植物需要大量营养素和微量营养素，每种营养素对于植物完成其生命周期都是必需的。充足的养分供应对植物生长影响很大，因此在农业中至关重要。植物根部以离子形式从土壤溶液中吸收矿物质，这是由特定的转运蛋白介导的。最近，在确定营养物质吸收和分配的运输和调节机制方面取得了重要进展。本章将讨论这一点以及每种营养素的主要生理作用。
Plants require macro- and micronutrients, each of which is essential for a plant to complete its life cycle. Adequate provision of nutrients impacts greatly on plant growth and as such is of crucial importance in the context of agriculture. Minerals are taken up by plant roots from the soil solution in ionic form which is mediated by specific transport proteins. Recently, important progress has been achieved in identifying transport and regulatory mechanisms for the uptake and distribution of nutrients. This and the main physiological roles of each nutrient will be discussed in this chapter.
