| 摘 要： | 生物质炭基肥是以生物质炭为基质，与有机、无机肥料配制而成的新型生态环保缓释肥料，也作为土壤改良剂应用于农业生产中，近年来受到农业与环保领域的广泛关注和研究应用。本文讨论了生物质炭基肥缓释性能机制及影响因素，生物质炭基肥的缓释性能在很大程度上取决于磷、氮、钾元素与生物质炭的结合方式。主要结合方式包括静电吸附、络合、矿化等。生物质炭基肥的缓释性能受到生物质炭原料种类、炭基肥制备方法和炭肥配合比的影响。生物质炭基肥通过改善土壤理化性质、调节土壤微生物活性，提高植物对养分的利用效率以及减少土壤中养分流失。综合已有研究与应用结果，需要进一步开展生物质炭基肥在土壤中的长期应用效果、老化过程研究，注重在老化过程中对土壤微生物结构的风险评估；建立生物质炭基肥的标准化应用体系，研究和完善生物质炭基肥对土壤持续的、累加性的改良标准。

| Abstract: | Biochar-based fertilizers refer to biochar-containing organic, inorganic fertilizer, or both. Biochar-based fertilizers have prospects in agricultural production and environmental protection fields because of their nutrient slow-release and environmental-friendly properties. The slow-release property of biochar-based fertilizers is attributed to its combination modes with N, P, and K nutrients, including electrostatic attraction, complexity, mineralization and so on. The raw materials, production process, and ratio of biochar to fertilizer strongly influence the slow-release property of biochar-based fertilizers. Biochar-based fertilizers could improve soil physical and chemical properties, regulate soil microbial activities, improve efficiency of plant nutrients utilization, and reduce loss of nutrients in soil. The researches needed to promote the efficient use of biochar-based fertilizers include: assessment of the long-term effect and aging of biochar after its incorporation into soil; risk assessment of biochar to microbial structure and diversity; monitoring the sustainability and cumulative effect of biochar-based fertilizer in soil remediation; and setting standards for the application of biochar-based fertilizer. |
