This study analyzed the current status of chemical fertilizer reduction and efficiency improvement work in Wuhu City, Anhui Province, as well as the key links requiring focused attention, and proposed future improvement paths. In the study area, the agricultural chemical fertilizer application rate in 2023 decreased by 16.20% compared with that in 2014, and the chemical fertilizer application intensity decreased by an average of 16.83 kg/hm2 per year from 2018 to 2023; the ratio of nitrogen (N), phosphorus (P), and potassium (K) has been optimized to 1:0.3:0.5, while promoting the combined application of macronutrients with medium and trace elements. The chemical fertilizer use efficiency has been improved to a certain extent, reaching 42% in 2023. However, the current chemical fertilizer reduction and efficiency improvement work still needs further improvement in aspects such as the application of soil testing and formula fertilization technology and data, the promotion degree and applicability of the integrated application of “Three News” (new technologies, new products, new machinery), the efficiency of conventional fertilization methods and the application of new technologies, and the implementation of the chemical fertilizer application quota system. In the future, the continuous optimization of fertilizer formulas and a significant improvement in fertilizer use efficiency can be further achieved through measures such as reasonably conducting field experiments on the application of new fertilizers and the combined application of organic and inorganic fertilizers to establish fixed channels for releasing fertilizer formulas; promoting mature integrated application models of “Three News” and selecting sample plots with good application effects; adopting methods such as side-deep fertilization and seed-fertilizer co-sowing to strengthen the integration of machinery and agronomy, and the integration of technology and materials; selecting representative regions to carry out demonstration and promotion of the chemical fertilizer application quota system, and strengthening technical training for ordinary growers. This study provides a reference for the further promotion of chemical fertilizer reduction and efficiency improvement work in the study area.
