| 摘 要： | 通过人工降雨模拟试验研究了稀土元素和磷在土壤中横向流失的特征,初步探讨了在不同肥料作用下稀土元素和磷在土壤中迁移的关联性。结果表明,绝大部分稀土元素和磷素都是通过径流沉积物相流失;施入肥料的种类不同对稀土的影响也有差别,磷肥进入土壤后会影响土壤中稀土的化学行为及迁移,同一稀土元素的浓度在有机肥作用下相对较高;试验结果为开展利用稀土多素示踪方法解析粪肥面源来源的可行性研究提供了参考依据。

| Abstract: | Through artificial rainfall experiments,the loss of rare earth elements and P in the soil applying with different kinds of fertilizers was observed.And the association of migration with rare earth elements and P under different fertilizers in the soil was investigated.The results show that majority of rare earth elements and P transport with fine soil particles in runoff.The applied five types of fertilizers have different effects on the rare earth elements.Fertilizer types can significantly affect the chem... |
