Disclosed are a specialized fertilizer for a paddy and a preparation thereof, and a method for producing rice. The specialized fertilizer for the paddy consists of the following components in parts by weight: 1-1000 parts of a nutrient, 500-1000 parts of dried fine soil and 50-200 parts of biomass filler materials, wherein the nutrient is a substance containing one of the following or a combination thereof: nitrogen, phosphorus, potassium, calcium, iron, zinc, selenium, iodine, boron, molybdenum, copper, cobalt, manganese, chromium, nickel, fluorine, vanadium, silicon or strontium. The specialized fertilizer for the paddy provided in the present application has readily available raw materials and a simple preparation process. When used to produce rice, during the transplanting of the paddy with a machine, the specialized fertilizer for the paddy transplanted with a machine can be synchronously applied to the roots of the seedlings to efficiently supply nutrients to the paddy for a long time. The method provided by the present application requires less labour, cleverly uses a rice transplanter to apply the fertilizer to save labor, and the application point of the fertilizer is precisely located at the rhizosphere of the paddy, thus having a higher utilization factor than broadcasting the fertilizer.L'invention concerne un engrais spécialisé pour une rizière et sa préparation, et un procédé de production de riz.
