According to the present invention, water-soluble sodium silicate is produced by melting and pulverizing waste glass classified into environmental pollutants and pulverizing waste glass and silica sand (SiO ₂ ) and anhydrous sodium carbonate (Na ₂ CO ₃ ) to maintain soil neutralization. By mixing the trace elements with high temperature melting, the soil is contaminated with acidified soil and fertilized by excessive fertilization of chemical fertilizers using the basic development factors of the crops, which have the effects of silicic acid and silicate on environmentally friendly soil improvement and plant growth. The present invention relates to a method for preparing an inexpensive agricultural plant growth agent that improves the soil to neutrality and strengthens the stems and leaves of the plant through side fertilization, thereby increasing the disease resistance and greatly affecting the yield increase.

Agricultural plant growth agents have been researched and developed in academia for a long time and are now commercialized, and many patents and studies have been published. If some patents are introduced, Korean Patent No. 0522894 describes a composition for improving plant growth, using environmentally friendly materials as a main ingredient, wherein chitosan, wood vinegar, brown rice vinegar, and antagonists are added as main ingredients. In Claim 5, copper, boron, iron, manganese, molybdenum, and zinc were added as a water-soluble metal component. In addition, it describes a method of preparing a composition in which the germanium alumite (SiO ₂ ) raw mineral of Korean Patent No. 0259790 is pulverized to mix water-soluble iron, manganese, zinc, boron, molybdenum and copper. In addition, Korean Patent No. 0350101 describes granular siliceous soil modifiers based on anhydrous acidic acid (SiO ₂ ) and zeolite, and the siliceous fertilizer composition of Korean Patent No. 0415594 includes one type of silicic acid (SiO ₂ ), alkali carbonate, and phosphorus compound. Selected above, the manufacturing method of melt-cooled pulverization at melting temperature 1,500-1,700 degreeC is listed.

Agricultural plant growth should be easily soluble in crops as it is water-soluble because it distributes evenly the large amount of elements and trace elements necessary for plant growth.

The present invention, which is completely different from the above patents, has a beneficial effect on the environment, and has the effect of one stone and _two groups of silicic acid in which the alkali component of silicic acid (SiO ₂ ) containing waste glass is mainly contained as waste glass, which is environmental waste. By using the effect, it improves acidified soil and contaminated soil to neutral by excessive fertilization of chemical fertilizer, and strengthens the stem and leaves of plants to increase the disease resistance. ₂ SiO ₃ ) to develop eco-friendly and low-cost plant growth agent.

Silicate (Si) is an element that forms the basic mineral and occupies 28% of the earth's crust following oxygen. Silicic acid is dissolved by the interaction of weather, soil physical and chemical resistance, the molecules according to the soil _{pH (H 4 SiO 4, H} 3 SiO 4 -, H 2 SiO 4 2-, HSO 4 3- and SiO ₄ ^4- ) And polysilicic acid (n (SiOH ₄ )), Al, Fe, Ca, Na, MgSO ₄ and other inorganic compounds, and organic silicic acid complexes. Plants are mainly absorbed by H ₄ SiO ₄ form, the ionic form is inhibited by other ions and antagonists. Monosilicic acid and polysilicic acid, which plants mainly absorb, affect soil pH through the interaction of both. The amount of silicic acid in paddy soil is 130 ~ 180 (mg / kg), but the silicic acid content in Korea is 86 (mg / kg), which means that 84.4% of paddy fields lack silicic acid. In rice farming, rice grows by absorbing more than eight times the amount of silicic acid. Silicate has the effect of suppressing the onset of rice blast, white leaf disease, and paperback disease, and also serves as a preventive effect on various vegetables and fruit trees, and also reduces soil pollution. In particular, the effects of silicic acid application have been recognized by many researchers about blasting disease.In the cold districts, if the silicic acid concentration of the oil-forming leaves is 5% or higher, the leaf heating and the extractor concentration of 8% or more are significantly suppressed. It is said to be possible. This disease resistance has been attributed to silicic acid deposited in the epidermal tissue of crops to physically prevent the invasion of pathogens. Recent studies suggest that silicic acid accumulates on the invasion of blast germs and is not found in other nutrients. It has been found to be essential for plant growth by having properties and promoting the production of free radicals. When silicic acid accumulates on stems and leaves, the tissues are robust, and thus the resistance to doping and resistance to pests is contributed to the yield by good ripening and quality improvement.

Soluble sodium silicate (Na ₂ SiO ₃ ) is absorbed by the roots and rises in the plant. As the leaf evaporates, the silicon of the foliage is deposited in its epidermal cell membrane to become siliceous cells, making the plant robust. Because of this, many germs and other germs that have adhered to the plant are not easily invaded into the inside of the plant, but even if they are invaded, the development of the crab is usually suppressed, the lesions do not grow, and the number thereof is reduced, and silicic acid is accumulated in the cells of the plant. It increases the physical strength of the leaves and makes the stems and leaves of the plant stand upright so that the photosynthetic efficiency due to the light absorption of the leaves is prevented, so that the infection of the dobok and germs can be prevented, the disease resistance against insects is increased, and it is strong against the East Sea. .

The plant growth growth agent of the present invention has an infinite value in terms of environmental aspects by recycling waste glass by replacing water-soluble silicate with the waste glass, which is the main culprit of environmental pollution, even after millennia. have.

It is an object of the present invention to improve the acidic soil by supplying the plant growing agent made of water-soluble sodium silicate (Na ₂ SiO ₃ ) to the farm at low cost by melting the waste glass which is environmental waste together with the additives, and strengthening the roots strongly. It strengthens the crops, strengthens the stems and leaves of plants, suppresses the excess absorption of nitrogen, and provides granular, powdery, and liquid plant growth agents that contribute to the increase of harvest with resistance to germs such as blasting and cold.

The chemical reaction that is already in the melting process when the waste glass (SiO ₂ ) is melted by using a collet melted with a mixture of sodium carbonate (Na ₂ CO ₃ ) in the waste glass which is the main component of the present invention. Since it is completed, it consumes less energy, melts at the initial flame temperature of the blast furnace, and has the effect of preventing the scattering of the raw materials to be added and mixed together. A homogeneous melt can be obtained. By manufacturing 12 hours with 4 hours of melting, it has been advantageous to shorten the melting time, save a lot of energy, reduce the cost, and synergistic effects of environmental rehabilitation products.

The plant growth growth agent of the present invention contributes to soil improvement and plant growth by utilizing waste resources from environmental pollution, improves acid soil by contacting with moisture with photosynthetic alkaline components, promotes the growth of crops, and is most beneficial for animal and plant living organisms. Emissivity of 5 ~ 20 microns in the wavelength range of far infrared ray in 92% facilitates metabolism of crops and promotes crop growth.

Reference will now be made in detail to the accompanying drawings of the present invention.
