However, as shown in Figs. 1 and 2, the rice seeds 10 are formed with fine hairs 11 and 12 on the outer circumferential surface and have a weak adhesion to the protective soil 20 due to the rough surface, 3, when the protective soil 20 is broken due to a weak impact or a falling impact upon sowing, the rice seed 10 is exposed to the outside and fed to wild birds or exposed to the outside for a long time, There is a problem in that the function as the "

The present invention has been made to solve the above problems and it is an object of the present invention to improve the adhesion force between a plant seed and a protective soil so that the protective soil is not split or broken by a weak impact or a falling impact upon sending, And which does not lose its function as a seed by drying or the like during prolonged exposure, and a process for producing the same.

In order to accomplish the above object, the present invention provides a method for producing a coated plant seed for direct wave, comprising the steps of spraying water on a plant seed to moisten the plant seed;

Preparing a protective soil comprising loess;

Forming a coating layer by coating the wet soil and the protective soil on a rotating drum and coating the protective soil on the outer surface of the wet plant seed to a desired thickness;

Applying hot air to the plant seeds with the coating layer formed thereon while rotating the rotary drum; And

And 3 to 5 plant seeds in which the coating layer is formed are received in the protective layer and compression molded.

The protective soil is characterized by containing loess, vermiculite powder, silicate powder and an adhesive.

After the compression molding step, at least one of sulfur, iron powder, silicic acid powder, and limestone powder, which the birds do not like, is coated with a coagulant on the outer surface of the protective soak, .

The coating layer may be formed by spraying water onto plant seeds, soaking the protective seeds on the wet seeds, forming a first coating layer thereon, drying the coating layer, spraying water on the first coating layer, Such that the second coating layer is formed on the first coating layer, which is water-repellent, to form a desired coating thickness.

And is characterized by coated plant seeds for direct wave produced through the above-described manufacturing method.

As described above, after the coating layer of the protective seed is formed on the outer surface of the plant seed of the present invention, the protective layer is formed by compression molding to protect 3 to 5 coated plant seeds by protecting soil, The plant seed itself is protected, so that it can be grown as a rice by the coating layer without being damaged as a food by birds or the like.

In addition, since the coating layer coated on the outer surface of plant seeds and the protective soil surrounding the plant seeds are made of the same material, it is possible to integrate during compression molding, thereby further reducing the breakage rate.

Also, even if the surface of the plant seeds has fine hairs and roughness formed on the outer surface thereof, water is sprayed on the plant seeds to wet the protective seeds, and the protective coating is formed on the water to form a first coating layer, And the second coating layer is formed by repetitively coating the second protective coating layer with the protective coating, thereby obtaining a desired coating thickness.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
