摘　　要：China is striving to achieve"carbon dioxide peaking"in 2030 and"carbon neutrality"in 2060.In addition to optimizing and upgrading the industrial structure and increasing industrial emission reduction,afforestation is an important way to increase forest carbon sinks and achieve carbon dioxide peaking and carbon neutrality.Improved seedlings are significantly better than general seedlings in terms of afforestation adaptability,growth and stress resistance.The use of improved varieties for afforestation can improve the quality of afforestation from the source.Although the growth cycle of economical tree species is short,and the carbon storage does not increase after directional cultivation,they significantly improve the quality and yield,and indirectly reduce carbon emissions compared with ordinary seedlings.Therefore,in agricultural and forestry production,the transformation and utilization efficiency of improved varieties should be improved and the planting structure should be optimized to improve the quality and efficiency and significantly improve the yield and carbon storage,and the management of plantations should be strengthened to help achieve the goal of"carbon neutrality"as soon as possible.This paper analyzed the current situation of improved varieties and plantation management in China,and put forward corresponding countermeasures.
