摘要： Cropping systems in the future will need to increase grain yield while reducing greenhouse gas emission per unit, of production. Based on the investigation data of the farmer's production, applying carbon cost model, we conducted the carbon cost of rice on state-operated farm(13 production teams) in Northeast China Plain. The results were as follows: the carbon cost of rice on Shuanghe Farm was 221.62 +/- 26.32 gCO(2)e kg(-1), in which irrigation accounted for 40.68%, chemical fertilizer accounted for 24.55%, mechanical operation accounted for 24.35%, seed accounted for 9.21%, and pesticides accounted for 1.20%, respectively. The carbon cost of rice in different production teams were significantly different(P < 0.01), and 20th production teams was the highest (249.56 +/- 26.68 gCO(2)e kg(-1)) while 10th team was the lowest (190.87 +/- 17.09 gCO(2)e kg(-1)). The differences of the carbon cost of rice among production teams almost was resulted from irrigation, and it had the potentiality of emission reduction in the production teams with higher carbon cost.
