Aim of this study to review information on various aspects of P fertilization in rice i.e., P nutrition of rice, P response of rice plant, P availability in rice soils and P adsorption in rice soils for better understanding of P fertilization in rice culture. A substantial portion of the applied P along with the soil P is lost from rice fields to water bodies causing environmental pollution problems through eutrophication. These pollution problems can be minimized by using proper source of P as fertilizer, proper timing and methods of P fertilizer application, soil P management, transport management, use of plant growth promoting microorganisms which helps in efficient use of P by crops and use of green manure crops which improves soil fertility as well as helps in efficient use of P by crops.
本研究旨在综述水稻磷肥施用各方面的信息,即水稻的磷营养、水稻植株的磷响应、水稻土中的磷有效性和水稻土中的磷吸附,以便更好地理解水稻栽培中的磷肥施用。施用的磷以及土壤中的磷有很大一部分从稻田流失到水体中,通过富营养化造成环境污染问题。通过使用合适的磷肥源、合适的磷肥施用时间和方法、土壤磷管理、运输管理、使用有助于作物高效利用磷的植物生长促进微生物以及使用能提高土壤肥力并有助于作物高效利用磷的绿肥作物,可以将这些污染问题降至最低。
