In the present invention, by using the coffee extract and the cacao extract without using such iron powder and calcined gypsum, germinability can be increased as compared with the conventional art.

Hereinafter, each component will be described in more detail.

Anthraquinone ( Anthraquinone )

Anthraquinone is an aromatic organic compound, an anthracene derivative. It is a pale ashy-toned chemical from yellow. In addition, it is a substance that has no avirulance to algae, and is a component of avian avoidance effect, which is known as intestinal irritant after ingestion which causes rejection in the intestine when contacted or ingested, rather than triple neurotrophic stimulant.

In particular, anthraquinones are found in the roots of Rumex, the roots of Rheum, the roots of Ligusticum, the fruit of Cassia, Achyranthes bidentata, Ardisia japonica, , Astertataricus, Eupatorium spp, Aloe spp, Polygonum spp, Evodia officinalis, Hemerocallis fulva, Inula helenium, Mentha spp. a hexane fraction of plants selected from the group consisting of haplocalyx, Paulownia coreana, Petasites japonicus, Rhamnus davurica, Rhamnus crenata, chicory, chrysanthemum and mixtures thereof, and ethyl acetate Lt; / RTI >

In the present invention, anthraquinone is preferably used in an amount of 1 to 5% by weight in the total weight of the seed coat, and when it is used in an amount of 5% by weight or more, the cost is very high, , The content of anthraquinone is too small to anticipate the anthraquinone avian avoidance effect.

Coffee extract

Coffee extracts are absorbed by the body in various forms and include caffeine, which acts on the central nervous system to awaken the mind and reduce fatigue. This can lead to poisoning if taken over a long period of time.

The coffee extract can be obtained by using coffee beans as a raw material and solvent extraction using a solvent such as water, alcohols or ethyl acetate.

If the amount of the coffee extract is too small, the seed germination rate and growth and algae avoidance effect are not exhibited. If the amount of the coffee extract is too much, the content of other active ingredients is small So that it may rather deteriorate the avian avoidance effect or decrease the adhesion with the seed.

In the present invention, the coffee extract was used as a component capable of obtaining germination rate increasing effect and algae avoiding effect at the same time.

Cacao (cocoa) extract

Cacao is produced in the tropics. The seeds contain about 2% of theobromine, some caffeine, and 50% fat. In the ripe fruit seeds, a unique scent is produced, which is called cacao bean.

The cacao extract can be obtained by extracting cacao beans with a solvent such as water or alcohols, and then volatilizing the solvent to obtain a cacao extract.

If the amount of the cacao extract is too small, there is no germination rate, growth and avian flapping effect. If the amount of the cacao extract is too much, the content of the other active ingredients becomes small. Rather, it may lower the avian avoidance effect and decrease the adhesion with seeds.

Essential oil component

 It is preferable that the essential oil component (or bird repellent component) of the present invention is a liquid (particularly, an essential oil) or a powder. Examples of the essential component include peppermint extract, cinnamon extract, methylanthranilate, lemon grass, , Capsaicin, early pinecoptera extract, and pine extract. In addition to the above components, the essential oil component of the present invention may contain ingredients known to have avian repelling effects.

According to the present invention, it is possible to prevent the damage caused by ingesting seeds that have been sown by algae because of the avian repellent agent, and since the algae do not approach seeds, the transfer of sicknesses to the seeds can be prevented,

In the present invention, the essential oil component in the total weight of the seed coating agent is preferably 1 to 5% by weight. If the amount is too small, the bird's repelling effect can not be expected. If the added amount is too large, the other effective materials previously used can not be effective. Therefore, the above content range is preferable.

adhesive

In the present invention, the pressure-sensitive adhesive is used as an adhesive for allowing the mixture to be coated on the seed well. For example, Arabic gum is preferable as an additive for increasing tackiness and viscosity, enhancing emulsion stability, and improving physical properties and tactility. In addition to the gum arabic, an adhesive such as xanthan gum, carboxymethylcellulose A pressure sensitive adhesive for industrial use such as a pressure sensitive adhesive for foods and sodium alginate, an acrylic pressure sensitive adhesive, a terpene based resin, a xylene resin, a silicone pressure sensitive adhesive, a rubber pressure sensitive adhesive, an epoxy pressure sensitive adhesive, a conductive pressure sensitive adhesive, a UV curable pressure sensitive adhesive and a heat peeling pressure sensitive adhesive Can be used. Considering environment friendliness, it is preferable to use food grade adhesive rather than industrial adhesive.

In the present invention, 5 to 10% by weight of a pressure-sensitive adhesive is preferred in the total weight of the coating agent. If the content of the adhesive is too small, there is no adhesion effect. If the content of the adhesive is too large, the content of the avian repellent material becomes too small to reduce the coating effect, so the above range is preferable.

water

The water is mixed in the last step of the above-mentioned algae avoiding mixture. It is preferable that the water is thoroughly mixed in order to completely dissolve the algae avoiding material to prepare a coating solution and used for seed coating.

