Amino acid long-acting formula fertilizer and preparation method thereof

Abstract

The invention discloses an amino acid long-acting formula fertilizer and a preparation method thereof. Urea, mono-ammonium phosphate and potassium chloride in the amino acid long-acting formula fertilizer are added into soil to provide sufficient nitrogen, phosphorus and potassium elements for the soil, ammonium polyphosphate, sodium polyacrylate, dicyandiamide and potassium humate in the long-acting mixture are macromolecular organic matters, the macromolecular organic matters can be combined with soil colloid, can be complexed with exchangeable aluminum, can slowly release nitrogen and phosphorus in the fertilizer and keep long-acting, and amino acid in the fertilizer can improve crop quality, reduce physiological diseases of crops, particularly can promote rapid growth of the crops andis remarkable in yield increasing effect. According to the preparation method, fertilizer drying and screening equipment is used for drying and screening mixed fertilizer particles, the mixed fertilizer particles are evenly dried through the drying mechanism and are high in drying efficiency, the obtained amino acid long-acting formula fertilizer is small in particle size and easy to disperse intosoil through the screening mechanism, and the fertilizing effect of the amino acid long-acting formula fertilizer is improved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to an amino acid long-acting formula fertilizer and a preparation method thereof. Background technique [0002] With the popularization of high-efficiency and high-yield agriculture, fertilizers play an important role in increasing agricultural production and income, especially with the promotion of fine agriculture, reasonable, precise and effective fertilization is a direction for the development of existing agricultural fertilizers. Existing formula fertilizers The development direction is mainly specialization, medicinal use and long-term effect. Specialization means that different crops have different special fertilizers, that is, targeted; medicinal use refers to the combination of fertilizers and pesticides, which can play multiple effects. Long-term effect refers to reducing the amount of fertilization, which can improve the utilization rate of fertilizer, save labor, time and eff...

Problems solved by technology

[0004] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a long-acting amino acid formula fertilizer and its preparation method: by mixing urea, monoammonium phosphate, potassium chloride, and long-acting mixtures, they are added to a pulverizer and pulverized to obtain Powder mixed fertilizer, spray the amino acid solution on the powder mixed fertilizer and mix evenly, then add the sprayed powder mixed fertilizer of the amino acid solution to the granulator to make mixed fertilizer granules, and then use the fertilizer drying and screening equipment to mix the mixed fertilizer granules Drying and sieving to obtain the amino acid long-acting formula fertilizer solves the problem that the existing formula fertilizer has insufficient long-acting effect, short-term failure affects crop growth, and the existing formula fertilizer has a large particle size and is not uniform enough, which is easy to agglomerate. It is difficult to disperse into the soil and affect the fertilization effect of the formula fertilizer
