Embodiment 1

[0051] Melt 435 parts of urea at a high temperature to about 140°C, enter the buffer tank, pressurize it through a delivery pump, and pump it into the top mixer;

[0052] After measuring 40 parts of potassium dihydrogen phosphate, 245 parts of potassium chloride and 280 parts of monoammonium phosphate, they are sent to the mixer and mixed evenly. After the mixed raw materials are crushed and sieved, they are sent to the mixing heater and heated to 90 At about ℃, it is sent to the silo at the top of the tower with a bucket elevator;

[0053] The hot mixture in the tower top silo is measured by a spiral weighing scale and sent to the above tower top mixing tank, mixed by a high-speed shear mixer to make a thin paste material, the temperature is controlled at about 110°C, and filtered out by a vibrating filter After the particles impurity overflow to the granulation nozzle, under the centrifugal force of the rotation and shearing of the nozzle, the mixture is evenly sprayed into ...

Embodiment 2

[0056] Get 430 parts of urea, 100 parts of potassium dihydrogen phosphate, 210 parts of potassium chloride, 220 parts of monoammonium phosphate, and 40 parts of humic acid as raw materials, and the production process is the same as in Example 1;

[0057] The obtained product specification is N-P 2 o 5 -K 2 O(22-16-16), containing humic acid, without trace elements.

Embodiment 3

[0059] Take 440 parts of urea, 100 parts of potassium dihydrogen phosphate, 210 parts of potassium chloride, 220 parts of monoammonium phosphate, 10 parts of EDTA chelated iron, 10 parts of EDTA chelated zinc, and 10 parts of EDTA chelated manganese as raw materials. The production process is the same as Embodiment 1;

[0060] The obtained product specification is N-P 2 o 5-K 2 O(22-16-16), does not contain humic acid, contains trace elements.

Abstract

The invention discloses a high-concentration humic acid type chelated multi-trace element special fertilizer for wheat and a production method thereof, belonging to the technical field of fertilizers. The production method comprises the following steps: preparing urea, potassium dihydrogen phosphate, potassium chloride, monoammonium phosphate, humic acid, EDTA (ethylene diamine tetraacetic acid) chelated iron, EDTA chelated zinc and EDTA chelated manganese according to specified proportions; melting the urea at high temperature, pressurizing, evenly mixing with the other raw materials, crushing, screening, heating, preparing paste, carrying out vibratory filtration, carrying out spray molding, cooling, screening, carrying out anti-agglomeration treatment and packaging. The special fertilizer follows the law of wheat for nutrient absorption, has the advantages of comprehensive nutrients, balanced fertilizer components, higher fertilizer efficiency and higher fertilizer utilization ratio, reduces the environmental pollution, enhances the stress tolerance and enhances the wheat quality.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a high-concentration humic acid-type chelated polymicro special fertilizer for wheat and a production method thereof. Background technique [0002] Wheat is one of the most important food crops for human beings, and is the staple food of 1 / 3 of the world's population. In my country, wheat is the second largest food crop after rice, and its planting area and total output rank first in the world. [0003] Some important micronutrient elements (iron, zinc, manganese, etc.) in wheat grains are often deficient or low in content, resulting in about 3 billion people in developing countries around the world who are currently facing potential micronutrient deficiency "hidden hunger" ” threat, especially in economically underdeveloped regions, where one-third of children and women exhibit key micronutrient deficiencies (iron, zinc). The long-term lack of trace elements in the human bo...
