Abstract：Facing the increasingly complex international environment and the need for the construction and development of ecological civilization, China has promised to achieve carbon neutrality by 2060. Vigorously promoting the improvement of the quality of arable land in medium and low-yield fields and building high-standard farmland are effective ways to increase grain production capacity and achieve agricultural carbon neutrality. The sources of carbon emissions and the potential of emission reduction in the agricultural field are analyzed, and the result and shows that the agricultural system has great potential for carbon sequestration and emission reduction through scientific and reasonable technologies to improve the quality of cultivated land and optimize field management. Combined with the advanced carbon emission reduction measures that adopted internationally, it is proposed that under the background of agricultural carbon neutrality, China needs to focus on ″reducing the difference in crop yield and efficiency to ensure food security″, ″reducing the energy consumption of nitrogen fertilizer production and improving nitrogen fertilizer use efficiency″, ″inhibiting the Methane emissions from paddy fields, promoting low-carbon rice farming technologies″ and ″increasing the return of rotted straw to the field, and optimizing the fertilizer management model″ and other measures to improve the quality of cultivated land. The necessary suggestions for carbon neutrality in China′s future agricultural field, in order to provide necessary reference for accelerating the improvement of cultivated land production capacity and realizing carbon sequestration, is put forwarded.
