摘　　要：在吉林省中部农区梨树进行了化肥不同用量条件下玉米秸秆还田对土壤碳排放影响的田间试验研究。结果表明,玉米秸秆还田配合减量化肥可以在保证农作物产量的前提下,达到减少碳排放量的目的,且收获后每公顷平均碳排放量比正常耕作土壤降低20.1kg/d,是一种既经济又环保的耕作模式。Effect of putting the corn stalks on the black land on carbon emissions under different level of chemical fertilizer was carried out in Lishu County of central part of Jilin Province.The results showed that putting the corn stalks on the black land accompany with reduction of chemical fertilizer could realize reduction of carbon emission on condition of keeping high level of crop production.It was not only economical but also environmental,and the carbon emission per hectare was reduced by 2.01 kg/d than the normally farmed soil after harvests.

关 键 词：秸秆还田 碳排放量 土壤呼吸
