土壤-作物系统氮素损失行为及高效利用的研究进展

摘要

根据国内外研究概况，综述了土壤-作物系统中主要氮素损失途径，作物高效吸收、利用氮素的生理生态机制及调控作物高效利用氮素的最新理论与方法，以期为实现氮素高效利用提供理论依据。%According to the relevant research works conducted in the world in recent years , this article summarized the main ways of nitrogen loss in soil -crop system, the physiological and ecological mechanisms of nitrogen high -efficient uptake and utili-zation by crop, and the newest theories and methods for increasing the high -efficient utilization of nitrogen by crop .The objective of this paper was to provide theoretical basis for the high -efficient nitrogen utilization.
