The invention discloses trichoderma biological humic acid and a product thereof. The trichoderma biological humic acid comprises trichoderma mycelia, trichoderma spores, trichoderma metabolite, biological humic acid, biochemical fulvic acid, amino acid, nucleic acid, gibberellic acid, indolic acid, cellulose and xylogen. The trichoderma biological humic acid is prepared by the following methods: uniformly mixing one or more raw materials of straws, pot ale, wooden meal, pomace and livestock manure and crushing; then carrying out degradation by virtue of alkali or ammonia, so as to obtain a degraded product; adding a 0.02wt%-0.1wt% of a trichoderma agent and 50wt%-60wt% of water on the basis of weight of the degraded product, uniformly mixing, carrying out aerobiotic or aerobic fermentation at 20-35 DEG C for 5-7 days so as to prepare trichoderma biological humic acid, wherein the trichoderma agent is trichoderma harzianum or trichoderma viride. The trichoderma biological humic acid can replace chemical fertilizers, so that the consumption of pesticides can be reduced, water, the fertilizerand the pesticides can be integrated, the total amount of water, the fertilizer and the pesticides is saved by 20%-50%, soil can be effectively improved, soil organic matter is improved, the micro-ecological environment of soil is repaired, and the disease resistance and the adverse resistance of crops are improved, soil-borne diseases are inhibited, the successive cropping obstacle is prevented and controlled, the consumption of the chemical fertilizer and the pesticide can be reduced, and all the effects are obvious.
