Example Embodiment
[0026] Example 1
[0027] A microbial slow-release compound fertilizer consisting of the following parts by weight of raw materials: 6 parts of rice husk biomass charcoal, 15 parts of fermented organic fertilizer, 3 parts of potassium fulvic acid, 4 parts of monoammonium phosphate, 18 parts of urea, and lignin 6 parts, 9 parts of montmorillonite, 1 part of bacteria-containing concentrate, 8 parts of polyvinyl alcohol, 14 parts of corn starch, 1 part of oxalic acid, 0.2 part of silicon dioxide.
[0028] Further, the biomass charcoal is prepared by pyrolyzing rice husks at 500° C. under anoxic conditions, and has a particle size of 1.0-2.0 mm.
[0029] Further, the fermented organic fertilizer uses livestock manure as a raw material, corn stalks as a conditioning agent, after adjusting the moisture content, adding biomass charcoal, mixing uniformly, preparing by aeration and oxygen fermentation, drying and pulverizing, with a particle size of 3~ 4mm.
[0030] Further, the bacteria-cont...
