摘要
氮肥对提高农作物的产量具有重要作用,但过量施氮不仅会影响作物产量和品质,还会对生态环境产生负面影响,而适当减量施氮,既能保证作物产量、提高肥料利用率,又能减少对环境的危害,从而实现农业高产、高效、持续健康的发展。本文综述了氮肥减量施用技术及其对农作物产量和生态环境影响的最新研究进展,提出了减量施肥过程中存在的问题及展望,旨在为保证作物高产和兼顾环境友好的氮肥减量施用技术提供思路和参考。
Nitrogen fertilization plays an important role in crop yield. However,excessive nitrogen fertilization not only negatively affects crop yield and quality,but also has a detrimental impact on the environment. Instead,appropriate reductions in nitrogen fertilization can guarantee crop yields,improve fertilizer use efficiency,and reduce the harm to the environment,therefore achieving a sustainable form of high-yield and high-efficiency agriculture. This paper reviewed the latest research on nitrogen fertilizer reduction technology along with its effects on crop yield and the ecological environment,and proposed the issues and prospects surrounding this process,so as to provide comprehensive insights into nitrogen fertilization reduction while maintaining high yield and environmental friendliness.
