摘要
在模拟田间条件下，采用静态吸收法和静态箱-气相色谱法对土壤NH3、N2O和CO2的排放进行测定，研究袋控肥对土壤氮素损失和综合温室效应的影响。结果表明：与普通复合肥相比，袋控肥能够显著延后和削减NH3、N2O和CO2日排放高峰，减少NH3、N2O和CO2的累积排放量52．17％～59．70％，48．57％～49．50％和23．49％～30．57％，减少土壤氮素损失56．04％，减少由N：0和CO。排放造成的温室效应潜势27．75％～28．63％。
By using static chamber-gas chromatographic and static absorption techniques, the NH3, N20 and CO2 emissions from the soil were measured under field simulation conditions. The effect of paper package fer- tilization on soil nitrogen loss and comprehensive greenhouse effect was studied. The results showed that the paper package fertilization could significantly reduce emission peak, and reduce accumulative emission by 52.17%-59.70%, 48.57%-49.50% and 23.49%-30.57%. It could reduce the loss of soil nitrogen by 56.04% and reduce global warming potential by 27.75%~28.63% caused by N2O and CO2.
