摘要： Root carbon (C) investment in exchange for phosphorus (P) is a pivotal nutrient acquisition strategy that profoundly impacts soil biogeochemical processes and maintains the functional stability of rice paddy ecosystems. However, the response patterns of C cost-P benefit strategies to external nitrogen (N) input in rice paddies remain unclear. Therefore, root C exudation rates were repeatedly measured using an in situ collection method under control, low N (100 kg ha-1), and high N (200 kg ha-1) treatments. Additionally, soil properties and root morphology were analyzed to identify the main factors influencing variations in root exudation. The results showed that root C exudation rates under high N application increased by 55.1 % compared to the control. These differences were primarily linked to N-induced changes in soil P availability, root biomass, root length, root surface area, and root volume. Consequently, understanding the interplay between soil nutrient availability and root exudation is crucial for optimizing fertilization strategies and improving nutrient use efficiency in rice cultivation systems.
