摘　　要：分析了华南双季稻田CH4和N2O排放量,从低碳品种筛选、节水减排灌溉、化肥减量增效等方面介绍了华南双季稻低碳高产关键技术及其集成应用情况。综述了华南双季稻低碳高产栽培技术研究的主要进展、存在问题和今后工作重点。华南双季稻低碳高产栽培技术节水节肥、减排控污、增产增收,实现了低碳与高产的协调,应用前景好。目前,该技术主要存在可用品种少、种植模式单一、推广难度大等问题;今后,在加大政策支持的同时,亟需加强品种筛选、模式集成、基础理论等方面的研究,以确保国家粮食安全,实现碳达峰碳中和的目标。The key technologies for low-carbon and high-yield of double-cropping rice in South China(DCRSC)and their integrated application were introduced from the aspects of low-carbon variety selection,water-saving and emission reduction irrigation,and fertilizer reduction and efficiency enhancement,etc.The main progress,problem and future focus on the development and extension of low-carbon and high-yield technology for DCRSC were summarized.The low-carbon and high-yield cultivation technology for DCRSC could synergize water-saving and fertilizer-saving,emission reduction and pollution control,high yield and income,realized the coordination of low-carbon and high-yield,therefore it would have a good application prospect.There are main problems for this technology including limited available varieties,undiversified planting modes,and difficult promotion at present.While increasing policy support,further efforts are needed to enhance the improvement and extension of the new technology,including variety screening,cropping pattern optimization and basic research,so as to ensure national food security and achieve carbon peak and carbon neutrality goals.
