【Objective】It is well known that the issue of greenhouse gases (GHGs) emission from rice ecosystem has been concerned within the scope of climate change research over years. The effect of controlled release fertilizer and additive treatments on GHGs emission and rice yield in a double rice (Oryza sative L) field was investigated to evaluate their potential of GHGs reduction and yield promotion, this study is also very important for the development of low-carbon agriculture and the mitigation research of global warming.【Method】Taking the double rice in Jianghan Plain, Hubei province, Central China as the object, a continuous observation of greenhouse gas emission from six different controlled release fertilizer or additive treatments(CK: conventional urea, CRU1: sulfur-coated urea, CRU2: polymer-coated urea, CU: nitrapyrin crystal urea, DMPP: nitrification inhibitor, EM: effective microorganisms) was conducted by using the automatic static chamber-GC (gas chromatography) method, the rice yield and soil properties were also monitored simultaneously. Variation and characterization of GHGs (CH_4 and N_2O) emission, greenhouse effect (CO_2-e) and greenhouse gas intensity of each treatment were analyzed comprehensively.【Result】The results indicated that CH_4 and N_2O emission in different fertilizer treatments had an obvious daily and seasonal variation law in double rice ecosystem. Controlled release urea (polymer-coated) caused the lowest CH_4 emission during the early rice, while the nitrapyrin crystal urea had the lowest CH_4 emission during the late rice growing season. In consideration of N_2O, the DMPP had the lowest emission during the two rice growing season compared to the other field applications. Pronounced differences were discovered among 6 treatments on global greenhouse effect (CO_2-e,on 100 a horizon) during the whole rice growing season(P<0.05). Among the field applications, CRU1 had the lowest global greenhouse effect, followed by CU, EM, DMPP, CRU2, and CK, respectively. Furthermore, significant greenhouse effect reduction potential was also employed; the polymer-coated urea dominated the fashion with the highest reduction potential of 56.2% compared to traditional fertilization, followed by nitrapyrin crystal urea (45.6%). In the view of rice yield, five other treatments were significantly higher than CK during late rice(stimulated rice yield by 13.5%-16.2%) while no statistical differences were found during early rice. Additionally, GHGI of polymer-coated urea was statistically lower than the other applications including the conventional fertilization (P<0.01).【Conclusion】Various reduction potential and yield promotion effects existed among different field applications from the double rice cropping system, this influence was significant during the late rice growing season but not remarkable in the early rice,while synthetically consideration of their economic earnings and environmental effects, the application of controlled release urea benefitted the most to the rice production, followed by nitrification inhibitor and biopreparate under the current field management conditions.
