The invention provides a nano carbon organic compound fertilizer. The nano carbon organic compound fertilizer is composed of following components according to suitable weight parts: urea, monopotassium phosphate, hairs, palygorskite, dimethyl sulfoxide, a boron fertilizer and zinc fertilizer mixture with the weight ratio of 1:0.5, ferrous sulfate, nodule bacteria, azotobacter chroococcum, nano carbon, rhizoma curculiginis, pseudolarix kamepferi, radix sophorae flavescentis, ligninase, plant ash, humic acid, dicyandiamide, animal dung and powdery EDTA (Ethylene Diamine Tetraacetic Acid) chelated manganese. The nano carbon organic compound fertilizer can be good for effective utilization of secondary elements and microelements, is suitable for crops including wheat, rice, corns, soybeans, oilseed rapes and the like, and can enhance the cold-resisting, drought-resisting, and disease and insect pest-resisting functions; the nano carbon organic compound fertilizer can be used on cotton and linen crops to enhance the tension and the strength of fibers and the yield and the quality are obviously improved.
