摘要:

为探索二氢卟吩铁和不同类型地膜覆盖菜地的综合温室效应,以西蓝花‘耐寒优秀’为供试品种,通过田间试验,设置清水+塑料地膜覆盖(CK)、二氢卟吩铁+塑料地膜覆盖(T1)和二氢卟吩铁+全生物降解地膜覆盖(T2) 3个处理,采用静态暗箱—气相色谱法对菜地的CH4、N2O、全球增温潜势(GWP)和温室气体排放强度(GHGI)进行分析。结果表明:相较于CK,T2显著减少了59.4%的CH4吸收量和25.6%的N2O排放量,CH4排放量与水溶性有机碳和微生物生物量碳呈显著正相关,N2O排放与NO3--N呈显著正相关,而与DOC呈显著负相关。与T1相比,T2显著增加了22.9%的西蓝花产量,显著减少了37.8% 的GWP,GHGI在T2处理下比CK和T1分别显著减少40.0%和50.0%。研究显示,覆盖全生物降解地膜条件下喷施二氢卟吩铁具有增产减排效果,可作为一种低碳技术模式推荐使用。

Abstract:

To explore the comprehensive greenhouse effect of iron chlorine e6 and different types of plastic film mulching, this study conducted a field experiment, setting up three treatments: water + plastic mulching (CK), iron chlorine e6 + plastic film mulching (T1), and iron chlorine e6 + biodegradable film mulching (T2). Static chamber gas chromatography was used to analyze CH4, N2O, global warming potential (GWP) and greenhouse gas emission intensity (GHGI) in a vegetable field. The results showed that compared to CK, T2 significantly reduced CH4 absorption by 59.4% and N2O emissions by 25.6%. CH4 emission was significantly positively correlated with dissolved organic carbon and microbial biomass carbon, while N2O emission was significantly positively correlated with NO3--N and negatively correlated with DOC. Compared with T1, T2 significantly increased broccoli yield by 22.9%, significantly reduced GWP by 37.8%, and GHGI significantly decreased by 40.0% and 50.0% under T2 treatment, respectively, compared to CK and T1. In summary, it could be seen that the combination of iron chlorine e6 and biodegradable plastic film has an increase in production and emission reduction effect, and thus, can be recommended as a low-carbon technology model.
