Cropland soil is one of the major sources of greenhouse gas N2O generation and emission, and it is of important significance for reducing the generation and emission of N2O to study on the main influence factors of N2O emissions from cropland soil. Based on a large number of literatures, this paper has reviewed the mechanism and the influencing factors of the N2O emissions, particularly on soil physicochemical characters and cultivation management; found that reducing agricultural N2O emissions needs the corresponding reasonable tillage management in the process of agricultural production base...
