Description

Method of manufacturing horticultural soil pumice

The present invention relates to the manufacture of soil pumice for cultivation of horticultural crops, in particular, the ability to increase the fertility and moisture retention, which is necessary for plant growth during potted planting.

Specifically, kaolinite-based clay, redite, haloysite-based batt, vermiculite-based clays, talc, dolomite, etc. Combining several kinds of inorganic materials, crushing and dehydration, and molding and drying the product by vacuum drilling and firing at high temperature to improve moisture retention and improve breathability such as oxygen supply. Aseptic pumice soil pumice can be obtained to increase the physicochemical properties of the soil.

According to the reported literature, it is known that physicochemical soil composition such as good nutrient retention and air permeability is very important in the cultivation of potted plants of horticultural crops because it grows in a limited area of cultivated soil.

It is also found to be almost absolute in terms of conservation of the "Rhizosphere" to enhance the oxygen supply and water retention necessary for plant growth.

Previously, "agricultural and horticultural soil compositions" consisting of "peat, lignite, quicklime, and soil microbial preparations" have been known, but this is mainly for the supply of nutrients suitable for plant growth. There is a drawback that leads to acidification.

The present invention is different from the above-described known technology, while providing sufficient air and moisture to plant roots in a limited area of soil and at the same time supplying nutrients, it is important to provide pumice soil that can promote growth by improving root development. The purpose was.

Another object of the present invention is to provide a composition of pumice soil suitable for potted planting, in particular by the composition of several kinds of pure minerals.

In fact, for the present invention, morphological experiments and physiological experiments were conducted. The morphological experiments can maintain suitable soil voids so as not to damage the roots of plants, and can be harmonized with any pollen. The physiological experiment focused on the growth promoting effect by improving the respiration of the roots by supplying sufficient moisture and air to the roots.

The raw materials and manufacturing method used in the present invention are mainly composed of kaolin, montmorillonite and iron minerals in Cheonwon-gun, South Chungcheong Province (Haterite) and Haloysite (Halloysite.Si ₂ Al ₂ O ₅ (OH)). Kaolinite (Kaolin ite.Si ₂ Al ₂ O ₅ (OH) ₄ ) near minerals in Sancheong, Gyeongnam, is based on clay and vermiculite of Hampyeong-gun, Jeonnam, the main minerals, and kaolin and mica ( Scotch (or chaff, charcoal, bark), manganese dioxide (Mno ₂ ), bone ash and borax in Mt. Pottry stone, talc and dolomite , Pb ₃ O ₄ was added to pulverize the combined raw materials by 150-200 mesh in a ball mill and dehydrated by a filter press. It was loaded in a kiln and heated at 1250 ℃ for 12 hours, followed by quenching (air type) or Cooling the soil and get pumice composition according to the invention is composition of the combination of the raw materials

In the present invention, a siliceous raw material was included in order to promote the pore phenomenon of the particles, which is defined as a repeating pattern in a two-dimensional or three-dimensional space forming a line or plane called a "lattice". The pumice and pumice water supply was smoothly arranged in a regular arrangement. A "lattice" is called a unit lattica, and ions, atoms, molecules, etc. are regularly arranged in a lattice point (crystal structure), and some contact arrangements are distorted due to irregular pressure during molding. .

Since the clay mineral in the present invention has a surface area of 45 m 2 / gr, it has a high adsorption force and forms a clay particle layer, which forms a fine capillary phenomenon in the product of soil pumice, which also causes a planar phenomenon to increase the solid volume itself. The total skin of solids and liquids is reduced and plasticity is increased during molding, increasing the dry strength. In addition, magnesia raw materials (Dolomite and talc) are included in the raw materials, which are not swelled by water or organic solution, do not dissolve in acid, and alkali resistance, so they do not chemically erode and coexist with alumina and silica. by reaction of the system and the thermal expansion coefficient of the plastic to create a small cordierite _{(Codierite. 2MgO.2Al 2 O 3.} 5SiO 2) and mullite (3Al ₂ O ₃ mullite. 2SiO ₂₎ was to facilitate the geupyeol quenching. Since the melting temperature of alumina (Alumina. Al ₂ O ₃ ) is high temperature of 2050 ℃, Fe ₂ O ₃ , MnO ₂ , CaO, KNaO, TiO ₂ inherent in raw materials are used to lower the melting point. In order to lower the chemicals such as borax, photo list and the like were used.

In addition, the use of vegetable materials such as sawdust within 2% is indispensable for forming a capillary phenomenon that can continuously supply moisture and nasal power, but when used in excess, the pores become too large, and thus the strength of the product becomes weak and plastic. This makes it difficult to mold due to the reduction of water supply, and it is impossible to continuously supply moisture and nutrients, which makes it impossible to maximize the excavation of soil pumice.

Bone ash, light end, and borax increase the sintering strength of the joints connecting the technicians and are used for the purpose of lowering the firing temperature during the firing of the product. Manganese (MnO ₂ ) reacts with the impurities in the raw materials to harmonize with plants and flower pots. It is used to indicate possible color, but can be replaced with other materials.

This large amount is formed and the moisture moisturizing power is 120-170% (measured after immersing 100 g in the ground water for 60 minutes), and it can be confirmed that a capillary phenomenon with good water transfer power is formed, and the moisturizing period is 20 days It has ~ 30 days and has a specific effect for plant growth and maintenance, but also has good strength and no breakage or scattering to keep the pores to the maximum, thereby preventing root rot and promoting growth according to moisture supply proportional to oxygen supply.

The disappearance test results of soil pumice according to the present invention are as follows.

Experimental Example 1

Western egg 씸 Bidium;

The cultured soil of orchids, including 란 vidium, has good breathability, moderate moisturizing power, and good drainage so that it can grow vigorously. It should also be capable of maintaining a certain amount of inefficiency. Since the culture soil having the above performance has not yet been developed in Korea, it is currently used as a culture soil for eggs by collecting natural clusters (Scoria) in the volcanic region of Jeju Island. However, the current law for the protection of nature is prohibited from taking such natural clusters. Therefore, the cultured soil of eggs is in the situation to be marketed and produced. In view of this, two-year seedlings (medium 40.5㎝, 9 leaves, 92.5g live weight) with a meistem tip culture were measured to measure the effect of the egg culture soil of the present invention. Compared with the control group, the soil pumice soil treatment group increased the fresh weight of Ovidium vividium by 14.5%, increased the weight gain by 16% and the bulb weight by 18.9% (Table 1).
