摘要: Water management and nitrogen (N) fertilizers are the two main driving factors of greenhouse gas emissions. In this paper, irrigation modes, controlled (CI) flood (FI), four fertilizer levels (N0: 0, N1: 85, N2: 110, N3: 135 kg·hm−2) were set to study effect different modes N amount on greenhouse-gas emissions paddy fields in cold region by using static chamber-gas chromatograph method; yield water consumption also analyzed. The results showed that, compared with FI, CI significantly reduced CH4 19.42~46.94%, but increased N2O 5.66~11.85%. Under could increase emissions, each treatment few differences. Compared appropriate application under grain number per spike, seed-setting rate, 1000-grain weight, thus increasing yield. total was lower than that FI. global warming potential (GWP) smaller trend GWP similar CH4. Through comprehensive comparison analysis productivity (WP), emission intensity (GHGI), treatment, we found CI+N2 had highest WP (2.05 kg·m−3) lowest GHGI (0.37 kg CO2-eq·kg−1), while maintaining high (10,224.4 kg·hm−2). provide an important basis for guiding yield, water-savings, reduction regions.
