The invention provides special slow-release fertilizer used for wheat and applicable to yellow brown soil and an application. The formula fertilizer comprises effective elements based on pure nutrients in percentage by weight as follows: 24%-26% of nitrogen, 10%-12% of phosphorus pentoxide, 8%-10% of potassium oxide, 0.05% of pure boron, 2%-3% of pure zinc and 0.04%-0.06% of pure molybdenum. The fertilizer requirement characteristics of wheat are considered, the abundance and deficiency characteristics of microelements in the yellow brown soil in main producing areas of wheat are also considered, boron, zinc, molybdenum and other elements easily lacked in the yellow brown soil are properly supplemented, the targeting property is high, the misuse and poisoning phenomena of the microelementsare prevented, besides, the formula adopts slow-release urea, one-time fertilization in the whole growth period of the wheat is realized, time and labor are saved, and yield increase and income increase of farmers are facili
