Problems solved by technology

[0003] Generally, mineral liquid fertilizers are made by crushing various inorganic substances containing minerals, acid treatment, adding them to an aqueous solution or treating them with an acidic aqueous solution for a certain period of time. In the state of such a mineral water solution, minerals will aggregate, precipitate, and undergo chemical reactions to deteriorate during preparation or storage. It is difficult to prepare and the effect is not good when it is used as a fertilizer. It needs to be cleaned frequently, which not only causes inconvenience in use, but also has the problem of long-term storage

preparation example Construction

[0103] A method for preparing fertilizers made from seawater, comprising the steps of:

[0104] Step 1. Prepare mineral concentrated water, sulfur water production solution, Illite or sericite water production solution, water-soluble nitrogen, water-soluble boron, and water-soluble zinc respectively:

[0105] To prepare mineral water concentrate:

[0106] (1) Mixing seawater or natural salt brine with water, allowing the content of seawater or natural salt brine to reach 20-25% by weight, removing foreign matters after filtering with a filter of 100-200 meshes to extract filtered water;

[0107] (2) Put the filtered water in step (1) into a steamer and heat at a low temperature of 40-60°C to precipitate salt;

[0108] (3) Put the filtered water in step (2) into a dehydrator to separate the salt and mineral stock solution;

[0109] (4) After filtering and concentrating the mineral stock solution in step (3) on an activated carbon filter device, the concentrated seawater with ...

Embodiment 1

[0124] 1. Preparation of concentrated mineral water: mix seawater with water, the content of seawater is 25% by weight, and the mixed water is filtered with a 100-mesh filter to obtain filtered water, and the obtained filtered water is heated in a steamer at 50°C After recrystallization and precipitation of salt, put it into a dehydrator to separate the salt and mineral stock solution, and filter and concentrate the separated mineral stock solution through an activated carbon filter device to prepare 40Brix mineral concentrated water.

[0125] 2. Preparation of water production solution of sulfur: mix detoxified sulfur and kelp powder with water, and then disperse them with a nano-mixer to prepare an aqueous solution of detoxified sulfur containing 15% by weight of detoxified sulfur with an average particle size of 1 μm, wherein the kelp powder is added The amount is 0.1% by weight.

[0126] 3. Preparation of Illite's water production liquid: mix Illite powder, kelp powder and...

Embodiment 2

[0132] Except that seawater is replaced by brine of natural salt, other methods are the same as in Example 1 to obtain liquid fertilizer.

Abstract

The invention discloses a fertilizer made of seawater. The fertilizer comprises 80-91.7wt% of mineral substance concentrated water, 2-5wt% of a moisture liquid of sulfur, 5-10wt% of a moisture liquidof Illite or sericite, 0.1-0.5wt% of kelp powder, 1-9wt% of water-soluble nitrogen, 0.1-2wt% of water-soluble boron and 0.1-2wt% of water-soluble zinc. The invention further discloses a method for preparing the fertilizer made of the seawater. A mixing ratio of the liquid fertilizer disclosed by the invention is still kept after a certain time, even if mineral substances are massively provided, obstacle caused by excessive mineral substances can be avoided, plant growth can be promoted, and a remarkable effect can be achieved even if a small amount of the fertilizer is used. By adopting the liquid fertilizer disclosed by the invention, the sugar degree of a crop can be increased, the crop quality can be improved, and economic output values can be increased.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer made from seawater and a preparation method thereof. Background technique [0002] Generally, according to Liebig's least amount rule, plants selectively absorb various elements on the basis of the smallest amount of elements among all the elements that can be absorbed by themselves. Therefore, if there is a lack of trace elements and mineral components, even if organic fertilizers containing nitrogen, phosphorus, and potassium are fully provided, it can only promote soil acidification, and various components necessary for growth cannot be effectively absorbed. In addition to the ingredients, it needs to be infused with a continuous mineral composition. In the field of agriculture and horticulture, researches on fertilizers that can effectively provide such mineral components are intensively carried out. [0003] Generally, mineral liquid fertilizers are made b...
