摘要： Straw returning to cropland is a sustainable management practices to enhance soil organic carbon (SOC) sequestration. The dynamics of straw C transformation in soils have been widely studied, however, it is less clear how crop planting regulates the incorporation of added straw C into SOC pools via soil - microbial nutrients status. We designed two sub- treatments, including single application of C-13-labeled straw (S) and its combination with crop planting (SR) in each fertilization treatment, and then conducted a field micro- experiment for 510 days. Regardless of fertilization, the SR treatments increased the content of straw derived mineral associated organic C (C-13-MAOC) by 53.19 % and that of straw- derived particulate organic C (C-13-POC) by 27.45 % compared with S treatments on the 510th day. And the SR treatments averagely increased the contribution percentage of straw-derived C in total MAOC by 39.44 %, especially under NP soil. Structure equation modeling results indicated crop planting promotes the formation of straw-derived SOC by reducing soil nutrients (r = -0.141, P < 0.05) and soil nutrients stoichiometry (r = -0.232, P < 0.01); fertilization alleviates nutrient limitations by reducing soil nutrients stoichiometry (r = -0.432, P < 0.001), microbial biomass stoichiometry (r = -0.701, P < 0.001), and increasing soil nutrients (r = 0.584, P < 0.001), thereby regulating the formation of straw C. Our results imply that crop planting contributes long-term incorporation of straw C to stable SOC pool via optimizing nutrients within soil-microbial system.
