Description

A artificial seed growing soil for slope applies Polymer PVA}

The present invention relates to a surface greening material for stabilizing the inclined surface of the incision, and more particularly, it is possible to maintain a proper amount of water essential for the germination and growth of plants in the greening of the surface in a timely manner to absorb seeds The present invention relates to a frontal greening material using super-absorbent polymer PVA, which can greatly increase effective moisture, allow easy germination, and prevent soil solidification, thereby increasing the growth rate of plants.

PVA (Polyvinyl Alcohol) has a unique property of water solubility among synthetic polymers. It is a white powder with specific gravity of 0.3 ~ 0.7, thermal stability and thermoplasticity of 100 ~ 140 ℃ and no change in appearance with a short heating time, but structural change starts around 151 ℃ and gradually it is colored. Decompose at around 300 ℃. It is soluble in hot water (above 75 ℃) but swells only in cold water. Swell or dissolve in acid and alkali. The mechanical properties of the thin film are excellent in tensile strength, tensile strength, elongation and wear resistance than other synthetic resins. Gas permeability is good but water vapor is exceptionally permeable. It has hygroscopicity and excellent moisturizing power. The mechanical and electrical properties vary greatly depending on the external humidity. PVA aqueous solution does not deteriorate during storage.

Moreover, it is also used to improve the faults, such as the internal wood of these thermosetting resins, by mixing a complete soap and thermosetting resins, such as urea-formalin and melamine-formalin. In the paper industry, coating PVA aqueous solution on the surface of the paper improves the surface properties of the paper, such as smoothness, wear resistance, oil resistance, breathability and printability. It is used instead of the conventional starch as an adhesive agent for paper. Fully soapy film is insoluble in water and oil-resistant, so it is used for packaging plants and oils and fats. It is used for packing textiles and fibers using moisture permeability and strength, and partially saponified PVA film is used for packing detergents, pesticides and dyes using water solubility.

In the case of civil engineering works that are being implemented in Korea recently, depending on the purpose of the construction and the conditions of the budget, it is not uncommon to take the situation that creates a law rather than construct a road along the contour line and straighten it. Is rising.

If the incision consists of soil such as ocher, martha, and amber mixed soil, it may cause decay and earthquake accidents due to rainfall and weathering due to rainfall, as well as unsightly appearance, and the incision becomes weathered rock, In the case of rocks such as limestone, there is a fear of falling due to impact cracking and falling rocks due to the cracking caused by the explosives such as explosives and the vibration of the breca work during the cutting process.

In the case of these laws, most of them have very unfavorable conditions for the vegetation to grow on the ground condition or soil shape, so it is expected that the grassland will be spontaneously formed early or the trees will grow and grow firmly on the ground and grow into a green forest like the surroundings. Because it is difficult to expect in reality, in the case of the soil surface caused by cut or fill, these plantings are sprayed with vegetation made of artificial soil mixed with vegetation seeds, or cracks are generated and adhesion is unstable. In the case of rock incisions that have the same vegetation, artificial greening is performed by striking the rock incision surface and anchoring them to prepare for loss of vegetation, and then installing vegetation made of artificial soil mixed with vegetation seeds on the web. Is generalized.

However, the above-mentioned method tends to have more cracks due to the severe cold weather, and the evaporation of moisture tends to be more severe, and when the drought continues for a long time, the germinated seeds are rapidly evaporated to dryness in the thinly constructed part. There was a problem that led to this death.

Therefore, the central problem solving method of legal greening is water supply. Solar heat and carbon dioxide in the air, which are the growth conditions of plants, are endless, but the water supply is not easy in the special situation of the steep slope, and the technology for attaching soil and fertilizer suitable for plant growth on the slope is being developed.

In addition, cement flocculant is used as soil shortening agent to prevent the loss of materials or steep slopes, and it includes local mixed species and agricultural water.

Vegetation restoration uses various types of plants. Commonly used grass species and various herbaceous and woody species are used depending on the nature of the soil to be restored. The above-mentioned plants for restoration are used by themselves as having excellent growth ability, but in general, the target soils to be restored are often in a poor environment, so they are intensively managed after restoration, especially from the construction stage for rapid settlement of plants. Concentrate on greening, soil stabilizers and blended fertilizers.

The present invention is added to the super-absorbent polymer PVA semi-permanently exerts the effect of moisture absorption on the cotton recording material that acts as described above to delay the evaporation of water and to deliver the moisture to the seed plants effective in the soil that plants can absorb Significantly increases moisture and makes adhesion to the mounting surface easier. According to the addition of the polymer PVA, PVA is mixed in the soil and evenly spread and mixed, so that water is kept for a long time and supplied to plant seeds for the germination and growth of the initial plant.

In addition, the front recording material using the polymer PVA has the effect of the adhesion and when the PVA is sprayed to the mounting place is adhered to the surface without voids and prevent the seed of the plant from being lost by the rain or the like.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to Table 1.

