DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizer for supplying nutrients to plants, and more particularly to a slurry fertilizer which can contain various components and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, fertilizers include solids, liquids, and the like, but there has been a compound liquid fertilizer containing many types of components as a material capable of rapidly absorbing many types of components at once. Multiple solutes (fertilizer components) in solvents such as water
Is a solution in which is dissolved.

[0003]

Such a lysing solution is
A saturated solution may be formed due to chemical or physical factors. For example, quantitative balance of multiple solutes, solute
A saturated solution state may be obtained depending on the PH value or a decrease in the temperature of the solution. When it comes to a saturated solution state,
A chemical change occurs in a part or the whole amount of the solution to precipitate some compound from the solute or to generate a precipitate. If such a change occurs, it may cause physical problems when used as fertilizer, or
The effect of the original fertilizer component cannot be obtained. Therefore, the present invention provides a high concentration fertilizer solution obtained by dissolving a fertilizer component in a solvent,
It is an object of the present invention to obtain a stable fertilizer by suppressing the occurrence of a chemical change in a saturated solution state after preparation.

[0004]

The slurry fertilizer of the first invention is characterized by comprising a solution in which various fertilizer components are dissolved, peat moss absorbing the solution, and a paste. According to a second aspect of the present invention, a fertilizer solution is prepared by dissolving various fertilizer components in a solvent charged into a tank. A predetermined amount of peat moss is poured into the fertilizer solution, and the fertilizer is inserted into pores of cells that organize the peat moss. Absorb the lysate, then
This is a method for producing a slurry-like fertilizer, in which a predetermined amount of paste is administered and stirred.

[0005]

[Function] A fertilizer solution is prepared by dissolving various fertilizer components in a solvent, and a predetermined amount of peat moss is introduced into the fertilizer solution.
The above fertilizer solution is absorbed into the pores of the cells forming the peat moss, and then a predetermined amount of paste is applied to obtain a slurry fertilizer. The fertilizer solution in the slurry fertilizer, even at a high concentration, is retained in the pores of the peat moss cell group and is blocked by the paste, so that the solute in the solution may cause a chemical reaction. Will be shut off. Therefore, it can be stored in a stable state. And in the soil, in the soil solution, the paste is dissolved,
Next, the fertilizer components are gradually eluted and dispersed. The peat moss used here is an organic soil on which a certain type of moss is deposited, which grows naturally in cool regions such as Northern Europe,
The cell pores constitute an open cell tissue. These cell pores can absorb and store 10 to 15 times as much water as dried peat moss by weight.

1 to 3 show a method for producing a slurry fertilizer containing a plurality of fertilizer components. The production process shown in FIG. 1 includes a preparation tank 1 for charging and preparing raw materials.
, A slurry tank 2, a filling and measuring machine 7, a pipe 3 connecting them, stirrers 4 and 5 installed in each tank,
A roller conveyor 9 for conveying the product 8 is provided.
The method for producing the slurry fertilizer will be described with reference to the flowchart of FIG. In addition, the raw material prescription of the slurry-like fertilizer of this example is as shown in the sample A of the table of FIG. The solvent is
Water and fertilizer, which is a solute, contain N, P, and K, respectively, by 46%, 64%, and 80%, respectively. By setting the input amount of the fertilizer to 54:39:31, N, P, and K become the same components (25 parts by weight). Also, peat moss has a dry weight of 10%.
Since it absorbs up to 15 times as much water, 7 parts by weight of this example absorbs about one third of the total solution.

First, as a step 1, water as a solvent is charged into the preparation tank 1. Next, fertilizer is charged as a fertilizer component N, which is a solute, and stirred (Step 2,
3). Similarly, add fertilizer and fertilizer. As described above, when a plurality of fertilizer components are contained, Steps 2 to 4 are repeated. When the solute is dissolved, heat of reaction may be generated. In such a case, the temperature is set to room temperature by leaving or cooling (Step 5), peat moss is added, and the mixture is stirred (Step 6, 7). Peat moss is vulnerable to heat, and if it is heated to 60 ° C. or higher, the tissue will be destroyed. When the peat moss has sufficiently absorbed the lysate, steps 8 and 9
Is added and stirred with sodium polyacrylate as a paste. At this time, if the total amount of the peat moss is not added at once, but if it is divided into several times, the absorption of the solution will be quicker.
After repeating step 10, go to step 11. The solution sent to the slurry tank 2 is the slurry fertilizer of the present invention.

[0008] The slurry-like fertilizer in the slurry tank 2 is sent to a filling and weighing machine 7 and the product sealed in a fixed quantity container is converted into a product 8.
(Steps 12 and 13). Product 8 in this way
Slurry fertilizer hardly flows in the container during storage and transportation, and is stored and sealed in the myriad cell pores of peat moss, thereby suppressing chemical change. When this slurry-type fertilizer is actually used in various soils or hydroponic liquids, the film of the paste that blocks the fertilizer solution filled in the pores of the peat moss cells forms a soil solution or hydroponic liquid. To elute. Next, the plurality of fertilizer components stored in the water pores of the cells are gradually penetrated into the soil or the hydroponic solution to be useful for plant growth. The paste used here is a water-soluble paste such as dextrin or sodium alginate, in addition to sodium polyacrylate. Further, since peat moss is a natural high-quality organic substance, even after releasing the fertilizer component from the pores, the peat moss becomes an effective soil component as a humus. As shown in FIG. 3, the dissolving solution in which the fertilizer components are dissolved has a considerably high concentration, and as it is, the concentration may become saturated due to the temperature drop. By keeping the same, a chemical change as a saturated solution can be suppressed.

For example, an experiment was carried out to confirm the stability of the slurry fertilizer of the present invention shown in FIG. 3 as Sample A, and a fertilizer solution prepared by removing peat moss and paste from this formulation as Sample B. . When 200 ml of each of Samples A and B were placed in a transparent plastic bag and allowed to stand at 4 ° C. (conditions), needle-like and granular crystals were precipitated in the bag of Sample B. Could not do such a thing. When the temperature was further lowered to 0 ° C., the sample A was not changed. Here, the presence or absence of precipitated crystals
In addition to being visually observable, it can be confirmed by touching the bag. In addition, the amount of peat moss or paste added increases, the higher the viscosity, the lower the flow efficiency due to tube resistance, but the higher the chemical stability of the fertilizer solution. desirable. Further, in the present embodiment, a plurality of components are sequentially charged into one preparation tank 1 for preparation. However, a slurry can be mixed using a different preparation tank for each fertilizer component and then mixed.

[0010]

Industrial Applicability According to the present invention, a slurry fertilizer solution containing peat moss, which contains a plurality of fertilizer components and forms humus useful for plants, can be obtained. In addition, the slurry fertilizer solution was able to suppress chemical changes caused by various factors and to be stable.
