Embodiment 1
[0027] Embodiment 1: a special fertilizer for wheat, with urea, monoammonium phosphate, potassium chloride and weathered coal as basic raw materials, granulation additives are fertilizer adhesives and activation additives, the mass parts of each component are: 29 parts of urea , 20 parts of monoammonium phosphate, 16 parts of potassium chloride, 30 parts of weathered coal, 4 parts of fertilizer adhesive and 1 part of activation additive; described fertilizer adhesive is activated clay, and described activation additive is potassium hydroxide .
[0028] The preparation method is as follows:
[0029] Batching and granulation: drying the raw materials of urea, monoammonium phosphate and potassium chloride to a water content of ≤2wt%, and drying the weathered coal raw materials to a water content of ≤20wt%. After the raw materials are dried, they are pulverized so that the particle diameter of each raw material component is 0.1-0.3 mm. The dried and pulverized raw materials are ...
Embodiment 2
[0036] A special fertilizer for wheat, the mass parts of each component are: 19 parts of urea, 20 parts of monoammonium phosphate, 16 parts of potassium chloride, 40 parts of weathered coal, 3.5 parts of fertilizer adhesive and 1.5 parts of activation additive; The fertilizer adhesive is activated clay, and the activation additive is potassium hydroxide.
[0037] The preparation method is the same as in Example 1. The nutrient content of special fertilizer for wheat is N:P 2 o 5 : K 2 O=9:8:9.
[0038] This special fertilizer for wheat is suitable for use as a base fertilizer in land with medium soil fertility, and the application rate is 1500kg / hm 2 , 15kg of urea can be applied at the jointing stage. Compared with farmers' customary fertilization method, the yield is increased by about 10%.
Embodiment 3
[0040] A special fertilizer for wheat, the mass parts of each component are: 11 parts of urea, 22 parts of monoammonium phosphate, 18 parts of potassium chloride, 44 parts of weathered coal, 3 parts of fertilizer adhesive and 2 parts of activation additive; The fertilizer adhesive is activated clay, and the activation additive is potassium hydroxide.
[0041] The preparation method is the same as in Example 1. The nutrient content of special fertilizer for wheat is N:P 2 o 5 : K 2 O=7:9:10.
[0042]This special fertilizer for wheat is suitable for use as a base fertilizer in plots with high basic soil fertility, and the application rate is 1500kg / hm 2 , 15kg of urea can be applied at the jointing stage. Compared with farmers' customary fertilization method, the yield can be increased by about 9%.
