水稻根际环境与氮素利用的关系研究进展

Research Progress on Relationship Between Rice Rhizosphere Environment and Nitrogen U-tilization

氮素高效利用是实现水稻高产和建立环境友好型农业的关键一步。根际环境与氮素能否高效利用密切相关,也是近年来栽培、土壤及生态学领域的研究热点。本文总结了水稻根际环境的定义及范畴,解析了水稻氮素吸收利用的相关机制,阐述了根际土壤、根系以及根际微生物与氮素利用的关系,分析了目前存在的问题和对未来研究的展望。

High-efficiency utilization of nitrogen is the key to achieving high rice yield and establishing environmentally friendly agriculture.The rhizosphere environment is closely related to whether nitrogen can be efficiently used,and it is also a research hotspot in the fields of cultivation,soil and ecology in recent years.We summarize the definition and category of rice rhizosphere environment,analyze the relevant mechanisms of nitrogen absorption and utilization by rice,expound the relationship between rhizosphere soil,root system,and rhizosphere microorganisms and nitrogen utilization,and analyze current problems and prospects for future research.
