| 摘 要： | 通过研究在不同含量外源汞土壤中施加不同量的氮肥,分析土壤中不同形态汞的转化状况。结果发现,施尿素0.4 g/kg(T3)能显著提高土壤活性,促进土壤中汞向有效态转化,同时可提高植物对土壤中汞的吸收;其余氮肥水平对土壤不同形态汞的转化活性依次为施尿素0.6 g/kg、施尿素0.2 g/kg、不施肥处理。

| Abstract: | Through application of various levels nitrogen into the soil with various concentrations exogenous mercury,absorption effects of the different mercury forms transferring into the plant were analyzed.The results showed that the urea 0.4 g/kg(T3) level nitrogen fertilizer could significantly improve soil activity and promoted the mercury transference into the plant.At the mean time it improved plants absorption ability of the soil mercury.The other nitrogen levels' transformation activities on different forms... |
