The invention relates to a fertilizer special for corn. The fertilizer is prepared from, by weight, 60-80 parts of base fertilizer and 2-4 parts of trace fertilizer, wherein the base fertilizer is obtained by mixing urea, ammonium phosphate and potassium chloride in the proportion of 14:3:3, and the trace fertilizer is obtained by mixing borax, ammonium sulfate, magnesium sulfate and potassium fulvate in the proportion of 1.5:1:1:0.5 and adding (4.8-7.2)*10<7> /milliliter of biological bacteria. Compared with the prior art, the fertilizer has the advantages that according to the requirements for nitrogen, phosphorous and potassium in the growth process of the corn, the content ratio of the nitrogen to the phosphorous to the potassium is optimized, the formula is rational, and the nutrition is rich, so that the fertilizer is applicable to corn growth; the combination is reasonable and the nutrition is rich, so that the fertilizer is applicable to the whole corn growth period for growth; meanwhile, the biological bacteria have a good effect on antivirus of the corn, and the potassium fulvate has a good effect on drought resistance of the corn and soil property improvement.
