Description

Cultured soil using coal bottom ash {plant growth medium}

The present invention relates to a cultivation soil for crop cultivation and seedling using coal floor material.

The coal ash produced by burning coal is divided into two types. One is fly ash, which is caught in the dust collector after most of it is burned and lightened, and the other is coal ash which is accumulated at the bottom of the furnace due to incomplete combustion. (bottom ash) In the case of fly ash, more than 80% is recycled. Among them, more than 76% is recycled as cement raw materials and ready-mixed concrete. In addition, in the case of coal floor ash, 74% of the 2007 generation amount is landfilled. Landfilling as described above is not economically and industrially desirable.

Until now, most coal ash has been mainly used in the civil construction field, but in the agricultural field, only the soil amendment and fertilizer raw materials are available.

On the other hand, agricultural use of bottom ash has many advantages that can be consumed in large quantities. Organic matters such as nitrogen, etc. contained in coal due to the combustion are lost, but in addition to Si, Fe, Ca, Mg, K, and other inorganic matters such as Mn and B, it is not only a beneficial source of essential minerals for crops, but also functional farming. It can be developed as a material. Therefore, it is necessary to actively develop the technology for high value-added eco-friendly agricultural materials as a way to drastically increase the recycling of bottom ash.

  The agricultural use of Bottom Ash not only takes into account the various factors affecting the soil environment and the growth of crops, but also requires the use of soil, fertilizer, The results of research on the functionality, efficiency and safety of coal floorings in various fields such as environment and crop growth should be derived. However, conventionally, the situation was not based on such research.

The present invention has been made in order to solve the above problems, it is an object of the present invention to provide a culture soil suitable for plant growth as a coal floor.

The cultured soil using the coal flooring material of the present invention for achieving the above object, in the cultured soil using the coal flooring material, the coal flooring material is neutralized flooring material, the volume% of the neutralized flooring material is 100% by volume of the cultured soil 40 to 100% by volume.

In addition, the neutralized flooring material; And a first topsoil selected from one of cocofit or peat moss.

In addition, it is characterized in that it further comprises a second topsoil selected from one of bark or vermiculite.

According to the culture soil using the coal floor material of the present invention as described above, there are the following effects.

First, better growth of plant cultivation is achieved than existing standard culture soil.

Second, it is possible to replace mineral material with coal floor material among existing culture soils.

Third, it is suitable for plant cultivation as culture soil using coal floor material.

Fourth, it is possible to expand the nutrient solution for cultivation, landscaping, and rooftop plant growth artificial culture soil.

Cultured soil using coal flooring according to a preferred embodiment of the present invention, the coal flooring is neutralized flooring neutralized flooring, the volume% of the neutralized flooring is characterized in that 40 to 100% by volume with respect to 100% by volume of the cultured soil do.

Referring to Figure 1, the moisture characteristics of the coal flooring is described as follows. Due to the characteristics of the seedling culture soil, moisture supply and air permeability must be satisfied at the same time. The coal floor has about 8.4% of the gaseous volume, which shows the gaseous content under the water tension of 1kPa. This shows the characteristic that a certain gas phase portion is distributed even when the water is almost saturated. This means that the moisture content in the condition of moisture tension 1 ~ 5kPa that the plant can absorb moisture with less energy, about 20% of the available moisture that can be easily used by the plant is also a smooth supply of moisture. It prevents the rapid change of various physicochemical properties such as dissolution of soil nutrients, pH, and temperature, that is, it is related to the buffering capacity of culture soil, and the buffer water between 5 ~ 10kPa of water tension shows 11.6%, showing good water storage capacity. . The optimum moisture potential is 5.5 kPa, which means the optimum condition of the permeability and moisture supply capacity of the topsoil, that is, 50% of the topsoil except the solid phase is filled with air, and the remaining 50% is filled with water. Shows good topological properties to secure the weather.

The coal bed ash below 2mm is neutralized with 0.8N nitric acid solution, and the coal bed ash above 2mm is determined as 0.15N nitric acid solution. The mixed coal floor is neutralized with 0.6N nitric acid solution.

○ Tap water raising seedling examination

  Acid neutralization is divided into nitric acid alone neutralization and nitric acid and phosphoric acid neutralization with the particle diameter of coal flooring less than 2mm. Nitrate neutralization is treated by mixing the volume ratio of coal bottom ash and 0.8 N dilute nitric acid solution at 5: 1, and the mixing ratio of nitric acid neutralizing bottom ash and cocoite is 4: 6, 6: 4, 8: 2, 10: 0 It is prepared in four kinds. 3 is an example in which the mixing ratio of nitrate neutralized flooring material and cocoite is 4: 6.

Nitric acid and phosphoric acid mixed neutralization is mixed with 0.8N nitric acid and 1.5N phosphoric acid solution at 7: 1 and then neutralized with coal bottom ash at a volume ratio of 1: 5. Mixed acid neutralized coal ash is prepared by mixing Coco pits with four types of 4: 6, 6: 4, 8: 2, and 10: 0. The pH ranges from 5.5 to 7.6.

Compared with the chemical properties of the prepared coal-bottom culture soils in Table 2, the neutralization treatment of nitric acid alone shows the effect of adding 1290 mg / l of nitrate nitrogen in the culture soil, and the mixed nitric acid and phosphoric acid neutralization treatment 1000 mg / N in the culture soil. It shows the effect of addition of 880 mg / l effective phosphoric acid. Therefore, the mixed acid neutralization floor material and coco peat 4: 6 mixed culture soils contain about 370 mg / l nitrogen nitrate and about 358 mg / l effective phosphoric acid, so that no nutrient-containing culture soils need to be added. .

I. Dentrobium

① Growth and nutrient content (7 months after the meal)

Unlike mysterium, dentrobiium has a low growth rate from 5 months after planting as the amount of coal floor ash is mixed, resulting in growth problems in the 100% coal bottom ash soil, especially mixed with phosphoric acid rather than neutralizing nitric acid alone. In acid neutralization, growth tends to be more suppressed.
