摘　　要：采用静态箱-气相色谱法研究控失复合肥对稻田CH4排放量和水稻产量的影响。结果表明:稻田CH4排放有明显季节变化趋势,排放高峰集中在水稻分蘖期和孕穗期;控失复合肥的使用可减少稻田CH4累积排放量,控失复合肥较常规施肥在减N 24.21%、10.00%和增N 10.83%情况下分别减排CH4 64.97%、12.97%和15.06%;控失复合肥的使用可降低水稻单位产量的全球变暖潜能值(GWP);控失复合肥的使用对水稻增产具有显著作用。The effects of lose-controlled compound fertilizer on CH4 emission and rice yield in paddy field are studied by static box - gas chromatography under field experiment. The results show： CH4 emissions from rice field has obvious seasonal variation trend, the peak of CH4 emission gather in tillering stage and booting stage; The use of lose-controlled compound fertilizer can reduce the cumulative emissions of CH4 in rice fields, compared with the conventional fertilization treatment in the same period, lose-controlled compound fertilizer treatment can reduce the cumulative emissions of CH4 64.97, 12.97% and 15.06% respectively when decreases N 24.21%, 10.00% or increased N 10.83%; The use of lose-control compound fertilizer can reduce the global warming potential per unit weight yield of flee; The use of lose-controlled compound fertilizer has significant effect to rice yield increase.
