Problems solved by technology

However, the cation activator used in this ion activator has certain limitations for fertilizers such as monoammonium phosphate that need to use acid radical ions, which makes it difficult for anions to form a free state, and it is difficult for crops to absorb and utilize them.

Embodiment 1

[0026] The formula of acid monoammonium phosphate fertilizer of the present invention is as follows:

[0027] 90kg monoammonium phosphate, 10kg citric acid monohydrate, 1.0kg sodium cetyl sulfonate.

[0028] Acid monoammonium phosphate fertilizer preparation method of the present invention is as follows:

[0029] Add 90kg of crushed monoammonium phosphate, 10kg of citric acid monohydrate, and 1.0kg of sodium hexadecylsulfonate in turn into the production tank and mix them thoroughly. The three need to be added in sequence. Because the monoammonium phosphate has been agglomerated, it needs to be pulverized first.

Embodiment 2

[0031] The formula of acid monoammonium phosphate fertilizer of the present invention is as follows:

[0032] 11kg citric acid monohydrate, 89kg monoammonium phosphate, 0.5kg sodium cetyl sulfonate.

[0033] The preparation method of acid monoammonium phosphate in the present embodiment is identical with embodiment 1.

Embodiment 3

[0035] The formula of acid monoammonium phosphate fertilizer of the present invention is as follows:

[0036] 13kg citric acid monohydrate, 87kg monoammonium phosphate, 1.5kg sodium cetyl sulfonate.

[0037] The preparation method of acid monoammonium phosphate in the present embodiment is identical with embodiment 1.

Abstract

The invention provides an acidic monoammonium phosphate fertilizer composed of the following substances including monoammonium phosphate, citric acid and an anionic active agent. A preparation method of the acidic monoammonium phosphate fertilizer comprises the steps of sequentially adding the smashed monoammonium phosphate, citric acid and anionic active agent into a tank, and sufficiently stirring and uniformly mixing to obtain the acidic monoammonium phosphate fertilizer. The acidic monoammonium phosphate fertilizer disclosed by the invention is suitable for all crops; and because of being an acidic fertilizer, the acidic monoammonium phosphate fertilizer is suitable for application in alkaline soil and capable of effectively improving saline soil and has the optimal application effect on crops such as rice liking an acid environment.

Description

technical field [0001] The invention belongs to the technical field of inorganic fertilizers, in particular to an acidic monoammonium phosphate fertilizer. Background technique [0002] After the chemical fertilizer boom in the world in the middle and late 20th century, nitrogen fertilizers were used, which played a great role in agricultural production. After a period of time, it was found that the soil was deficient in phosphorus, so calcium superphosphate and diammonium phosphate were used in large quantities, and then Potassium deficiency in the soil appeared again, and potassium fertilizers were applied again, resulting in over-reliance on chemical fertilizers in agricultural planting. According to statistics from the Food and Agriculture Organization of the United Nations, my country's consumption of chemical fertilizers and pesticides accounted for 31% of the world's total in 2010, far higher than the share of grain production in the world's total grain production (19...
