摘　　要：针对当前我国农业生产面临增肥不增产、土壤养分过量累积、化肥施用过量和养分利用效率下降等重大问题,本文综述了中国土壤养分与植物营养状况的历史演变和研究进展,提出中国植物营养科学研究应在跟踪国际科学前沿的同时,紧密结合中国农业生产实际,通过大幅度提高养分效率和作物产量为农业可持续发展做出应有的贡献。Aiming at important challenges faced by Chinese agricultural production, including increased fertilizer application without yield increase, excessive soil nutrient accumulation, over-application of chemical fertilizers and declining nutrient use efficiency, this paper reviews the historical development and research advances into soil and plant nutrient management in China. It discusses the need for Chinese plant nutrition research not only to follow international cutting-edge research advances but also closely combine Chinese agricultural production practices to contribute to the sustainable development of agriculture by significantly improving both nutrient use efficiency and crop yield.
