国际生物炭专家赴洛宁烟草学院基地调研炭基肥全链条应用--International Biochar Experts Visit Luoning for Application of Biochar

秋雨沥沥，万物丰泽。8月11日至12日，第三届生物炭研究与应用国际研讨会暨2026国际生物炭世界大会落幕之后，海内外权威专家学者组团赴河南省洛宁县，开展生物炭基肥产业实践与田间应用专项考察调研。国际生物炭协会（IBI）董事会主席Lucia Brusegan，英国爱丁堡大学生物炭研究中心主任Ondrej Masek教授等40多位中外知名专家参与本次考察。洛宁县政府副县长仝朝阳，沈阳农业大学国家生物炭研究院院长孟军教授、副院长李无双教授，河南农大烟草学院副院长任天宝，洛宁县科技局、烟草公司、小界镇、长水镇、马店镇等乡镇负责人，河南惠农土质保育研发有限公司董事长袁占军等陪同调研考察。

Autumn rain drizzles, nourishing all things.From August 11 to 12, following the conclusion of the 3rd International Symposium on Biochar Research and Application & 2026 International Biochar World Congress, a delegation of leading domestic and international experts undertook a dedicated field inspection and research visit to Luoning County, Henan Province, focusing on the industrial application and field-based practices of biochar-based fertilizers. More than 40 renowned Chinese and foreign specialists participated in the visit, including Dr. Lucia Brusegan, Chair of the Board of Directors of the International Biochar Initiative (IBI), and Professor Ondrej Masek, Director of the Biochar Research Centre at the University of Edinburgh, UK. Accompanying the delegation during the inspection were Mr. Tong Zhaoyang, Deputy County Governor of Luoning County; Professor Meng Jun, Dean of the National Biochar Institute of Shenyang Agricultural University; Professor Li Wushuang, Deputy Dean of the same institute; Professor Ren Tianbao, Deputy Dean of the College of Tobacco Science at Henan Agricultural University; representatives from the Luoning County Bureau of Science and Technology and the township governments of Xiaojie, Changshui, and Madian; and Mr. Yuan Zhanjun, Chairman of Henan Huinong Soil Conservation Research and Development Co., Ltd.

考察组首站来到洛宁县王村烟田示范基地，现场对比常规种植地块与生物炭基肥示范田的烟株长势。任天宝围绕烟区连作障碍、土壤碳氮失衡及质量下降等生产痛点，详细讲解生物炭基肥改良植烟土壤、适配田间施用方法、提升烟叶产质量的实际成效。在示范区烟田，每公顷施用 900至1200千克生物炭基肥，可实现化肥氮素减量20%至30%，烟株根际微生物群落结构得到显著优化，根区土壤碳氮比提升 13.5%至16.8%，烟叶产质量显著提升。专家组就地交流大面积推广过程中的技术适配方案。

The inspection team's first stop was the Wangcun Tobacco Field Demonstration Base in Luoning County, where they conducted an on-site comparison of tobacco plant growth between conventional cultivation plots and biochar-based fertilizer demonstration fields. Professor Ren Tianbao provided a detailed explanation of the practical effectiveness of biochar-based fertilizers in improving tobacco-planting soils, optimizing field application methods, and enhancing tobacco leaf yield and quality, with a particular focus on addressing key production challenges such as continuous cropping obstacles, soil carbon‑nitrogen imbalance, and soil degradation in tobacco-growing areas. In the demonstration plots, the application of 900 to 1,200 kilograms of biochar-based fertilizer per hectare achieved a 20% to 30% reduction in synthetic nitrogen fertilizer use, significantly optimized the rhizosphere microbial community structure of tobacco plants, and increased the root-zone soil carbon‑nitrogen ratio by 13.5% to 16.8%. The expert group held on-site discussions on technical adaptation strategies for large-scale promotion of this approach.

