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.","PeriodicalId":12565,"journal":{"name":"Frontiers of Agricultural Science and Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://journal.hep.com.cn/fase/EN/PDF/10.15302/J-FASE-2025610","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147877812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, systematic research was conducted on HM levels in hydrochar from dairy manure and on the effects of processing conditions, including processing temperature (180–255 °C), holding time (30<i>–</i>120 min) and solid content of manure slurry (2%<i>–</i>15%), through a central composite design and statistical analyses. It was found that HMs can be retained in hydrochar, ranging from 40% to 100%. The processing temperature and solid content in the feed were the most influential process parameters that affected HMs retention in hydrochar. Statistical analysis showed that there was no single optimal point to minimize HMs retained in hydrochar, but there were minimization points at given processing time and solid content. Most HMs concentrations were higher in hydrochar than those initially in dairy manure but were greatly below the thresholds as set by the US government regulations. Thus, hydrochar is feasible for use as a phosphorus-enriched organic fertilizer and/or soil amendment for agricultural applications without serious concerns about HMs it might contain.","PeriodicalId":12565,"journal":{"name":"Frontiers of Agricultural Science and Engineering","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135440781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
