水稻低碳生产研究进展
Progress in Research on Low-carbon Rice Production Technology
摘要
Abstract
China is the most important rice producing country in the world and rice production process is one of the important emission sources of methane and nitrous oxide. The production, consumption, and transport of methane and nitrous oxide in rice field are influenced by many factors, such as soil type, water regime, fertilizer, fertilizer application rate, cultivation system and rice variety. There is a trade-off relationship between methane and nitrous oxide emissions in rice field due to water regime change. Although methane emission would be decreased under midseason drainage and moist intermittent irrigation conditions, the emission of nitrous oxide would be enhanced. Therefore, simultaneous minimization of methane and nitrous oxide emission from rice field is a very important technology for low carbon rice production. In addition, soil carbon sequestration in rice field is another key technology for changing rice field from greenhouse gas emission source to sink. This review summarized the progress in research on emission of methane and nitrous oxide from rice field, change of soil organic carbon, mitigation of greenhouse gas emission. The effect of key factors on methane and nitrous oxide emissions from rice field, major methods of increasing soil organic matter and evaluation of mitigation options using global warming potential were emphasized and the further studies of low carbon rice production were discussed.关键词
