The invention relates to a ball-throwing type fracturing slide bushing and a fracturing pipe column. The ball-throwing type fracturing slide bushing comprises an outer pipe and an inner bushing; a first fracturing hole is formed in the outer pipe, and a second fracturing hole is formed in the inner bushing; multiple inner grooves distributed at intervals in the axial direction are constructed on the portions, in the upstream area of the first fracturing hole, of the inner wall of the outer pipe, and a joint hollow level-variable body is formed by the inner wall of the outer pipe and any one of the inner grooves. A ball seat groove is constructed on the portion, located in the downstream area of the inner bushing, of the inner wall of the outer pipe, and an elastic ball seat is arranged in the ball seat groove. According to the ball-throwing type fracturing slide bushing, multiple stages of slide bushings can be opened by tripping balls with the same specification, and therefore the fracturing level is not limited by the size of the tripping balls and the ball seat.
