Biomass high-efficiency hydrothermal integrated carbonization process and application of product of biomass high-efficiency hydrothermal integrated carbonization process in preparation of carbon-based organic fertilizer mulching film

The invention relates to a biomass high-efficiency hydrothermal integrated carbonization process and application of a product of the biomass high-efficiency hydrothermal integrated carbonization process in preparation of a carbon-based organic fertilizer mulching film. In the process implementation process, no emission is generated, green, environment-friendly, clean, continuous and large-scale mass production is achieved, on the premise of mildness, safety, stability and high efficiency, the three parallel three-screw straw splitting and brooming machines of different models are combined into a Z-shaped three-order primary-secondary machine (I-type, II-type and III-type) production line in a linkage mode, and the production efficiency is improved. Under the synergistic effect of various mechanical forces, an integrated efficient hydrothermal carbonization process of tempering and modifying a hydrothermal response precursor raw material, continuously generating a carbon skeleton, reinforcing a stepped carbon
