| 摘 要： | 试验分析研究了山西省小麦主产区之一——运城市土壤中钴的含量状况及其影响因素。研究结果表明。运城市4县区土壤全钴含量为1.65～17．85mg／kg，平均6．00mg／kg，略高于缺钴临界值5．0mg／kg，而低于全国平均值11．2mg／kg;土壤有效钴含量为0．060～2．235mg／kg,平均0．694mg／kg。在34个土样中，大约有60％的样品有效钴含量低于均值．而含量高于均值的土样仅占总样品数的40％。试验区主要土类褐土和潮土全钴含量分别为6．17mg／kg和4．73mg／kg，有效钴含量分别为0．708mg／kg和0．589mg／kg。影响土壤中全钴含量的因素主要是成土母质、成土过程和铁锰含量，影响有效钴含量的因素主要是成土母质、成土过程和有机质。 |

| Abstract: | The cobalt contents and its affecting factors in soils of Yuncheng district in Shanxi province were studied.The results were summarized as follows:(1)The contents of total cobalt ranged from 1.65 mg/kg to 17.85 mg/kg,with an average of 6.00 mg/kg,which was little higher than the critical level 5 mg/kg,but lower than the average level of China 11.2 mg/kg.The contents of available cobalt ranged from 0.060 mg/kg to 2.235 mg/kg,with an average of 0.694 mg/kg.The total cobalt contents in the main soil types cinnamon soils and fluvo-aquic soils respectively were 6.17 mg/kg and 4.73 mg/kg,and the available cobalt contents respectively were 0.708 mg/kg and 0.589 mg/kg.(2)The main influence factors to the total cobalt contents in soils were parent material,soil forming process,the contents of iron and manganese.Available cobalt contents were mainly affected by parent material,soil forming process and organic matter contents. |
| Keywords: | total cobalt available cobalt affecting factors |
