| 摘 要： | 采用静态箱-气相色谱法研究日光温室生菜地不施肥(CK)、施用腐熟鸡粪(H)、羊粪(S)、鸡粪+秸秆(HSt)、羊粪+秸秆(SSt)、羊粪+鸡粪+秸秆(SHSt)等6种处理的温室气体排放通量及增温潜势(GWP)。结果表明:(1)H、S、HSt处理的N_2O排放通量在施肥前、中、后期呈近"V"型变化,CK、SSt、SHSt呈倒"V"型变化;S、SSt、SHSt处理的CH_4排放通量呈倒"V"型变化;CO_2排放通量均呈近"V"型变化(SSt除外);(2)施肥前期,HSt、S、H、SHSt、SSt处理的N_2O排放通量分别较CK显著增加2.89、2.32、1.48、1.17、0.95倍;S、H的CH_4排放通量显著高于CK处理1.91、1.11倍;H的CO_2排放通量显著低于CK处理3.88倍。施肥中期,HSt的N_2O排放通量显著低于CK处理1.93倍;SHSt的CH_4排放通量显著高于CK处理1.34倍;各施肥处理的CO_2排放通量与CK差异不显著。施肥后期,H的N_2O排放通量显著高于CK处理1.10倍;SHSt、SSt、S的CH_4排放通量显著低于CK处理3.76、5.25、5.58倍;HSt的CO_2排放通量显著高于CK处理8.61倍;(3)全球增温潜势(GWP)按照SSHStHStSStCKH依次减小,建议施用腐熟鸡粪、鸡粪加秸秆及羊粪加秸秆。

| Abstract: | Emission flux of greenhouse gases (GHGs) and global warming potential (GWP) of asolarlettuce-greenhouse using organic fertilizers were studied.A decomposed chicken manure (H), a sheep manure (S), a chicken manure/straw combination (HSt), a sheep manure/straw combination (SSt), a sheep manure, or a chicken manure/straw combination (SHSt) wasapplied on the soil.The atmospheric conditions in the greenhouse with each fertilization were monitored using the static chamber-gas chromatograph techniques.The results showed that (1) throughout the entire fertilization period, the N2O emissionsfrom H, S and HSt were in a V-shapemathematicfunction, whileCK, SSt and SHSt, an inverted V-shape function;the CH4 emissionsfrom S, SSt and SHSt were inan inverted V-shape trend;and,the CO2 emissionsfrom all, except SSt,were in aV-shape;(2) during the early stage of the fertilizations, the N2O emissionsfrom HSt, S, H, SHSt and SSt were 2.89, 2.32, 1.48, 1.17 and 0.95 times, respectively,greater than that of CK;the CH4 emissionsfrom S and H, 1.91 and 1.11 times, respectively,greater than that of CK;and, the CO2 emission from H, 3.88 times lower than that of CK;and, in the middle of the fertilizations, the N2O emission from HSt was 1.93 times lower than CK;the CH4 emission from SHSt, 1.34 times greater than CK;and, no significant differences onthe CO2 emissionsbetween CK and all other treatments;whereas, at the late stage of the fertilizations, the N2O emission from H was 1.10 times greater than CK;the CH4 emissionsfrom SHSt, SSt and S, 3.76, 5.25 and 5.58 times, respectively, lower than CK;and, the CO2 emission of HSt, 8.61 times greater than CK;and, (3) GWP for the various fertilization treatments decreased in the order of S>SHSt>HSt>SSt>CK>H.Consequently, H, SSt,orHSt was recommended for farmingapplicationsin light of their potentials in GHG emission reduction. |
