Determining the appropriate nitrogen application rate for Ficus hirta Vahl. is one of the key cultivation techniques for establishing an efficient and ecological "rubber-Ficus hirta Vahl." agroforestry system. This study evaluated five nitrogen application treatments, 0, 150, 225, 300 and 375 kg/hm² (denoted as CK, N₁₅₀, N₂₂₅, N₃₀₀ and N₃₇₅), and conducted a comprehensive analysis of the suitable nitrogen rate from the perspectives of productivity, resource use efficiency, and ecological footprint. The results showed that, compared with the CK treatment, nitrogen application significantly increased the yield, biomass, and economic benefits. Among the treatments, N₂₂₅ and N₃₀₀ performed the best, achieving a yield of 15 438 and 15 150 kg/hm² and an economic benefit of 60 950 and 57 555 yuan/hm², respectively (P<0.05). Compared with CK, nitrogen application significantly improved solar utilization efficiency by 59.1%-76.9%, but significantly reduced carbon efficiency by 46.2%-73.7%. The partial factor productivity from applied nitrogen also decreased significantly with increasing nitrogen application (P<0.05). N₁₅₀ exhibited the best overall performance in resource use efficiency, followed by N₂₂₅. Similarly, N₁₅₀ showed the best overall performance in terms of carbon and nitrogen footprints, followed by N₂₂₅. Nitrogen uptake in Ficus hirta Vahl. across different treatments ranged from 117.8 to 174.0 kg/hm², with the CK and N₁₅₀ showing higher nitrogen uptake than nitrogen input. Taking into account the productivity, resource use efficiency, ecological footprint and sustainability of nitrogen supply, this study concludes that N₂₂₅ is the suitable nitrogen application rate for establishing an efficient and ecological "rubber-Ficus hirta Vahl." agroforestry system.

明确五指毛桃适宜施氮量是构建高效生态的“橡胶-五指毛桃”模式关键种植技术。本研究设置0、150、225、300、375 kg/hm² 5个施氮水平（分别记为CK、N₁₅₀、N₂₂₅、N₃₀₀、N₃₇₅），从间作五指毛桃的生产力、资源利用效率及生态足迹角度综合分析其适宜的施氮量。结果表明：与CK相比，施氮显著提高了五指毛桃的产量、生物量与经济效益，其中N₂₂₅和N₃₀₀处理的综合表现最好，产量分别为15 438、15 150 kg/hm²，利润分别为60 950、57 555元/hm²（P<0.05）。与CK相比，施氮能显著提高光能利用率，增幅为59.1%~76.9%，但显著降低碳效率，降幅为46.2%~73.7%，氮肥偏生产力也随施氮量增加而显著降低（P<0.05），N₁₅₀处理的资源利用率综合表现最好，N₂₂₅处理次之。N₁₅₀处理的碳足迹和氮足迹综合表现最好，N₂₂₅处理次之。各处理五指毛桃的氮吸收量为117.8~174.0 kg/hm²，其中CK和N₁₅₀处理的氮吸收量高于氮投入量。综合考虑生产力、资源利用率、生态足迹和氮素供给可持续性，本研究得出N₂₂₅处理为适宜的施氮处理，是构建高效生态的“橡胶-五指毛桃”模式的合理措施。
