植烟土壤有机氮矿化及影响因素研究进展OA

The mineralization of soil organic nitrogen plays a crucial role in enabling crop uptake and utilization of nitrogen.Therefore,in-depth research on the nitrogen mineralization patterns and influencing factors of tobacco-growing soils across different regions is of significant importance for precisely regulating soil nitrogen supply during the growth period of flue-cured tobacco,aligning it with the nitrogen demand characteristics of high-quality flue-cured tobacco,and ultimately promoting robust plant growth and the production of high-quality tobacco leav-es.A systematic review was conducted on the process and mechanism of soil nitrogen mineralization.The effects of soil properties,environmen-tal conditions,and organic fertilizer application were also discussed.Furthermore,potential future research directions are proposed to provide theoretical support for the rational use of nitrogen fertilizers in tobacco cultivation.
