Abstract:

Rice is one of the most important cereal crops in China, and paddy field is also the main source of greenhouse gas methane and nitrous oxide emissions. Biochar has been widely used in soil improvement and crop yield improvement due to its strong stability, adsorption and high pH value. At the same time, biochar can affect soil microorganisms in paddy fields, thereby directly or indirectly affecting the emission of greenhouse gases in paddy fields. This paper summarized the effects of biochar on soil physicochemical properties, greenhouse gas emissions and rice yield, and put forward the research direction in the future, so as to provide theoretical and practical basis for efficient rice production and paddy field greenhouse gas emissions reduction.

Key words: rice, biochar, soil physical and chemical properties, growth, yield, greenhouse gas

摘要:

水稻是我国最主要的粮食作物,稻田也是温室气体甲烷和氧化亚氮的主要排放源。生物质炭因其具有较强的稳定性、吸附性和pH值高等特性,在改良土壤、提高作物产量等领域得到广泛应用。同时,生物质炭能够对稻田土壤微生物产生影响,直接或间接影响稻田温室气体的排放。本文总结了生物质炭对稻田土壤理化特性、温室气体排放及水稻产量的影响,提出了未来的研究方向,以期为水稻的高效生产及稻田温室气体减排提供理论与实践依据。
