Embodiment 1

[0028] A modified seaweed functional water-soluble fertilizer, comprising the following components in mass percent: urea 25%, diammonium phosphate 8%, potassium nitrate 62.65%, ethylenediaminetetraacetic acid chelated trace element fertilizer 0.15%, alkali-extracted seaweed 4% %, AT modifier 0.1%, phosphite 0.1%;

[0029] Its preparation method comprises the following steps:

[0030] Step 1: Weigh 25kg of urea, 8kg of diammonium phosphate, and 62.65kg of potassium nitrate, place them in a pulverizer and pulverize them to 200 mesh respectively, and prepare for use;

[0031] Step 2: Add 50kg of water to the reaction kettle, add 4kg of alkali-extracted seaweed to the reaction kettle and heat it, heat the seaweed solution to 50-60°C, then add 0.1kg of AT modifier to the reaction kettle and stir to keep the temperature constant After stirring and reacting for 10-15 minutes, add 0.15 kg of ethylenediaminetetraacetic acid chelated trace element fertilizer, and continue stirring and ...

Embodiment 2

[0035] A modified seaweed functional water-soluble fertilizer, comprising the following components in mass percent: 8% urea, 10% diammonium phosphate, 77.65% potassium nitrate, 0.15% ethylenediaminetetraacetic acid chelated trace element fertilizer, 4% alkali-extracted seaweed %, AT modifier 0.1%, phosphite 0.1%;

[0036] The preparation method is the same as that of Example 1, and a modified seaweed functional water-soluble fertilizer with a nutrient content of 13-6-40+TE is obtained.

Embodiment 3

[0038] A modified seaweed functional water-soluble fertilizer, comprising the following components by mass percentage: 13.6% of urea, 37.8% of diammonium phosphate, 44.25% of potassium nitrate, 0.15% of ethylenediaminetetraacetic acid chelated trace element fertilizer, and 4% of alkali-extracted seaweed. %, AT modifier 0.1%, phosphite 0.1%;

[0039] The preparation method is the same as that of Example 1, and a modified seaweed functional water-soluble fertilizer with a nutrient content of 20-20-20+TE is obtained.

Abstract

The invention belongs to the field of fertilizers, and particularly relates to a modified seaweed functional water-soluble fertilizer and a preparation method thereof. The fertilizer comprises the following components: 8-51% of a nitrogen fertilizer, 8-40% of a phosphorus fertilizer, 20-78% of a potassium fertilizer, 0.1-0.2% of a trace element fertilizer, 2-4% of seaweed, 0.1-0.2% of an AT modifier, and 0.1-0.2% of a stabilizer, wherein the AT modifier is prepared by compounding organic acids and alkylphenol ethoxylates. According to the invention, a scheme of mixing alkaline seaweed with macroelements, medium elements and trace elements is adopted, so that the problem of acid-base mixing between seaweed and a macroelement water-soluble fertilizer is solved, organic nutrients and inorganic nutrients are combined, the growth of crops can be activated during fertilization, the growth vigor of the crops is improved, and the quality and yield of the crops are improved; meanwhile, the organic nutrients also have an improvement effect on the soil, and rich absorbable organic nutrients are provided, so that the seaweed and the macroelement, medium element and microelement water-soluble fertilizers have a mutual synergistic effect.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a modified seaweed functional water-soluble fertilizer and a preparation method thereof. Background technique [0002] With the continuous development of modern agriculture, people's requirements for the output and quality of various economic crops continue to increase, and the planting industry often chooses to increase the input of fertilizers to increase crop output. However, increasing the input of fertilizer not only increases the yield, but also destroys the soil environment, which makes the soil acidification and hardening more serious, the soil problem is serious, the growth of the crop root system is not good, and the crop yield will be affected. The fertilization method with large fertilizer input has caused a vicious cycle: increasing fertilizer input increases production while destroying the soil environment. The soil is destroyed and leads to poor growth and pr...
