摘　　要：从育种、耕作与栽培三个方面分析了适应CO2肥效作用的农业技术潜力措施。在育种方面,采用综合运用育种理论和育种技术培育新品种,改善作物生理和生态性状来适应大气中CO2含量升高;在耕作制度上,采用调整作物播期、改变当前多熟制边界、调整水作和旱作作物、C3作物和C4作物的播种面积和区域布局等措施;在栽培措施上,采用调节作物冠层温度、改善灌溉条件、保持土壤肥力和养分以及综合防治病虫草害和极端天气灾害等综合措施。扬长避短,兴利除弊,采取主动适应CO2肥效作用的策略,最大限度发挥作物产量潜力。The agricultural technical potential and response measures adapted to CO2 fertilization effect in the perspective of crop breeding, cultivation and farming systems under climate change were summarized. New theories and technologies should be comprehensively applied in crop breeding to improve the eco-physical characteristics of crops, so as to adapt to the elevated CO2 concentration in the atmosphere; The following measures should be taken in farming systems to adapt the climate change： adjusting sowing period, changing cropping systems, adjusting crop distribution on dryland and irrigated land, and selecting C3 or C4 crop. Adjusting crop canopy temperature, improving irrigation conditions, maintaining water supply and nutrients in soil, and managing diseases, pests, weeds, and other extreme climate disasters should applied as comprehensive response measures in the perspective of crop cultivation.
