| 摘 要： | 为黔东南州合理施用微肥提供依据,利用火焰原子吸收光谱法测定采自贵州省黔东南州16个县市稻田土壤有效铁、锰、铜、锌的含量。结果表明:在黔东南州16个县市稻田土壤中有效铁的平均含量为202.88 mg/kg,变异范围为1.38~478.88 mg/kg;有效锰的平均含量为38.97 mg/kg,变异范围为25.60~144.31mg/kg;有效铜的平均含量为6.63mg/kg,变异范围为4.45~8.29mg/kg;有效锌的平均含量值为11.07mg/kg,变异范围为4.57~21.85mg/kg。贵州省黔东南州稻田土壤中有效铁、锰含量处于高等水平,有效铜、锌含量处于中等水平。

| Abstract: | The available Fe,Mn,Cu and Zn content in paddy soil samples collected from 16 counties (cities) of Southeast Guizhou Prefecture was determined by flame atomic absorption spectrophotometer (FAAS) to provide the basis for rational application of trace element fertilizers in Southeast Guizhou.Results:The average available Fe,Mn,Cu and Zn content is 202.88 mg/kg with a variation range of 1.38 ～478.88 mg/kg,38.97 mg/kg with a variation range of 25.60～144.31 mg/kg,6.63 mg/kg with a variation range of 4.45～8.29 mg/kg and 11.07 mg/kg with a variation range of 4.57～21.58 mg/kg in paddy soils of 16 counties (cities) respectively.In conclusion,the available Fe and Mn content is at a high level and available Cu and Zn content is at a moderate level in paddy soils in Southeast Guizhou. |
