Special fertilize for wheat

The present invention relates to a special fertilizer for wheat, wherein the special fertilizer comprises (by weight) the following components, and is characterized in that a weight ratio of N to P2O5 to K2O to zinc in the fertilizer is 22-25:18-20:4-6.5:0.1-0.3. According to the present invention, the requirements of wheat growth on the macroelements such as nitrogen, phosphorus pentoxide and potassium oxide, and other nutrients are completely met, and with the considering of the requirement of wheat growth on the trace element zinc, the metal ion chelation effect of polyaspartic acid is used to enrich nitrogen, phosphorus, potassium and trace elements so as to be supplied for plants, such that the plants efficiently use the fertilizer, the wheat yield is improved, and the environmental pollution is reduced.
