The invention relates to dedicated wheat
fertilizer with the characteristic of disposable fertilization, the problems of
fertilizer for wheat planting that second
pollution cannot be prevented, and the cost is expensive can be effectively solved. The dedicated wheat
fertilizer is characterized by being prepared from the following raw materials in percentage by weight: 13 to 25 percent of
urea, 16to 39 percent of
ammonium chloride, 18 to 22 percent of monoammonium
phosphate, 8 to 10 percent of
potassium chloride and 18 to 30 percent of clay mineral granule
controlled release agent. The dedicated wheat fertilizer is prepared through the following steps: mixing the
urea,
ammonium chloride and the clay mineral
controlled release agent together, thus preparing a material A; mixing
potassium chloride with the material A, thus preparing a material B; uniformly mixing monoammonium
phosphate with the material B, thus preparing granules;
drying and sieving the granules, and enabling the granules of which the
granularity is 3.35 to 5.6 mm to be up to 90 percent or above, thus obtaining a finished product. The dedicated wheat fertilizer disclosed by the invention has the characteristic of realizing one-season fertilizer supplying through
single fertilization, not only can good
nutrient elements be provided for wheat, but also the demands on
nitrogen fertilizer during a whole growth periodof the wheat can be met, raw materials are rich, the preparation method is simple, the cost is low, a using effect is good, the dedicated wheat fertilizer can be effectively used for planting the wheat, and high yield and good harvest are ensured.
