农田土壤对磷的吸附和解吸特性研究进展

Advances in Phosphorus Adsorption and Desorption of Farmland Soils

磷素是植物生长必需的三大营养元素之一,在植物生长发育过程中对植物的产量和品质有重要影响。综述了农田土壤对磷的吸附和解吸机制等方面的研究进展,分析土壤对磷的吸附和解吸影响因素,包括土壤类型、土地利用方式、施肥水平和土壤理化性质,旨在为实际生产中磷肥的合理施用、高效利用和防止环境污染提供依据。

Phosphorus was one of the three essential nutrients of plant growth.Phosphorus has important influence on yield and quality of plant.The research progress of phosphorus adsorption and desorption mechanism was reviewed in farmland soils.Influencing factors of phosphorus adsorption and desorption were analyzed,including soil type,land use,fertilization level,and soil physical and chemical properties.The aim was to provide basis for rational application and efficient utilization of phosphate fertilizer and prevention of environmental pollution in actual production.
