Abstract Crop straw return is one of the most important measures to increase soil organic carbon (SOC) content in farmland systems. However, effects crop amount on SOC sequestration (SCS) long‐term rotation system unclear, especially typically cool and dry regions. A field experiment was conducted from 2015 2020 a wheat‐maize‐potato including four treatments: without incorporation (CK), 1/3 (LS), 2/3 (MS), all‐straw (HS), respectively. After 6 years cropping, SCS 0–30‐cm layer CK, LS, MS, HS increased by 3.6, 7.0, 7.8, 9.9 Mg ha −1 , compared with beginning experiment, In particular, 20–30‐cm CK obviously 2.7 . When total matter, evapotranspiration, SCS, water productivity 29.3%, 3.4%, 28.8%, 25.2% average, respectively, but decreased pure accumulation use efficiency sequestration. Although input showed linear positive correlation negatively correlated MS. 64.1% HS, restricting SCS. These results indicated that could as well decrease loss the–crop system, making it more suitable for application semiarid region, revealed excessively returning not improve efficiency.
