摘要: Carbon sequestration and emission reduction in apple cultivation are of great signifcance for achievingsustainable agricultural development and combating climate change. However, the status ofcarbonemissions from apple cultivation is unclear, and this study will provide implications for the agriculturesector. This study applied the life cycle assessment method to quantify carbon emissions and analysedthe footprint composition of apple orchards in China, and identifed the emissions peak based on theMann-Kendall analysis. The results showed that the carbon emissions of apple cultivation reachedthe carbon peak in 2014. The carbon emissions per unit area (CEA) and per unit yield (CEY) were 5.79t CO,eq ha- and 0.23 kg CO,eq kg- in 2021, respectively, Carbon emissions from fertilizers (54.4%)and irrigation electricity (30.9%) were identifed as the dominant components in apple orchards.Specifcally, Henan and Shandong exhibited higher growing advantages, characterized by highercarbon economic effciency and lower CEY, The carbon emissions of the ideal scenario will be decreased69.6% through optimizing fertilizers and energy restructuring. In conclusion, promoting low-carbondevelopment in apple orchards can be achieved through targeted in-feld mitigation measures, such asoptimizing the amount and types of fertilizers, and adopting new energy for agricultural machinery.
