| 英文摘要 | Imbalanced nitrogen (N) and water management constrains the sustainable development of potato production in China. Although the 4R nutrient management strategy is crucial for optimizing potato production, water management is often overlooked in traditional 4R practices. Therefore, integrating N and water optimization is essential for enhancing potato production sustainability and safeguarding national food security. By integrating right irrigation into the established 4R nutrient stewardship framework, this study proposes an innovative 5R nutrient management strategy for potato production in China. A systematic review and meta-analysis of 139 studies were conducted to quantitatively evaluate the agronomic and environmental impacts of 5R-based practices, with focus on potato yield, N use efficiency (NUE), partial factor productivity of N (PFPN), irrigation water use efficiency (IWUE), and reactive N (Nr) losses. Our findings show that the optimal N application rate was approximately 200 kg N ha- 1 nationally, with significant regional variation accurately quantifiable via a nutrient expert system. Split fertilization (base fertilizer plus top dressing) significantly increases yield compared to basal application only, with the best results achieved by applying 25-50 % of the N fertilizer during the tuber development and bulking stages, respectively. The application of N fertilizer at a depth of 10-15 cm beside the plant significantly improves N use efficiency. The use of NH4+-N, enhanced-efficiency fertilizers (EEFs) and urea ammonium nitrate solution (UAN) increased yields by 16.6 %, 10.8 %, and 6.2 %, respectively, compared to conventional urea. Among these, nitrification inhibitors (NI), urease inhibitors (UI), combined application of NI and UI (NIUI), and polymer-coated urea (PCU) significantly boost potato yield and PFPN. Optimized irrigation methods (drip irrigation and sprinkler irrigation) compared to traditional furrow irrigation significantly increased yields by 19.0 %, improved IWUE by 139.8-148.6 %, and significantly reduced Nr losses by 23.3-51.6 %. This study proposed the 5R nutrient optimization management concept and framework for potatoes. By systematically quantifying the effects of different optimization measures on potato yield, NUE, and environmental impact, it provides a scientific basis for rational nutrient management and site-specific production practices in potato cultivation. |
