摘要: 为探究虾蟹混养池塘的温室气体排放规律及其影响因子,构建了中华绒螯蟹单养(Q1)和放养高(Q2)、低(Q3)密度罗氏沼虾的虾蟹混养系统,采用静态悬浮箱-气相色谱法测定这3个系统的温室气体[二氧化碳(CO2)、甲烷(CH4)和氧化亚氮(N2O)]排放通量,同时检测水质和气象指标,并对其进行相关分析。结果显示:Q1、Q2、Q3的CO2排放通量分别为-47.06~65.19、-36.57~118.10、-43.33~85.47 mg·m-2·h-1,CH4排放通量分别为0.07~4.47、0.05~0.21、0.04~2.81 mg·m-2·h-1,N2O排放通量分别为-0.005~0.019、-0.031~0.009、-0.017~0.014 mg·m-2·h-1。相关分析表明:水体的pH值是影响池塘CO2排放通量的主要环境因子,亚硝酸盐氮质量浓度是影响池塘CH4和N2O排放通量的主要环境因子。Q1、Q2、Q3的全球增温潜势(GWP)分别为348.61、209.29、226.81 g·m-2,单位产品增温潜势(UWP)分别为2 294.24、970.97、1 296.80 g·kg-1。综上,向中华绒螯蟹养殖池塘内放养罗氏沼虾,虽然会提高CO2排放通量,但会降低CH4排放通量,对N2O排放通量的影响较小,与中华绒螯蟹单养相比,虾蟹混养能提高经济效益,降低GWP和UWP。

Abstract:

In order to reveal the greenhouse gases emission and influencing factors in shrimp and crab mixed culture pond, Eriocheir sinensis monoculture system (Q1) and mixed aquaculture system with high (Q2) or low (Q3) stocking densities of Macrobrachium rosenbergii were constructed. The greenhouse gases (CO2, CH4 and N2O) emission flux in these systems were determined by the static suspension box-gas chromatography (GC), and the water quality and meteorological indicators were also measured and used for correlation analysis. The results showed that the CO2 emission flux of Q1, Q2 and Q3 was -47.06-65.19,-36.57-118.10,-43.33-85.47 mg·m-2·h-1, respectively; the CH4 emission flux of Q1, Q2 and Q3 was 0.07-4.47, 0.05-0.21, 0.04-2.81 mg·m-2·h-1, respectively; and the N2O emission flux of Q1, Q2 and Q3 was -0.005-0.019,-0.031-0.009,-0.017-0.014 mg·m-2·h-1, respectively. The pH value of water was the main environmental factor affecting CO2 emission flux in ponds, while the concentration of nitrite nitrogen in the water was the main environmental factor affecting the CH4 and N2O emission. Global warming potential (GWP) of Q1, Q2 and Q3 was 348.61, 209.29, 226.81 g·m-2, respectively, and the unit product warming potential (UWP) of Q1, Q2 and Q3 was 2 294.24, 970.97, 1 296.80 g·kg-1, respectively. In general, co-culture of Eriocheir sinensis and Macrobrachium rosenbergii increased CO2 emission flux, yet decreased CH4 emission flux, and had no significant impact on N2O emission flux. Compared with the monoculture of Eriocheir sinensis, the mixed aquaculture could improve the economic benefit and decrease the GWP and UWP.
