The present invention relates to a direct seeder comprising: a main body including one side connected to a rear portion of a vehicle to move together with the vehicle when the vehicle moves; a rotary unit installed on one side of the main body to rotate, including one side connected to a power source of the vehicle, and rotating by the power of the vehicle to plow a cultivation plot and transmit a part of dug soil to the rear; a polyethylene film supply unit installed at the rear of the rotary unit on one side of the main body to freely rotate, including an outer side wound by a polyethylene film with one side fixed to the cultivation plot, and supplying the polyethylene film to an upper portion of the cultivation plot while moving together with the main body when the main body moves; a culturing soil supply unit installed above the vinyl supply unit on one side of the main body, transferring the soil transmitted from the rotary unit by a predetermined distance, and falling the soil on an upper portion of the polyethylene film supplied to the cultivation plot; and a sowing unit including a self-power part which is installed at the rear of the culturing soil supply unit on one side of the main body to freely rotate and is supported on the cultivation plot, and a seeding unit which is connected to the self-power unit to receive the power, is eccentrically coupled to a rotary shaft, and sows seeds supplied from the outside while moving in a vertical direction. According to the present invention, moving force of the main body is converted into driving force, and a harrow unit, the culturing soil supply unit, the polyethylene film supply unit and the sowing unit are driven by the driving force such that an increase in the volume of the present invention can be minimized. In addition, operations required for a sowing operation from a plow operation to a polyethylene film supply operation and a sowing operation can be uniformly performed and thus, manpower and time require
