Embodiment 1
[0016] This embodiment relates to crop residue utilization and fertilizer production technology, and particularly provides a method for producing compound fertilizer by using straw.
[0017] This embodiment specifically provides a method for producing compound fertilizer from straw. Cut the straw into sections, put the straw sections into a fermentation tank, add an organic decomposing agent, cover with an environmentally friendly and degradable plastic film or seal it with mud; After impurity removal and purification, the biogas is transported to residents' homes for burning or / and for production use or / and storage; after the remaining biogas residue and biogas slurry are separated, the biogas residue is crushed and used as pollution-free organic full-nutrient solid fertilizer or For storage, the biogas slurry is used or stored as a pollution-free organic full-nutrient liquid fertilizer; when using fertilizers, solid fertilizers and liquid fertilizers are used alone or in comb...
