Embodiment 1
[0038] Humic acid functional blended fertilizer (special for corn, N:P:K=28:6:8)
[0039] (1) The composition of the basic fertilizer: large granular urea (N≧46%, the particle size range of large granular urea is 2-4.75 mm), granular monoammonium phosphate (N≧11%, P 2 o 5 ≧44%), powdered potassium chloride (K 2 O≧55%).
[0040] (2) Composition of auxiliary basic raw materials: powdery humic acid and attapulgite powder (magnesium aluminum silicate mineral powder).
[0041] (3) Preparation of coating material and granulation material:
[0043] ①The composition of granular nitrogen fertilizer coating liquid is expressed in mass percentage as follows: animal amino acid 1.5%, urea 18%, zinc sulfate 2.5%, manganese sulfate 2.0%, boric acid 0.5%, sodium molybdate 0.1%, sodium nitrophenolate 0.1% , citric acid 0.1%, ammonium citrate 0.5%, magnesium sulfate 0.2%, water is the balance.

Embodiment 2
[0070] Humic acid type functional blended fertilizer, the preparation method is the same as embodiment 1, the difference is:
[0071] N:P:K=24:15:6
[0072] Carry out blending proportioning according to above-mentioned prescription. Weigh 440 kg / ton of coated urea, 341 kg / ton of coated monoammonium phosphate, and 219 kg / ton of potassium chloride particles with a potassium chloride content of 28%, mix them evenly with a blender, and measure and pack.
Embodiment 3
[0074] Humic acid type functional blended fertilizer, the preparation method is the same as embodiment 1, the difference is:
[0077] The composition of granular nitrogen fertilizer coating solution is expressed in mass percentage as follows: animal amino acid 3%, urea 20%, zinc sulfate 0.3%, manganese sulfate 2.5%, boric acid 0.1%, sodium molybdate 0.2%, sodium nitrophenolate 0.3%, lemon Acid 0.5%, ammonium citrate 0.8%, magnesium sulfate 0.1, water is the balance.
[0078] The composition of granular nitrogen fertilizer coating powder is expressed as follows in terms of parts by mass: 0.2 parts of vitamin B1, 0.3 parts of vitamin B6, 0.3 parts of vitamin B12, 0.2 parts of sodium selenite, 1 part of calcium pantothenate, 0.2 parts of p-aminotoluic acid, modified 2 parts of starch, 0.3 parts of cobalt chloride.

technical field [0001] The invention relates to the technical field of blended fertilizers. Background technique [0002] The blended fertilizers currently on the market are mostly ordinary types, which are made of large-grain urea, granular phosphate fertilizer, and granular potassium fertilizer in a certain proportion. In the process of processing, some trace elements will not be added, and its effect is only ordinary. Type, basically non-functional. If trace elements are added, they are basically extruded particles of trace elements, which have certain functionality, but the use effect is not high, and the waste is serious. [0003] Functional fertilizers, also known as multifunctional fertilizers, are one of the important research and development directions of new fertilizers in the 21st century. They are fertilizers that combine cropnutrition with other factors that limit crop yields. increase production efficiency. The research and production of multifunctional fer...
