The invention relates to a production method of a multielement efficient humic acid compound fertilizer. The production method mainly comprises the following parts: (1) smashing and screening coal; (2) spraying lye and activating humic acid in the coal; (3) naturally piling, after action for a certain time, drying and smashing to obtain a humic acid finished product; (4) after pre-mixing a magnesium-containing material, a zinc-containing material, a boron-containing material, a growth regulator, a filler and an optional dispersing agent by a pre-mixing groove, sending to a mixer for mechanically mixing with the humic acid; (5) adding the materials mixed in part (4) into mixture slurry, prepared by mixing and fusing, of two or three of a nitrogen fertilizer, a phosphatic fertilizer and a potash fertilizer, prilling by a high tower, a rotary drum or a squeezing prilling process, screening, and then performing surface treatment to obtain a particle compound fertilizer finished product. The compound fertilizer has the characteristics of complete nutrition, high efficiency and good solubleness, and has good application prospects.