In the present invention, water is preferably 72 to 92.4% by weight in the total weight of the coating agent, but since water evaporates after coating, the content of the coating agent can be relatively freely increased or decreased as compared with other components. If the use of water is too much, the coating liquid will be diluted in a liquid state and the coating liquid will flow without being coated on the seed. On the other hand, if the use amount of water is too small, the coating liquid becomes a solid state, The coating can not be performed.

Additional ingredient

In the present invention, one or more of chitosan, corrosion acid, sodium alginate, starch powder and the like may be optionally used, but the present invention is not limited thereto. These additional ingredients can increase the binding and adhesion of the seeds more firmly when coating the seed surface, and can enhance bioactivity and improve the soil improvement effect. It is possible to control the proportion of the coating material such as increasing or decreasing the ratio of any one or more of the above-mentioned materials in consideration of the type of seed, cost, convenience, efficiency, etc. For example, 0.1 to 5% by weight.

Hereinafter, the effects of the present invention will be described with reference to Examples and Experimental Examples.

[ Example ]

In the present invention, arabic gum was uniformly mixed with anthraquinone, a coffee extract, a cacao extract, an essential oil component, and a peppermint extract and a pressure-sensitive adhesive. At this time, the content of each component was 3 wt% of anthraquinone, 3 wt% of coffee extract, 1 wt% of cacao extract, 3 wt% of essential oil components, 5 wt% of chitosan as an additional ingredient, 7 wt% of a pressure- Respectively.

[ Experimental Example  One] Foot massage  And germination rate experiment

The germination and germination rate of the untreated seed (soybean) without the seed coating as the coating agent of the above example and the comparative example were tested.

The experimental sites were tested in two places: a plate incubator and soil.

Particularly, in Experimental Example 1, the effect of increasing the germination rate was tested using the seed coating agent of the present invention containing a coffee extract and a cacao extract.

Test Type Test Items Test period Untreated group (%) Coated group (%) plate Foot massage Four days 90 100 Germination rate Seven days 95 100 soil Foot massage Four days 87 100 Germination rate Seven days 94 100

In this experiment, the germinating energy indicates the number of seeds germinated within a week after the germination test, and the germinal size indicates the germination strength of the seed. Percentage of germination refers to the percentage of seeds germinated within a few days of the germination survey, assuming germination of seeds bearing normal rootstocks and infants.

In the plate incubator experiment, the germination and germination rates of the untreated group were 90 and 95%, respectively. When the seed coat of the present invention was treated, the germination and germination rates were all 100%.

On the other hand, in the soil test, the germination and germination rates of the untreated group were 87 and 94%, respectively, and the germination and germination rates were all 100% when the seed coating composition of the present invention was treated. It was confirmed that the seeds germinated at the time of germination can be pulled when the coffee extract and cacao extract are contained, and that the consistent germination ratio and root thickness are strong and the germinated seed is constantly grown without warping. It is predicted that the components contained in coffee extract and cacao extract are closely related to the growth of seed.

[ Experimental Example  2] Cage  Experiment of Avoidance of Avian Within

 Experiments were conducted on the effect of avoidance of algae on crosses. The seeds coated with the coating agent of the present invention and the untreated seeds not treated with the coating agent were placed in equal amounts in each of the cross drums, and the amount of the remaining seeds was measured after one day. Experiments were repeated two times in total.

The experimental results are shown in Table 2 below.

One-time experiment
(Moi Yang, g) Two-time experiment
(Moi Yang, g) effect(%) No treatment 0h 12.16 12.01 - 9h 7.57 6.62 59 24h 5.94 3.15 38 48h 4.15 2.85 29 72h 1.15 0.52 7 Coating treatment 0h 14.83 15.14 - 9h 13.93 14.68 95 24h 13.85 13.52 91 48h 12.60 11.24 80 72h 12.51 11.21 79

Here, in the above table, the effect (%) = (the average of the first and second rounds at 0h) / (the average of the rounds of the first round and the second round after a certain time) * 100.

An important factor in the invention of seed coatings is how well the coating is coated on the seed. If the coating solution is not adhered to the seed well or the seedling is not well coated with the coating solution or takes a long time or peeling off the coating solution at the time of germination, seeding may cause seeding and germination, It can not prevent the damage caused by the damage, and also the loss of time and economy.

In addition, since algae generally damage seeds at the time of sowing seeds, it is necessary that the algae avoiding material (coating liquid) is embedded well until the germination is completed after the seeds are sown and the effect can be continuously exhibited. The seeds treated with the coating agent of the present invention exhibited excellent germination state (germination rate, strength and germination rate) and excellent effect on avian avoidance effect compared to the untreated seeds.
