Universal slow release fertilizer for sugarcane

The invention relates to a universal slow release fertilizer for sugarcane, and scientifically proposes a slow release fertilizer formula, namely N:P2O5:K2O equals to 15:10:5, suitable for wide sugarcane producing areas in China according to a nitrogen, phosphorus and potassium application principle, the nutrient status of soil of the main sugarcane producing areas in China and a fertilizer requirement law of sugarcane. In the formula, the total nutrient content is 30%. The slow release fertilizer is prepared by mixing the following raw materials according to mass ratio: 310-326 kg of urea containing 46% of N, 0-82 kg of monoammonium phosphate containing 49% of P2O5 and 9% of N, 333-556 kg of calcium magnesium phosphate containing 18% of P2O5, 83kg of potassium chloride containing 60% of K2O, 8kg of a fertilizer inhibitor, 2kg of a fertilizer synergist and 25-182kg of fillers.
