| 摘要: |
| 本文提出了一种水热炭复合肥(Hydrothermal Carbon Compound Fertilizer，HCCF)技术路线，以农作物秸秆等农林废弃物为原料，采用水热法把生物质转化为富含腐殖酸的水热炭(褐煤)，将其作为底物与氮、磷、钾等肥料成分复合，生产长效、缓释的水热炭复合肥。将该肥料施用于农田，可提高土壤肥力，改善土壤的团粒结构。水热炭复合肥是一种有商业价值的负碳产品，可以大规模生产，以提升土壤碳汇，储碳于田，促进碳中和目标达成，同时具有高产、环保和生态等多方面的效益，推进生态、有机和可持续农业的发展。 |

| Abstract: |
| In this article Hydrothermal Carbon Compound Fertilizer (HCCF) technology route was proposed,a hydrothermal carbon (lignite) rich in humic acid was prepared by hydrothermal method using agricultural and forestry waste such as crop straw as raw materials. It was used as a substrate to compound with nitrogen,phosphorus,potassium and other fertilizer components to produce long-term and slow-release HCCF,which was applied to farmland to improve soil fertility and improve soil aggregate structure. Hydrothermal carbon compound fertilizer is a kind of negative carbon product with commercial value. It can be produced on a large scale,improve soil carbon sink,store carbon in the field,and promote the achievement of carbon neutralization goals.At the same time,it has many benefits such as high yield,environmental protection and ecological benefits,and promotes the development of ecological,organic and sustainable agriculture. |
