| description | Rice is the staple food of nearly half the global population, and its production must steadily increase to meet the growing demand driven by an increasing global population. While an increase in rice production heavily relies on substantial water and fertilizer inputs, which not only decreases water and fertilizer use efficiencies, but also pose significant environmental risks. Therefore, it is an urgent need to enhance yield and resource use efficiency through the development and adoption of innovative, sustainable and environmentally-friendly technologies. This paper reviews progress in green rice production over recent decades based mainly on such research. Firstly, it explores physiological strategies aimed at enhancing yield and improving resource use efficiency in rice production. Secondly, it proposes three key agronomic and physiological strategies to achieve green rice production: optimizing the grain-leaf ratio to balance source-sink dynamics, enhancing the sugar-spikelet ratio to improve sink strength and facilitate non-structural carbohydrates remobilization during grain filling, and increasing ratio of productive tillers to optimize canopy structure. Based on these strategies, a quantitative evaluation of rice population characteristics was undertaken to achieve high yield and resource use efficiency. Thirdly, green technologies for rice production is introduced, including alternate wetting-drying irrigation, three-criteria nitrogen application (based on soil, leaf color and cultivar), and water-nitrogen coupling regulation. Finally, the implication of these technologies is summarized for the major rice-growing areas in China, including Anhui, Heilongjiang, Hubei, Jiangsu, Jilin and Sichuan, and Shanghai. The future prospects for sustainable rice production is then discussed, emphasizing the potential of green technologies to meet the growing demand for rice in an environmentally sustainable way. |
