长期施肥条件下土壤磷素的研究进展

Advances in Phosphorus in Long-Term Fertilized Soil

施用磷(P)肥是提高农作物生产的重要措施。P肥施入土壤后易与土壤组分反应生成难溶的、对植物有效性低的化合物,因此P是土壤肥力管理中的一个重要方面。本文综述了国内外长期施肥条件下农田土壤P素的利用与积累状况、土壤P素形态转化及生物有效性的研究概况、长期施肥对土壤P素吸附与解吸的影响以及土壤P素流失的研究现状,并提出了目前在长期施肥条件下土壤P素的研究中存在的一些问题以及今后研究的热点。

Phosphorus is an important aspect of soil fertility management. This paper reviewed the latest research advances in the world about the utilization and accumulation of phosphorus nutrient, phosphorus form transformation and their bioavailability, phosphate adsorption-desorption characteristic and loss in long-term fertilized soil. The existent problems in this field and its hotspots in future were also discussed.
