Description

Spray composition for seed and incision recording method using the same {COMPOSITION FOR SPRAYING SEEDS AND AFFORESTING METHOD FOR ARTIFICIAL SECTIONS}

The present invention is a spray composition for seeds containing water, cellulose fibers and polyethylene oxide resin in a predetermined amount, the seed composition comprising the seeds and the stomach composition, and the stomach seed composition by mounting (spraying) in a predetermined manner to effectively cut the incision surface It is about how to record.

Due to road construction and other reasons, incisions such as mountains and rocks are frequently made. If the soil incision surface or rock incision surface is not rapidly greened, the natural landscape is damaged and various disasters occur due to weather conditions such as rainfall, which is dangerous. Of course, there is a method of approaching such incision only from the point of view of rapid stabilization and finishing it with concrete, but this may destroy the ecosystem and it is difficult to achieve aesthetic harmony with the surrounding environment.

Accordingly, in recent years, a lot of attention and effort has been focused on recording the incision surface by placing importance on the aesthetics, and in particular, by dispersing and dispersing the seeds in an aqueous solution and spraying (installing) the incision surface to recover the incision surface. The way is dominant. However, the method of simply mixing seeds in an aqueous solution is easy to flow due to the low viscosity of the aqueous solution, and there is no centripetal body to hold the seeds, and it is easy to dry, so there is a large amount of unexpected rainfall after seed spraying. Seeds are lost and there is a case in which the rapid loss of moisture during drying may adversely affect the germination of seeds.

Recently, unpredictable rainfalls such as El Niño are frequent, and the ground is often dry because it has not rained for a long time. When seed spraying is carried out by the conventional method, it is more difficult for seeds to take root reliably due to the occurrence of unpredictable weather conditions even if it is effortlessly sprayed on the incision surface.

Therefore, there is an urgent need for the development of effective greening methods and seed spray compositions necessary for minimizing the loss of seeds dried out or washed by water.

It is an object of the present invention to provide a spray composition for seeds that can prevent the seed from being lost by rain or spray after drying, to prevent germination of seeds.

SUMMARY OF THE INVENTION An object of the present invention is to provide a seed spray composition having excellent moisturizing power without falling down even on an inclined surface by including cellulose fiber and polyethylene oxide resin.

It is an object of the present invention to provide a seed composition comprising a spray composition for seeds and seeds for greening incision surface in a specific content ratio.

An object of the present invention to provide a method for recording the incision surface using the seed composition.

The present invention provides the following problem solving means to achieve the above object.

1. A spray composition for seeds comprising 0.1 to 0.5% by weight of cellulose fibers, 0.1 to 0.5% by weight of polyethylene oxide resin and water so that the total weight is 100% by weight.

2. The spray composition for seeds according to the above 1, containing 0.1 to 0.3% by weight of polyethylene oxide resin.

3. Seed composition comprising 60 to 90% by weight of the spray composition of the above 1 and 10 to 40% by weight of seeds for greening incision surface.

4. In the above 3, the incision surface greening seeds are made up of 45-55% by weight tall seed cues, 15-25% by weight perennial seeds, 10-15% by weight creeping seeds and 15-20% by weight of wildflower seeds Seed composition.

5. Incision surface comprising 25-30 g of seeds per unit area (1m × 1m) by spraying the seed composition of the above 3 or 4 to a thickness of less than 1 cm on the incision surface of 2 to 5 cm rust soil How to record.

6. In the above 5, 25 ~ 30g of seeds per unit area (1m × 1m) is 15g tall seed cues, 6g perennial seeds, 4g creeping seeds and 5g of wildflower seeds incision plane recording method.

The spray composition for seeds of the present invention can effectively prevent seeds from being washed away by rain or lost or dried due to drought, and thus, beautifully and stably greening can be achieved within a short time compared to the conventional method.

The spray composition for seeds of the present invention allows the green soil and seeds of the incision surface to be bonded to each other with a strong cohesive strength, strong resistance to washing and to exhibit stable physical properties against cracking. In addition, it has excellent moisture retention, which prevents the seeds from drying out.

The present invention is mixed with seeds in a spray composition consisting of 0.1 to 0.5% by weight of cellulose fibers, 0.1 to 0.5% by weight of polyethylene oxide resin and the remaining amount of water and sprayed to the incision surface with a predetermined thickness, so that the seeds are washed away by rain or lost by drought. The present invention relates to a spray composition for seeds and an incision surface greening method using the same, which can effectively prevent the germination of dry, and thus, beautifully and stably greening in a short time compared to the conventional method.

Hereinafter, the present invention will be described in more detail.

Spray composition for seeds of the present invention comprises 0.1 to 0.5% by weight of cellulose fibers. Cellulose fibers can be used without limitation, those obtained from trees such as pine and fir. Cellulose fibers are mounted on the incision surface three-dimensionally intertwined to form a network structure. This mesh structure prevents seeds and green soil from flowing down.

The cellulose fiber may be preferably used to form a network structure having a length of about 1.5 to 3 mm. When included in the spray composition for seed may be mixed with water together with the polyethylene oxide resin described below, it is more preferable to separately disperse in water to prepare the composition. Cellulose fibers reduce the cracks in the sprayed seed film and green soil, and contain moisture to help seed germination.

The cellulose fiber of the present invention also contributes to increasing the water retention of the seed composition. In particular, the more the number of fibers per 1g of cellulose fibers, the more preferable. For example, the number of fibers is preferably 1.5 million / g or more.

In the composition of the present invention, when the cellulose fiber is less than 0.1% by weight, the inter-fiber binding strength is lowered and the stability is lowered. When the content of the cellulose fiber exceeds 0.5% by weight, inter-fiber entanglement occurs and workability is reduced.

