Embodiment 1

[0025] Send the compound amino acid solution accounting for 60% of the total amount with a content of 10-25% into the chemical reaction kettle, carry out solid-phase crushing treatment on the trace elements accounting for 1% of the total amount, and then send it into the chemical reaction kettle, start the agitator to stir, At normal temperature, the chelation reaction begins. At this time, the pH value should be monitored all the time. Use an appropriate amount of sodium hydroxide aqueous solution to control the pH value to 5. The chelation reaction time is 8 hours. After the chelation reaction is completed, add 1% of the total amount of Stabilizer and controlled-release agent accounting for 1% of the total amount, after stirring evenly, add potassium fulvate which accounts for 5% of the total amount and stir evenly to obtain the liquid part of the fertilizer; send the mineral fertilizer accounting for 32% of the total amount to Put it into a nano-scale pulverizer to pulverize...

Embodiment 2

[0027] The compound amino acid solution accounting for 61.875% of the total amount and containing 10-25% is sent into the chemical reaction kettle, the trace elements accounting for 1% of the total amount are solid-phase crushed and then sent into the chemical reaction kettle, and the stirrer is started to stir. At normal temperature, the chelation reaction begins. At this time, the pH value should be monitored all the time. Use an appropriate amount of sodium hydroxide aqueous solution to control the pH value to 5. The chelation reaction time is 8 hours. After the chelation reaction is completed, add 1% of the total amount of Stabilizer and controlled-release agent accounting for 1% of the total amount, after stirring evenly, add potassium fulvic acid which accounts for 5% of the total amount and then stir evenly to obtain the liquid part of the fertilizer; send the mineral fertilizer accounting for 30.125% of the total amount to Put it into a nano-scale pulverizer to pulveriz...

Embodiment 3

[0029]The compound amino acid solution accounting for 63.75% of the total amount and the content of 10-25% is sent into the chemical reaction kettle, and the trace elements accounting for 2% of the total amount are solid-phase crushed and then sent into the chemical reaction kettle, and the stirrer is started to stir. At normal temperature, the chelation reaction begins. At this time, the pH value should be monitored all the time. Use an appropriate amount of sodium hydroxide aqueous solution to control the pH value to 5.5. The chelation reaction time is 7.5 hours. After the chelation reaction is completed, add 1% of the total amount of Stabilizer and controlled-release agent accounting for 1% of the total amount, after stirring evenly, add potassium fulvate which accounts for 4% of the total amount and then stir evenly to obtain the liquid part of the fertilizer; send the mineral fertilizer accounting for 28.25% of the total amount to Put it into a nano-scale pulverizer to pul...

Abstract

The invention discloses an amino acid liquid mineral fertilizer wrapped by microcapsules and a preparation method of the fertilizer, and belongs to the field of fertilizer production. The preparation method comprises the steps that 60%-75% of composite amino acid liquid with the content ranging from 10% to 25%, 1%-5% of medium trace elements, 1%-5% of potassium fulvic acid, 17%-32% of mineral fertilizer, 1% of stabilizer, 1% of release controlling agent and an appropriate amount of sodium hydroxide aqueous solution are taken as the raw materials, production and microencapsulation of liquid fertilizer and solid fertilizer are conducted, and a finished product is obtained. The production method and the product have the advantages that the production cost is low, energy conservation and environment friendliness are achieved, the water-retaining capacity is high, nutrient elements needed by crops can be provided, besides, the effects of adsorbing heavy metal and morbid substances in soil, balancing soil nutrients, activating soil vigor, promoting metabolism of the crops and improving resistance and immune function of the crops can be achieved, the yield is generally increased by about 20%, the effects of improving drought resistance, premature aging resistance and continuous cropping resistance of the crops can be achieved, and the amino acid liquid mineral fertilizer is a pure natural product and free of toxic and side effects.

Description

Technical field: [0001] The invention belongs to the field of fertilizer production, in particular to an amino acid liquid mineral fertilizer produced by encapsulating microcapsules. Background technique: [0002] The product of the present invention is a microencapsulated amino acid liquid mineral fertilizer, and its components mainly include four categories, the first category is compound amino acid, the second category is medium and trace elements, the third category is mineral fertilizer, and the fourth category is yellow Potassium humate. Compound amino acid is an essential nutrient for plant growth. Due to the characteristics of amino acid itself, it has a unique role in promoting plant growth, especially photosynthesis. Plant chlorophyll content, increase enzyme activity, promote the penetration of carbon dioxide, make photosynthesis more vigorous, improve crop quality, increase the content of Vc and sugar, increase the accumulation of dry matter and the speed of ope...
