Bioscience Methods 2025, Vol.16, No.4, 204-217 http://bioscipublisher.com/index.php/bm 216 intuitively understand the effect of reducing nitrogen without reducing production, and enhance their willingness to adopt green fertilization technology. The government can continue to implement soil testing and formula fertilization subsidies, green agricultural projects, etc., to guide new agricultural operators to participate in technology promotion. Finally, a long-term mechanism for nitrogen fertilizer management should be established, including the formulation of regional and variety-specific nitrogen fertilizer recommendation standards and regulatory measures to ensure the continued achievement of the goal of reducing nitrogen fertilizer use and increasing efficiency. Efficient use of nitrogen is a key link in the "win-win" situation of increasing grain production and protecting the environment. With the development of biotechnology and digital agriculture, we have reason to believe that through a combination of research and promotion, the level of rice nitrogen management will continue to improve in the future, helping grain production move towards higher yields, higher efficiency and more sustainable goals.
