The invention provides special fertilizer for single-seed precision sowing of peanuts. The special fertilizer is prepared from following raw materials: 150 parts of biochar, 300 parts of resin-coated urea, 50 parts of urea, 360 parts of calcium superphosphate, 80 parts of potassium sulphate, 300 parts of livestock manure, 7 parts of zinc sulfate, 10 parts of ammonium molybdate, 8 parts of magnesium sulfate, 12 parts of borax, 80 parts of humic acid and 3.2 parts of an additive NAM. The special fertilizer can improve soil, increase the content of carbon-based organic matters in the soil, rapidly transform the soil structure, balance salt and water and create a soil environment beneficial to healthy growth of plants through rapid ripening, so that the soil fertility is improved, the requirements for growth and development of single-seed precision sown peanuts in each growth period are met, early and rapid germination in an early stage is promoted, fertilizer shortage in a late stage is avoided, the growth periods are prolonged, late-stage substance accumulation and transfer to pods are promoted, the pods are full, and the yield and the quality are improved remarkably.
