摘要
In response to the limitations of traditional double rice cropping models, this study constructed five typical rice planting models in the middle reaches of the Yangtze River, namely "Chinese milk vetch-early rice-late rice (CK/CRR), Chinese milk vetch-early rice-sweet potato || late soybean (CRI), rapeseed-early rice-late rice (RRR), rapeseed-early rice-sweet potato vertical bar vertical bar late soybean (RRI) and potato-early rice-late rice (PRR)" to study the annual emission characteristics of greenhouse gases under different planting models. The results showed the following: (1) From the perspective of total yield in two years, the CRI treatment reached its maximum, which was significantly higher than that of other treatments by 9.30 similar to 20.29% in 2019 (p < 0.05); in 2020, except for the treatment of RRI, it was significantly higher than other treatments by 20.46 similar to 30.23% (p < 0.05). (2) The cumulative emission of CH4 in the double rice treatment is generally higher than that in paddy-upland rotation treatment, while the cumulative emission of N2O in the paddy-upland rotation treatment is higher than that in the double rice treatment, but the total amount is much lower than the cumulative emission of CH4. Therefore, CH4 emissions from rice fields still occupy most of the GHGs. (3) The global warming potential (GWP) and greenhouse gas emission intensity (GHGI) of different planting patterns in rice fields in 2020 were higher than those in 2019, and the GWP and GHGI of double rice cropping treatment is higher than that of paddy-upland rotation treatments. During the two years, the GWP of CRR treatment reached its maximum and was significantly higher than that of other treatments by 48.28 similar to 448.90% and 34.43 similar to 278.33% (p < 0.05). The GHGI of CRR was significantly higher than that of CRI and RRI by 3.57 similar to 5.4 and 1.4 similar to 3.5 times (p < 0.05). Based on the comprehensive performance of greenhouse gas emissions over the two experimental years, RRI and CRI have shown good emission reduction effects, which can significantly reduce greenhouse gas emissions from paddy fields, are conducive to reducing global warming potential and greenhouse gas emission intensity and conform to the development trend of "carbon neutrality". Therefore, considering high-yield, low-temperature chamber gas emissions, the Chinese milk vetch-early rice-sweet potato vertical bar vertical bar late soybean model performs well and has the best comprehensive benefits. It is of great significance for optimizing the rice field planting mode in the middle reaches of the Yangtze River.
