The present invention relates to a cover for weed prevention, in the cover for weed prevention for use to cover the ground of the planted crop area, crop seating hole is formed in the central region and the lower passage connecting the crop seating hole and the peripheral edge A lower cover plate portion having an incision line formed therein and a lower passage hole formed therein, and coupled to the lower cover plate portion disposed on an upper side of the lower cover plate portion and supported by the lower cover plate portion and circumferentially at an outer end of the lower passage cut line. An incision connecting line is formed along the direction, and an upper through cut line for connecting the end of the incision connecting line and the crop seating hole is formed, and an upper cover plate portion having an upper through hole formed so that sunlight does not reach the lower through hole. A cover body of opaque material having； The lower flange of the closed loop shape is formed extending from the cover body toward the center of the crop seating hole and a lower extension cut line is formed from the circumferential edge toward the inner circumferential surface of the crop seating hole and the upper side of the lower flange. It is characterized in that it comprises an opaque cover support portion having an upper flange formed extending from the cover body and having an upper extension cut line formed so as to be disposed between the area between the lower extension cut line. Thereby, sunlight can be prevented from reaching the circumferential region of the crop, the crop seating hole can be enlarged by adapting to the growing crop, and water can be well supplied to the circumferential region of the crop.본 고안은 잡초방지용 덮개에 관한 것으로서, 식재된 작물의 둘레영역 지면을 덮는 데 사용하기 위한 잡초방지용 덮개에 있어서, 중앙영역에 작물안착공이 형성되어 있고 상기 작물안착공과 둘레연부를 연결하는 하부통과절개선이 형성되어 있으며 하부통수공이 형성되어 있는 하부덮개판부와, 상기 하부덮개판부의 상측에 배치되고 상기 하부덮개판부에 지지되도록 상기 하부덮개판부에 결합되고 상기 하부통과절개선의 외측 종단에서 둘레방향을 따라 절개연결선이 형성되어 있으며 상기 절개연
