Problems solved by technology

At present, most of the fertilizers used for wheat planting are nitrogen, phosphorus and potassium compound fertilizers. Although they can meet the growth needs of wheat in a short period of time, long-term use will damage the soil aggregate structure, which will easily cause soil compaction, soil hardening, and reduce soil fertility. At the same time, pure inorganic fertilizers have low fertilizer efficiency and cannot evenly distribute the various nutrients needed for wheat growth, thus affecting the growth of wheat

Embodiment 1

[0010] A special controlled-release fertilizer for corn and a preparation method for a compound fertilizer for wheat, specifically: 38 parts by weight of urea, 38 parts of diammonium phosphate, 22 parts of potassium chloride, 35 parts of corncobs, humus 27 parts of acid, 5 parts of modified starch, 3 parts of linseed oil, 5 parts of rosin resin and 6 parts of bentonite, firstly mix corn cob, humic acid, urea, diammonium phosphate and potassium chloride, and mix well to obtain powder , then add water to partially dissolve the powder, then add modified starch, stir and heat to boiling, then add bentonite, continue stirring, and finally add pre-melted rosin resin, heat and evaporate to dryness while stirring, and dry until the fertilizer moisture is in the Below 10%, granulate to obtain compound fertilizer. The preparation method is specifically: take 200 parts by weight of polypeptide urea, 130 parts of sulfur-coated urea, 150 parts of large particle urea, 140 parts of diammoniu...

Embodiment 2

[0012] A preparation method for a compound fertilizer for wheat, specifically: 35 parts by weight of urea, 35 parts of diammonium phosphate, 18 parts of potassium chloride, 30 parts of corncobs, 25 parts of humic acid, 4 parts Modified starch, 2 parts of linseed oil, 4 parts of rosin resin and 5 parts of bentonite, firstly mix corncobs, humic acid, urea, diammonium phosphate and potassium chloride, and mix well to obtain a powder, then add water to make the powder Partially dissolve the material, then add modified starch, stir and heat to boiling, then add bentonite, continue to stir, and finally add pre-melted rosin resin, heat and evaporate to dryness while stirring, dry until the moisture content of the fertilizer is below 10%, and granulate to obtain compound fertilizer.

Embodiment 3

[0014] A preparation method for a compound fertilizer for wheat, specifically: 43 parts by weight of urea, 42 parts of diammonium phosphate, 25 parts of potassium chloride, 40 parts of corncobs, 30 parts of humic acid, 6 parts Modified starch, 4 parts of linseed oil, 6 parts of rosin resin and 7 parts of bentonite, firstly mix corncobs, humic acid, urea, diammonium phosphate and potassium chloride, and mix well to obtain a powder, then add water to make the powder Partially dissolve the material, then add modified starch, stir and heat to boiling, then add bentonite, continue to stir, and finally add pre-melted rosin resin, heat and evaporate to dryness while stirring, dry until the moisture content of the fertilizer is below 10%, and granulate to obtain compound fertilizer.

Abstract

The invention relates to a composite fertilizer for wheat and a preparation method thereof. The composite fertilizer comprises, by weight, 35-43 parts of urea, 35-42 parts of diammonium phosphate, 18-25 parts of potassium chloride, 30-40 parts of corn cob, 25-30 parts of humic acid, 4-6 parts of modified starch, 2- 4 parts of linseed oil, 4-6 parts of rosin resin and 5-7 parts of bentonite. The composite fertilizer provided by the invention has reasonable formula, comprehensive and balanced nutrition, not only contains wheat growth needed nitrogen, phosphorus, potassium, trace elements, but also contains rich organic acids, peptides and other organic matters, and can satisfy the needs of wheat for all nutrients in the whole growth period. Also, the composite fertilizer provided by the invention can slow the fertilizer nutrient release rate, improve nutrient use ratio, reduce the fertilizer loss, ease the environmental pressure caused by fertilization, and has good ecological environment benefit.

Description

technical field [0001] The technical field of agricultural fertilizers of the present invention particularly relates to a compound fertilizer for wheat and a preparation method thereof. Background technique [0002] Wheat is an important food crop in my country. Its sown area and total output are second only to rice, which is of great significance to the development of my country's agriculture. Fertilizer plays a very important role in the process of wheat planting, affecting the quality and yield of wheat. At present, most of the fertilizers used for wheat planting are nitrogen, phosphorus and potassium compound fertilizers. Although they can meet the growth needs of wheat in a short period of time, long-term use will damage the soil aggregate structure, which will easily cause soil compaction, soil hardening, and reduce soil fertility. At the same time, pure inorganic fertilizers have low fertilizer efficiency and cannot evenly distribute the various nutrients needed for ...
