【Objective】The objective of this paper was to explore the emission characteristics and warming potential of the greenhouse gases N_2O, CO_2 and CH_4 from table grape vineyard soils under different water and nitrogen regulation, and to understand the contribution of water and nitrogen regulation to greenhouse gas emissions, thus screening out a more reasonable management model of water and nitrogen regulation, so as to provide scientific basis and technical reference for reducing greenhouse gas emissions from vineyards and promoting grape industry sustainable production. 【Method】From April 2017 to December 2017, Changli, the main grape producing area in Hebei Province, was selected as the experimental site and the table grape Red globe was used as the tested grape variety. A field microplot experiment was employed with four treatments, including traditional water and nitrogen, mobile water and fertilizer, optimized water and nitrogen, as well as optimized water and nitrogen + DMPP. The greenhouse gas emissions (N_2O, CO_2 and CH_4) from the vineyard soil were monitored by using closed static chamber-gas chromatography, and then their comprehensive warming potential differences were compared. Final, the grape yields were measured. 【Result】N_2O emission flux showed a single peak trend after fertilization, and the peak appeared on the 1-2 day after fertilization. Nitrogen fertilizer could significantly increase soil N_2O emission flux. Compared with the traditional water and nitrogen treatment, nitrogen reduction and water control treatments could reduce the average N_2O emission flux by 73.03%-88.19%, and their difference was significant (P<0.05). Optimized water and nitrogen + DMPP treatment could reduce the N_2O emission flux by 50.08% on average under the condition of equal nitrogen, and the trend of CO_2 emission flux was the same in all treatments, reaching the peak 2-3 days after fertilization, showing seasonal variation in the growth period. Nitrogen reduction and water control treatments could reduce CO_2 emissions by 60.56%-62.13%. CH_4 emission flux had no obvious change trend, but CH_4 emission flux was positive or negative after fertilization. The traditional CH_4 emission flux fluctuated greatly, ranging from -0.132 to 0.238 mug·m~(-2)·h~(-1). There was no significant difference between nitrogen reduction and water control treatments (P>0.05). During the whole experiment period, the total N_2O emissions of the treatments were in the order of traditional water and nitrogen, optimized water and nitrogen, mobile water and fertilizer and optimized water and nitrogen+DMPP, which were 3.90, 2.83, 2.76 and 2.65 kg·hm~(-2) with the emission coefficients were 0.58%-0.67%, respectively. Comparing with traditional water and nitrogen treatment, the nitrogen reduction and water control treatments (mobile water and fertilizer, optimized water and nitrogen and optimized water and nitrogen+DMPP) could reduce the total N_2O emissions by 27.56%-32.09%.
