| 英文摘要 | N2O and NO emissions, the water usage and grain yields of a maize field in the North China Plain (NCP) under traditional flood irrigation, drip irrigation and drip fertigation were compared. With respect to the flood irrigation treatment, N2O emissions were reduced by 13.8% in the drip irrigation treatment and 7.7% in the drip fertigation treatment. NO emissions were reduced to 16.7% in the drip irrigation treatment but increased by 21.7% in the drip fertigation treatment. The molar ratios of NO/N2O within 2 days after each fertilization event were evidently greater from the drip fertigation treatment than from the flood irrigation treatment, indicating that nitrification was more intensive in the drip fertigation treatment than in the treatment of flood irrigation. Compared with the flood irrigation treatment, evident increase of the maize yields in the drip irrigation treatment (28%) and the drip fertigation treatment (3.7%) were found. Although the drip fertigation treatment could evidently increase NO emission, the 40% water reduction in drip fertigation is of great importance for the sustainable development of agriculture in the NCP where water resources are extremely limited. To mitigate NO emissions from agricultural fields in the NCP with drip fertigation, the addition of a nitrification inhibitor combined with N or nitrate fertilizer was recommended.
