本研究对山东滕州和兖州的施肥状况进行入户调查，借鉴农田管理措施的固碳速率和温室气体（GHG）排放的计算方法，根据农业部的施肥建议设定不同推荐情景，估算施肥现状和推荐情景对GHG净排放和经济成本的影响。结果表明，小麦和玉米都采用推荐用肥能明显减少GHG排放和经济成本，特别是玉米采用基追结合，滕州和兖州的排放分别减少300 kgCe/（hm2·a），成本减少2700元/hm2，化肥碳效率增加超过30％。总之，农业部施肥建议的推广应用具有重要的环境和经济价值。

The investigation on fertilization status was carried out in Tengzhou and Yanzhou,Shandong Province.Different recommended scenarios were made,and their impacts on GHG net emission and economic cost were studied and compared to fertilizing status by the calculation methods of carbon sequestration rate and GHG emission in farmland management.The results implied that the application of recommended fertilizers on wheat and corn could decrease GHG emission and economic cost.Especially the integrated application of base fertilizer and topdressing on corn,the GHG emission both decreased by 300 kgCe/(hm2 ·a)in Tengzhou and Yanzhou,the cost decreased by 2 700 yuan per hectare,and the carbon efficiency increased by more than 30%.In conclusion,the popularization and application of fertilizer recommended by the Ministry of Agricul-ture would have important environmental and economical values.
