The present invention relates to a method for coating seeds having a wax layer on the surface thereof, and coated seeds manufactured thereby. According to the present invention, the method may improve a seedling establishment ratio and realize manpower reduction through the prevention of damage by birds. Moreover, the method provides an advantageous effect that the seeds are prevented from moving by various external causes due to the increased weight of seeds, and that growth of crops is promoted, so the method can be usefully applied to seed coating of smooth crops, such as soybean, having a wax layer. According to the present invention, the method comprises the following steps: removing foreign materials from soybean seeds coating a bird repellant including a surfactant to the soybean seeds mixing iron components and plaster with the coated soybean seeds and drying the soybean seeds.COPYRIGHT KIPO 2016본 발명은 표면에 왁스층을 갖는 종자의 코팅 종자 제조방법 및 상기 방법에 의해 제조된 코팅 종자에 관한 것으로, 본 발명에 의한 코팅 종자 제조방법은 조류피해 예방을 통한 입모율 향상과 노동력 절감 효과를 기대할 수 있고, 종자를 무겁게하여 다양한 외부 원인에 의해 종자가 이동되는 것을 방지해주는 효과가 있고, 작물의 생장을 촉진하는 효과 등이 있어, 콩과 같은 매끄럽고 왁스층을 가진 작물의 종자 코팅에 유용하게 이용될 수 있을 것이다.