The green grass using the superabsorbent polymer PVA is mainly composed of greening base material, curing material, soil granulator (flocculant) and local mixed herb species, which are plant seeds, mixed by using agricultural water, and high moisture absorption and moisturizing power as soil stabilizer. It comprises the absorbent polymer PVA.

The greening base is composed of a mixture of 20% by weight of Masato, 10% by weight of clay, 20% by weight of organic fertilizer, and 15% by weight of vermiculite when the total weight of greening material and cured material is 100%. Masato and viscous soils, which are used as direct growing loams, should use local soil as a general rule, and the amount of masato and viscous soils may be 30 to 50% by weight. Masatos are grains formed by erosion of stones or wear rings, and viscous soils are aggregated soils of 0.002 mm or less. If clay soil is inadequate, clay or sand is added and used in proportion, which is economical and has self-adhesion, and helps germination and growth of plants.

In addition, the organic fertilizer is a product fermented with at least six months of pig flour or manure, so that the organic matter is maintained for a long time to improve the later growth of the plant. Compound fertilizers contribute to the stable growth of plants by adding mineral fertilizers lacking organic matter.

In addition, the vermiculite is a porous and absorbing mica, especially a modified product of biotite, which is a material of silicate minerals that is mined as a silicate mineral, which is light and inexpensive, and can retain moisture more than 10 times its own weight. You can replenish your plant with the amount you need at any time.

Sterilized by autoclave sterilization and rich in natural organic fiber, it has excellent moisturizing preservation power and excellent breathability, which makes root growth vigorous, promotes the growth of microorganisms, and decreases the temperature change during the winter season. prevent.

In addition, the coco peat is a completely pollution-free organic organic component extracted from the part of the natural coconut fruit peeled from the fiber part, lignin and cellulose components are used a lot for horticulture for soil, easy to use and many Contains nutrients, making it an excellent base material. It is a material with no environmental pollution, and has excellent root growth due to its breathability, water-retaining ability, and low-binding ability. In addition, it is composed of neutralizing substances that change the soil to dark brown or black to increase the absorption of solar heat and fix the soil between acidity 5.5 ~ 6.5.It promotes the activity of microorganisms in the soil, causing useful chemical reactions to the soil, and does not decay for a long time. Improve physical properties

In addition, the sawdust helps to increase the respiration of the plant root system in the soil and to maintain proper moisture in the soil, to promote fertilizer effect and indigenous microbial activity in the soil, and to prevent soil acidification and loss of soil.

In addition, the chemical fertilizers are used in combination in an appropriate ratio with a fertilizer prepared by applying a chemical method to the inorganic raw material.

The soil granules are used when spraying the cotton greenwood according to the present invention. The soil granulating agent is a cement coagulant, 10 to 80% by weight of cement cement, 20 to 85% by weight of tung rock, 1 to 10% by weight zeolite, 1 to 10% by weight of diatomaceous earth, 1 to 20% by weight of gypsum plaster Use it. Fixing cement is more absorbent than general cement and has good porosity and strength retention. Hydration reaction with weathered soil, gypsum, zeolite, and diatomite of tuff facilitates contact and solidification. Weathered soil of tuff is easy to purchase and is suitable for reducing the hydration heat of cement and improving fluidity. Diatomaceous earth reacts with water to promote aggregation. Hemihydrate gypsum dissolves in water and dissociates and aggregates with the weathered soil component of tuff to form calcium hydrate.

A super absorbent polymer PVA is used as a soil stabilizer in addition to the greening base materials, curing materials, and soil granules. PVA inputs 1kg per 1㎥ of water mixed with greening base material, curing material and native mixed species. At this time, PVA is used by dissolving powdered PVA in water.

The PVA is a water-soluble resin obtained by adding caustic to a methanol solution of vinyl polyacetate with a chemical formula (CH2CHOH) n and gelling it in the form of a white granule or powder. Some of the acetic acid groups of vinyl acetate as raw materials are left unreacted and soluble in organic solvents, and insoluble in water. Some residues of acetic acid are easily dissolved in water, making it an aqueous solution and used as an adhesive or emulsifier. In addition, it is very stable and can be stored semi-permanently in a place without moisture.

In addition, the superabsorbent polymer PVA is excellent in absorbency to supply moisture necessary for plant growth, including moisture for a long time, and when the water evaporates with time, it turns to solid again. It maintains proper moisture in the soil and supplies water through the roots of plants.

In addition, because of the adhesive property, when the composition of the greening material solidifies on the surface, it gives adhesiveness so that the surface of the greening material and the curing material are adhered to each other. Enables you to play a role.

The native mixed vegetation species, which are not explained, are the basis for the greening of the legal surface and are commonly used grass species, which use 25g per 1m2 of greening composition. At this time, the native mixed herb species is used various herbaceous and woody according to the properties of the soil to be restored.
And agricultural water is used for mixing the above materials. Agricultural water (water) uses 500 liters per 1,000 kg of the total weight of the greening base material and the curing material. The amount of water may vary slightly depending on the condition of the greening base and the hardwood.
