The invention relates to the field of fertilizers, in particular to a preparation method of a selenium enrichment base fertilizer for crops. By weight, 200-300 parts of farmyard manure, 10-20 parts of oil cakes, 10-20 parts of attapulgite mineral powder, 20-50 parts of onion, 8-12 parts of yeast, 10-15 parts of vitamins, 3-5 parts of coenzyme II, 5-8 parts of fulvic acid, 8-15 parts of ferrous sulfate, 10-20 parts of amino acid, 15-25 parts of sodium selenate, 30-50 parts of plant ash and 10-20 parts of pond sludge are selected to be subject to fermentation and mixing to prepare a product. The preparation method is simple and easy to operate. Various elements which are contained in the product and are needed by the crops are abundant; in addition, the soil environment can be effectively improved, and growth of plants is simulated; and meanwhile, absorption of the selenium element by the crops is guaranteed. 本发明涉及肥料领域，尤其是种农作物富硒基肥的制备方法的制备方法，按重量份计选取农家肥200～300份、油枯10～20份、凹凸棒土矿粉10～20份、洋葱20～50份、酵母8～12份、维生素10～15份、辅酶I
