Special fertilizer for open-field muskmelons and application method

The invention provides a special fertilizer for open-field muskmelons. The special fertilizer consists of four groups of fertilizers A, B, C and D, wherein the group A fertilizer is prepared from 72.0to 84.0 kg / hm2 of N, 78.0 to 90.0 kg / hm2 of P2O5 and 36.0 to 60.0 kg / hm2 of K2O; the fertilizer in the group B comprises 48.0-56.0 kg / hm2 of N; the fertilizer in the group C comprises 72.0-84.0 kg / hm2 of N; the fertilizer of the group D comprises 48.0 to 56.0 kg / hm2 of N and 54.0 to 90.0 kg / hm2 of K2O; wherein the application amounts of N, P2O5 and K2O are based on pure nutrient amounts. Methodsof application are also provided. When the special fertilizer is applied, compared with habitual fertilization of farmers, the nitrogen fertilizer consumption is reduced by 15.2% on average, the phosphate fertilizer consumption is reduced by 9.7%, the muskmelon yield is increased by 8.4%, and the pure income is increased by 11.3%.
