从国际会议看生物炭研究及产业发展动态——第一届生物炭研究与应用国际研讨会述评

Biochar Research and Industry Development Trends Seen from International Conferences——Review of the First International Symposium on Biochar Research and Application

我国农业发展已处于历史转折和变革期,绿色低碳发展成为新时期农业发展方向。在此背景下,加强耕地保护和质量提升,推进农业废弃物资源化利用,加快化肥农药减施增效、农业面源和重金属污染综合防治与修复等成为农业发展的重大议题。生物炭是生物质材料在厌氧高温条件下热裂解产生的高度芳香化的富碳物质,其独特物理和化学性质使其在土壤、环境和生态等领域具有广泛应用价值,成为土壤和农业可持续管理的重要途径。通过对第一届生物炭研究与应用国际研讨会进行总结与评述,对会议涉及到的生物炭制备及材料、生物炭与农业、生物炭与生态环境、生物炭与碳氮循环、生物炭与黑土地保护等领域的最新进展做了简要概括,对今后生物炭领域的研究热点进行了展望,以期为生物炭研究及产业发展提供参考。

China′s agricultural development has been in the historical transition and transformation period,green and low-carbon development has become the direction of agricultural development in the new period.In this context,strengthening the protection and quality improvement of cultivated land,promoting the resource utilization of agricultural wastes,accelerating the reduction of fertilizer and pesticide application and the high efficiency,and conducting the comprehensive prevention and restoration of agricultural non-point source and heavy metal pollution have become major issues in agricultural development.Biochar was a highly aromatic carbon-rich substance produced by thermal cracking of biomass materials under anaerobic high temperature conditions.Its unique physical and chemical properties made it widely used in soil,environment and ecology,and has become an important approach for the sustainable management of soil and agriculture.By summarizing and reviewing the first international symposium on biochar research and application,the latest advances in biochar preparation and materials,biochar and agriculture,biochar and ecological environment,biochar and carbon and nitrogen cycle,biochar and blackland conservation were briefly summarized,and the research hotspot in the field of biochar was prospected,so as to provide reference for biochar research and industry development.
