摘　　要：【目的】研究猪粪与菌剂配施对山地红壤温室气体排放的影响,为减少温室气体排放提供理论依据。【方法】通过盆栽试验,探讨对照(CK)、复合肥(F)、猪粪(FM)、低量菌剂与猪粪配施(FMI1)、中量菌剂与猪粪配施(FMI2)和高量菌剂与猪粪配施(FMI3)6种不同处理下土壤温室气体的排放规律。【结果】(1)施用菌剂可以显著降低CO2、CH4和N2O的排放通量,且高量菌剂与低中量菌剂有显著差异性;(2)高剂量菌剂与CK相比,CO2累计排放量降低了84.33%,CH4累计排放量降低了76.39%,N2O累计排放量降低了86.44%;(3)施用菌剂可以显著降低综合温室效应(GWP),菌剂施用量越大,对温室效应抑制越明显;(4)施用菌剂可以显著提高土壤养分含量。【结论】在施用肥料的基础上配施菌剂,可以降低山地红壤CO2、CH4和N2O排放通量与综合温室效应,且菌剂剂量越大,效果越佳。【Objective】 Effect of addition of a bacterial agent to pig manure or a compound fertilize in mountain red soil on the greenhouse gas emissions was investigated. 【Method】 In a pot experimentation on the red soil from hilly regions, a compound fertilizer(F), pig manure(FM), combination of FM and a low level bacterial agent(FMI1), combination of FM and a medium level bacterial agent(FMI2), or combination of FM and a high level bacterial agent(FMI3) was applied to examine the differences on the greenhouse gas emissions. 【Result】 The addition of the bacterial agent resulted in(1) a reduction on the emission fluxes of CO2, CH4 and N2O with a significant difference between the high level and the low or medium level of the application;(2) an 84.33% decrease on the cumulative CO2 emission, 76.39% on CH4, and 86.44% on N2O over CK;(3) a significantly reduced comprehensive greenhouse effect(GWP) which was enhanced with increasing addition level;and,(4) a significant improvement on the nutrient content in the soil. 【Conclusion】 Applying the bacterial agent along with pig manure or a compound fertilizer significantly reduced the emission fluxes of CO2, CH4 and N2O from the mountain red soil and GWP.The higher the dose of the bacterial agent, the greater beneficial effects would result.
