient but Fe and Mn were sufficient. In soils studied available Fe content of high-yield fields was significantly higher than low-yield fields. The insufficient percentages of available Mn, Zn and B were 9%, 33% and 28% in high-yield fields, respectively. |
