作物水氮耦合对农田土壤环境的影响

作物所处的土壤环境对提高作物产量和品质至关重要。为深入研究土壤生产力可持续发展提供理论依据，迫切需要了解现阶段作物水氮耦合效应对土壤环境的影响，重点总结了作物水氮耦合效应对土壤容重、孔隙度、含水量、温度、养分、有机质、酶活性、微生物和气体排放等土壤环境的影响，并提出未来水氮耦合的重点研究方向，以期为土壤的高效生产和可持续利用提供理论依据。 

Effects of crop water and nitrogen coupling on field soil environment

The soil environment in which crops are grown is crucial for improving crop yield and quality. In order to understand the progress of research on the effects of crop water and nitrogen coupling on the soil environment and to provide a theoretical basis for future in-depth research on the sustainable development of soil productivity, this paper focuses on summarising the results of the effects of crop water and nitrogen coupling on the soil environment such as soil bulk, porosity, water content, temperature nutrients, organic matter, enzyme activity, microorganisms and gas emissions , and proposes future research directions for water and nitrogen coupling, with a view to providing a theoretical basis for efficient soil The results also suggest future research directions for water-nitrogen coupling, with a view to providing a theoretical basis for efficient soil production and sustainable use.
