[0002] Under the new normal of circular economy, the comprehensive utilization of straw has become a new model for dealing with this kind of field waste. Based on the promotion of mechanized recycling, straw has gradually been used in many ways, such as returning to the field, making it into feed, and turning it into biogas. As time goes by, various regions will explore more channels for the comprehensive utilization of straw.

[0003] Straw carbonization is currently a popular way to recycle straw. Straw charcoal can be used as energy, which is a renewable energy and clean energy; straw charcoal can also be used as a raw material for carbon-based fertilizer. The straw charcoal fertilizer returns to the field to improve soil is to convert crop straw into biochar rich in stable organic matter through a medium-low temperature thermal cracking process, and then use biochar as a medium to produce carbon-based fertilizers, which are returned to farmland to improve soil structure and other physical and chemical properties and increase soil organic carbon content.
