摘要:

胶体在土壤磷素迁移中起重要作用.土壤胶体磷活化迁移对土壤磷库的变化和周围水环境质量产生影响.本文介绍了土壤胶体磷研究的相关进展,探讨了土壤理化性质、施肥、降雨、土壤改良剂等因素对胶体磷在土壤赋存迁移中的影响,分析了流场分离、电镜能谱、同步辐射X光近边吸收结构光谱和核磁共振等技术在胶体磷研究中的应用,以及降低胶体磷流失的方法,以期为胶体磷在土壤中赋存变化和迁移机制的研究提供重要信息.

 

Abstract: Colloids play a key role in the transference process of phosphorus (P) in soil. Activation and transference of soil colloidal phosphorus have great effect on soil P pool and the surrounding water quality. This paper summarized the current studies on soil colloidal P, discussing the effects of the various factors (e.g., soil physical and chemical properties, fertilization, rainfall and soil amendments) on the transference of soil colloidal P. Some advanced analysis technologies (e.g., flow fieldflow fractionation, transmission electron microscopeenergy dispersive Xray spectrometer, Xray absorption nearedge structure and nuclear magnetic resonance) and methods of reducing soil colloidal P were also involved. This review would provide important information on the mechanism of soil colloidal P transference.
