| 英文摘要 | The frequency of droughts and floods has increased due to climate change and human activities, leading to adverse impacts on agricultural production. Conventional tillage exacerbates the vulnerability of crops to extreme weather. Optimized tillage practices can maintain crop yield stability by increasing soil water -holding capacity during dry seasons and improving crop lodging resistance during heavy rainfall events. The effects of tillage practice under different rainfall types on the productivity of summer maize were studied by combining a five -year field experiment and a meta-analysis. The study tested four tillage treatments: conventional tillage (CT), no-tillage (NT), ridge cultivation with no-tillage (RNT), and winter wheat conventional tillage followed by summer maize no-tillage (NC). Normal rainfall years (2018, 2019 and 2021), a wet year (2020), and a drought year (2022) were experienced during the experiment. Compared to CT, NC significantly increased available soil water storage during the dry season by an average of 19.7 % (P < 0.05). NC and RNT had lower lodging rates during the wet year than CT, and over the five years, NC had a higher average maize yield (9.8 t ha( -1)) than RNT, while RNT had a higher yield during the wet year (10.7 t ha( -1)). NC also had significantly higher yield stability than CT. Furthermore, NC and RNT had higher rainwater use efficiencies (RUE) (23.9 and 23.0 kg ha (-1) mm (-1), respectively) than NT and CT (22.9 and 21.6 kg ha( -1) mm( -1), respectively). A meta-analysis showed that the crop yield under combined tillage (COT) was significantly higher than CT and NT by 6.7 % and 7.1 %, respectively, confirming the reliability and universality of the field experiment results. Overall, NC rotation is recommended as the best tillage system for sustainable crop production under semi -arid conditions, while RNT can be used in areas with abundant rainfall and prone to flooding. Our research findings offer evidence-based insights into management strategies that can enhance agricultural ecosystem resilience and production stability under extreme climate conditions. |
