土壤磷(P)的管理仍然是全球农业和自然生态系统经济和环境可持续性的关键问题。因此，我们必须对植物从土壤中获得磷的机制有适当的了解。在本章中，概述了促进土壤中磷的利用和获取的各种植物过程和生理特性，并讨论了将这些特性应用于农业种质的一些可能性。更好地了解这些过程和开发改良的种质可能最终提高农业系统的磷利用效率，并为更广泛的土地和资源管理提供有价值的信息。然而，目前很明显，与植物磷营养相关的基因与基因和基因与环境相互作用的复杂性还没有得到很好的认识。因此，重要的是继续制定系统的磷管理办法，以实现更可持续的农业。
Management of soil phosphorus (P) remains a crucial issue for the economic and environmental sustainability of agriculture and natural ecosystems globally. It is therefore essential that we have appropriate understanding of the mechanisms by which plants are able to acquire P from soil. In this chapter, various processes and physiological traits of plants that facilitate the availability and acquisition of P from soil are outlined, and some possibilities for deploying these traits into agricultural germplasm discussed. Better understanding of these processes and the development of improved germplasm may ultimately improve the P-use efficiency of agricultural systems and provide valuable information for wider-scale land and resource management. However, at present it is evident that the full extent of the complexity of the gene-by-gene and gene-by-environment interactions that are associated with plant P nutrition are not well appreciated. It is therefore important that a systems approach to P management continues to be developed for a more sustainable agriculture.
