| 英文摘要 | Tillage and straw return practices substantially influence crop productivity and soil organic carbon (SOC) sequestration, yet their interactive effects remain poorly understood. Here, a 7-year field experiment was conducted in the North China Plain to evaluate the combined impacts of conventional tillage (CT) versus no-tillage (NT) and straw return (SR) versus no straw (NS) on crop yields and SOC stabilization in a wheat-maize rotation. Results showed that the combination of conventional tillage and straw return (CTSR) significantly improved both wheat and maize yields, with crop-specific responses. Wheat yields and sustainable yield index (SYI) benefited more from CT (+7.1 % and +83.3 %), whereas maize yields and SYI responded more to SR (+11.4 % and +11.0 %). The SOC under the CTSR treatment was the highest, with SR contributing more substantially than CT (30 % vs. 12 %). Despite potential disruption of soil structure, CT promoted SOC storage by enhancing nutrient availability and microbial activity. SR directly increased SOC through continuous organic input, aggregate stabilization, and enrichment of labile and stable carbon pools. However, CTSR also intensified soil microbial carbon and phosphorus limitations, potentially constraining microbial carbon use efficiency and long-term SOC stabilization. Structural equation modeling revealed that soil nutrients, aggregation, and carbon lability exerted positive and synergistic effects on both SOC stabilization and crop yields, whereas microbial resource limitations showed negative total effects. These findings underscore the need for integrated tillage and straw return strategies tailored to crop types and soil processes to enhance both productivity and long-term carbon sequestration. |