随后，考察组深入生产一线，来到河南农业大学烟草学院生物炭工程技术研究中心科技成果转化基地——河南惠农土质保育研发有限公司。在生产基地，孟军详细讲解了连续式生物质炭化设备的工作原理与技术优势；袁占军则现场演示了生物炭基肥自动化生产线的结构布局与运行特点。考察组专家边看边问，详细了解了生物炭及炭基肥的核心技术参数，并围绕生物质炭化工艺优化、炭基肥规模化生产以及产品质量管控等关键议题展开了深入交流。

Subsequently, the inspection team proceeded to the front line of production and visited the Henan Huinong Soil Conservation Research and Development Co., Ltd., which serves as the industrialization base for scientific and technological achievements of the Henan Provincial Biochar Engineering Technology Research Center. At the production facility, Professor Meng Jun provided a detailed explanation of the working principles and technical advantages of the continuous biomass carbonization equipment. Mr. Yuan Zhanjun then gave a live demonstration of the structural layout and operational characteristics of the automated biochar-based fertilizer production line. The visiting experts engaged in thorough discussions, raising questions throughout the process and gaining in-depth insights into the core technical parameters of biochar and biochar-based fertilizers. They also conducted extensive exchanges on key topics including the optimization of biomass carbonization processes, large-scale production of biochar-based fertilizers, and product quality control.

除了传统经济作物，生物炭技术的应用边界还在不断拓宽。考察组还调研了生物炭基肥在黄芩、甘草等中药材及金珠沙梨等经济作物上的应用示范。现场调研结果表明，生物炭基肥在改良土壤理化性状、优化根际微生物群落、促进矿质营养吸收以及提升农产品内在品质等方面成效显著。这不仅为特色种植产业的提质增效拓展了广阔空间，也进一步丰富了生物炭技术多维度的落地应用场景。

Beyond traditional cash crops, the application boundaries of biochar technology continue to expand. The inspection team also investigated the demonstrative applications of biochar-based fertilizers on traditional Chinese medicinal herbs such as Scutellaria baicalensis (huangqin) and Glycyrrhiza uralensis (licorice), as well as on cash crops like the golden pear (Jinsha pear). On-site findings demonstrated that biochar-based fertilizers have achieved remarkable results in improving soil physicochemical properties, optimizing rhizosphere microbial communities, promoting mineral nutrient uptake, and enhancing the intrinsic quality of agricultural products. These outcomes not only open up broad prospects for improving the quality and efficiency of specialty crop cultivation but also further enrich the multidimensional application scenarios of biochar technology in practical settings.

考察间隙，专家围绕炭基产品迭代研发、田间长期定位效果监测、产业化推广机制等核心议题深度交流，有利于打通国内外科研院所与本土生产企业的常态化合作渠道。

During intervals of the field inspection, the expert delegation held intensive discussions centered on key strategic priorities, including the iterative upgrading of biochar-based products, long-term in-situ monitoring of field efficacy, and scalable mechanisms for industrial dissemination. These deliberations are expected to facilitate the establishment of sustained, routine collaborative channels between domestic and overseas research institutions and local manufacturing partners.

此次实地调研被参会专家称作“行走的学术会议”，打破了传统会议室内听报告的单一交流模式，完整展现生物炭技术从实验室研发、中试试验、工业化生产到大田规模化应用的全链条闭环。活动以农林废弃物炭化利用与生物炭产业应用为抓手，持续深化产学研用协同创新，推动生物炭科技成果走出实验室、落地田间，形成一套可复制、可推广的绿色农业中国方案，为全球耕地保育与低碳农业发展提供实践参考。

The field inspection, hailed by experts as a "walking academic conference," broke the confines of traditional indoor presentations and showcased the full closed‑loop chain of biochar technology—from lab R&D and pilot testing to industrial production and large‑scale field deployment. By promoting the carbonization of agricultural and forestry residues and the industrial application of biochar, the event further strengthened collaborative innovation across industry, academia, and research. It translated biochar innovations from the lab to the field, establishing a replicable and scalable Chinese model for green agriculture, while providing practical insights for global soil conservation and low‑carbon farming.

专家组表示：“将生物炭技术如此高效地应用到农业生产，洛宁的生物炭应用实践为全球土壤改良和低碳农业提供了很好的样本。”该创新交流模式也标志着国际农业科技合作迈入全新阶段，合作重心从单一论文学术交流，转向实地联合研究、产业协同共建，为我省乃至全国农业绿色低碳转型集聚优质国际科研资源。

The expert group remarked that "the application of biochar technology to agricultural production with such high efficiency—as demonstrated in Luoning's practical implementation—provides an exemplary model for global soil improvement and low-carbon agriculture."This innovative model of academic exchange also marks a new phase in international agricultural science and technology cooperation, with the focus shifting from solitary paper-based academic communication to joint field research and collaborative industrial development. This transition will help pool high-quality international research resources for the green and low-carbon transformation of agriculture in Henan Province and across China.
