前人研究表明按单位产量计算温室气体排放量比按单位面积,能更好的综合评价作物种植方法对温室气体排放的影响,对于种植方法的选择具有非常强的指导意义。本研究采用Meta定量分析了水稻基本苗对单位产量温室气体排放的增温潜势的影响。结果表明不同基本苗间单位产量温室气体排放的增温潜势存在显著差异。最低的单位产量温室气体排放的增温潜势的基本苗为80-100万苗/hm2。不同品种的温室气体排放增温潜势依次为杂交稻品种（1 028.86 kg CO2 equiv/mg）,常规稻品种（634.15 kg CO2 equiv/mg）和超级稻品种（576.57 kg CO2 equiv/mg）。因此,在基本苗为80-100万苗/hm-2的前提下,种植常规稻和超级稻...

Many researches showed a comprehensive assessment of the cropping practice effect on greenhouse gas (GHG) emissions per unit yield (yield-scaled) rather than per the land area (area-scaled), and it was noteworthy that cropping practices decided to increase or decrease grain yield, and reduce or promote greenhouse gas emissions. In this study, a meta-analysis was conducted to quantify the effects of rice basic seedlings (BS) on the global warming potential (GWP) of GHG emissions at the yield-scale in China. The results suggested that significant difference was observed in yield-scaled GWP of BS...
