The invention relates to the technical field of fertilizer, in particular to fertilizer with a function of reducing heavy metal pollution of strawberry. The fertilizer is prepared from components in parts by weight as follows: 40-50 parts of urea, 25-30 parts of urea phosphate, 15-20 parts of ground phosphate rock, 20-30 parts of potassium dihydrogen phosphate, 25-30 parts of potassium sulfate, 18-22 parts of potassium nitrate, 15-20 parts of sodium carbonate, 20-25 parts of ammonium bicarbonate, 13-16 parts of amino acid chelate, 15-20 parts of forsterite, 8-12 parts of gypsum, 9-13 parts of citric acid, 15-20 parts of peanut bran, 8-12 parts of fulvic acid, 6-9 parts of diatomite, 5-10 parts of sodium N-dodecyl ethylenediamine triacetate, 15-20 parts of a heavy metal enrichment reagent, 10-15 parts of a microelement extracting solution and 20-30 parts of modified sodium sulfide. The fertilizer is rich in nutrients and contains multiple major elements and micronutrient elements essential for the strawberry, total nutrients of nitrogen, phosphorus and potassium are higher than or equal to 73.2%, and in terms of the strawberry, the yield can be increased by 9.3%-10%; compared with traditional fertilizer, the fertilizer has the advantages as follows: after application of the fertilizer, content of heavy metal copper in mature strawberry fruit is reduced by 66.7%-71.1%, the content of zinc is reduced by 52.8%-58.3%, and the content of nickel is reduced by 64.7%-67.6%.