Spray composition for seeds of the present invention comprises 0.1 to 0.5% by weight polyethylene oxide resin. Polyethylene oxide resin can maintain excellent viscosity in water, preventing seed from being washed away by running water.

Polyethylene oxide resins are neutral (pH 7) and water soluble so that they do not adversely affect the germination of seeds, even if they are included with the seeds or on the green soil, increasing moisture retention and increasing viscosity to prevent loss and drying of the seeds.

The polyethylene oxide resin preferably has a viscosity of about 6000 to 9000 cp (1% aqueous solution), but is not particularly limited.

0.1 to 0.5% by weight of polyethylene oxide resin, preferably 0.1 to 0.3% by weight is included. When the polyethylene oxide resin is included in less than 0.1% by weight, the viscosity decreases, so that the loss of seeds due to the flow of water increases, and when contained in excess of 0.5% by weight, the viscosity is too high, the workability is reduced.

The seed is mixed with the spray composition for seeds of the present invention and used by spraying with a sprayer or the like. Incision surface greening seeds are mixed so that the seed spray composition 60 to 90% by weight of the seed containing 10 to 40% by weight.

Seeds for greening incision are usually used for landscaping, greening seeds can be used without limitation, but considering aesthetic viewpoint and stable germination, it is recommended to use a mixture of two or more seeds. For example, seeds comprising 45-55 wt% tolsfew cu seeds, 15-25 wt% perennial seeds, 10-15 wt% creeping seeds, and 15-20 wt% wildflower seeds may be used.

If the incision surface is the same as the cancer incision surface, install about 2 ~ 5 cm of normally used green soil (artificial soil) on it. If soil exists, such as soil cut surface, it may not be installed in some cases, but it is preferable to install the rust soil from the viewpoint of water retention and stability.

For example, the incision surface greening method is possible by spraying the seed composition of the present invention to a thickness of less than 1 cm on the incision surface of 2 to 5 cm, where 25 to 30 g of seeds are installed per unit area (1 m × 1 m). . Applying too much more than 1 cm of the seed composition can be economically wasteful and can entangle cellulosic fibers and resins and reduce workability. In addition, if too many seeds (1m × 1m) per unit area is not suitable for the germination of seeds, if too little is contained the stability of the green area. Therefore, it is desirable to mount 25-30 g of seeds per unit area (1 m × 1 m). For example, it is possible to spray a total of 30 g to include 15 g of tolsque seed, 6 g of perennial seed, 4 g of creeping seed and 5 g of wildflower seed in a unit area.

Example

The spray composition for seeds of the present invention was prepared using commercially available cellulose fibers (trade name: Ultra Fiber 500, source: Chemius Korea) and polyethylene oxide resin (trade name: SPAOX, source: Chemius Korea).

Cellulose fibers were 1.9 to 2.3 mm long, 14 to 17 μm in diameter, 1,590,000 fibers / g (1400 * 10 ⁶ particles / m 3), density 1.10 g / cm 3, and polyethylene oxide resin Grade S-5002, viscosity (1% aqueous solution) 6500 ~ 8500 cp, appearance white powder, specific gravity 1.15 ~ 1.25, apparent specific gravity 0.15 ~ 0.35, pH 6.5 ~ 7.5 was used.

Cellulose fibers were dispersed in water as shown in Figure 1 (0.1% by weight) was used. First, in order to test the water retention performance, a container (Sample 1) in which 0.1 wt% of cellulose fibers was dispersed (a sample 1) and a container containing only water (Sample 2) were kept at about 50 ° C for 8 hours as shown in FIG. After maintaining, the mixture was maintained at room temperature for 12 hours. 50 ℃ was measured at this temperature because the temperature of ordinary soil in direct sunlight in summer is kept above this temperature.

Moisture Retention (%) = {1- (Initial Weight-Post Test Weight) / (Initial Weight)} × 100

The water retention rate of the samples 1 and 2 calculated according to the above equation is shown in the following table, and it was found that the water retention rate was significantly increased by using cellulose fibers. Cellulose fibers can be found that more than 1.5 million fibers per gram intertwined three-dimensionally to improve the water retention performance and to help seed germination with the retained water.

In addition, it was confirmed whether the spray composition for seeds containing polyethyl oxide resin was more resistant to rainfall than the conventional spray composition containing carboxymethyl cellulose (CMC) (using 0.3 wt% of polyethyl oxide resin). ). Polyethyl oxide resin was also first used after dissolving in water.

The seeds were mixed with the prepared spray composition for seed, and then mounted on the specimen, and the specimen was exposed to air for one day and dried (FIGS. 3A and 3B). The water was then sprayed (rainfall) to visually check the condition of the remaining seeds. This test compares losses due to unexpected rainfall after seed spraying or green soil application on the incision surface.

As a result, as shown in Figures 4a and 4b, even when measured with the naked eye it can be seen that the use of polyethylene oxide resin is superior to the flow of moisture than the conventional case.

Finally, after spraying the spray composition for seeds made of the present invention on rust soil as shown in Figure 5 was observed the germination state of the seeds in the air. This test method was conducted in the field with the same conditions as the actual seed spray. The trial took about 15 days and there were three rainfalls during the trial. The atmospheric temperature was about 10 ° C. at 18 ° C. at night. Seeds were used for creeping in this test. The purpose of this test is to determine whether the materials used in the present invention, cellulose fiber and polyethylene oxide resin, affect seed germination.

The germination started 12 days after the start of the experiment, and the germination state was very excellent, so that the cellulose fibers and polyethylene oxide resin used in the present invention increased the moisture retention of the green soil and was excellent in germination of seeds without being washed in the rain. It was confirmed that the influence (Fig. 6).
