The invention provides a blended fertilizer. The blended fertilizer is composed of urea, ammonium dihydrogen phosphate, ammonium sulfate, potassium sulfate, potassium nitrate, boric acid, zinc sodium tetraacetate and a flavoring bag, wherein the flavoring bag comprises a chelating agent, a complex enzyme, fulvic acid and seaweed extract. Every 1500 kg of the finished blended fertilizer is composed of 162.5 kg of urea, 296 kg of ammonium dihydrogen phosphate, 100 kg of ammonium sulfate, 60 kg of potassium sulfate, 366 kg of potassium nitrate, 9 kg of boric acid, 3.5 kg of zinc sodium tetraacetate, 50 kg of the chelating agent, 100 kg of the complex enzyme, 273 kg of fulvic acid and 80 kg of seaweed extract. The blended fertilizer provided by invention adopts three major ecological chain technologies and utilizes organic carbon for chelation with residual salt in soil, so the root systems of crops are well developed, the quality and appearance of fruit are improved, the purposes of increasing yield and increasing the income of farmers are achieved, and the problems of soil acidification, soil hardening, soil-borne diseases and the like are overcome. Thus, the blended fertilizer has good promotion value.
