对剑河县12乡镇102个土样本的有效态微量元素进行了测定,研究了土壤中有效锌、有效铜、有效锰、有效铁、有效硼元素在剑河每个乡镇中的分布及含量,研究结果表明,有效硼的含量平均为0.50 mg/kg,有效锌平均为2.24 mg/kg,有效铜平均为2.23 mg/kg,有效铁平均为142.06 mg/kg,有效锰平均为73.84 mg/kg。有效铁、有效锰含量属于高等级。有效铜含量与有效锌、有效铁、有效锰含量间均达到显著的相关关系,有效锌含量与有效铁、有效锰含量间均达到极显著相关关系,有效锰含量与有效铁间达到极显著相关关系,有效硼与其他元素间均不相关。在农业生产过程中,针对不同乡镇的土壤微量元素状况,应在长期施用氮磷钾肥料的基础上,因地制宜地增施相应硼肥,减少铁肥、锰肥的施用。
The effective trace elements in 102 soil samples of 12 townships in Jianhe County were determined. The distribution and content of available zinc, available copper, available manganese, available iron and available boron in each soil of Jianhe were studied. The results showed that the effective boron content averaged 0.50 mg / kg, the available zinc average was 2.24 mg / kg, the available copper average was 2.23 mg / kg, the available iron average was 142.06 mg / kg and the available manganese was 73.84 mg / kg . Available iron, effective manganese content belongs to a high level. Available copper content and effective zinc, available iron, available manganese content were significantly related to each other between the effective zinc content and available iron, available manganese content were extremely significant correlation between the effective manganese content and the effective iron reached a significant correlation Relationship, effective boron and other elements are not related. In the process of agricultural production, according to the situation of soil trace elements in different towns and townships, the application of NPK fertilizers should be based on the long-term application of appropriate boron fertilizers to reduce the application of iron and manganese fertilizers.
