The invention relates to a special disc type single-side ditcher for lycium chinense. The special disc type single-side ditcher for the lycium chinense comprises a frame body, a power transmission device, a depth-limiting wheel and a disc type ditching device, wherein the power transmission device is assembled on the frame body, the depth-limiting wheel is assembled at one side of the frame body,the disc type ditching device is assembled at the other side of the frame body, a power input end of the power transmission device is connected with a power output end of a tractor, and a power outputend of the power transmission device is assembled with the disc type ditching device. The special disc type single-side ditcher for the lycium chinense has the advantages that the disc type ditchingoperation of the lycium chinense can be achieved; the rear end of the tractor is connected with the front end of the frame body, the power output end of the tractor is connected with the power input end of the power transmission device, and the height of the depth-limiting wheel is controlled, so that the depth of ditching can be adjusted; the tractor transmits power to the power transmission device, the power transmission device transmits the power to the disc type ditching device, and the disc type ditching device rotates for ditching; the energy source output is saved, and the ditching efficiency for lycium chinense planting and fertilization is improved.
