The invention discloses a weeding composite material for avoiding soil consolidation. The material is prepared from a modified slow release filler, a soil amendment, silica gel, talcum powder, acetyl chitosan, fucoidan, sodium polyphosphate, hexamine, sulfamic acid, sodium percarbonate, amide percarbonate, sodium chloride, copper sulfate, ferrous sulfate, dichlorphenoxyacetic acid, penoxsulam, pyribenzoxim, flucetosulfuron, quinclorac, cyhalofop-butyl, metribuzin, fentrazamide, octyl methoxycinnamate, glycerin, n-butyl acetate, monopotassium phosphate, sodium tetraborate and dodecylbenzene sodium sulfate. The weeding composite material can carry out efficient high-quality release on a weeding additive to improve the efficiency and quality of weeding and meanwhile avoid soil consolidation and soil depletion in the process of weeding.
