The utility model belongs to the technical field of the plant cultivation, especially, relate to a bio - organic fertilizer apparatus for producing with prevention and control soil borne disease. Including the fermentation vat, be equipped with the even native device that is located the native device of mixing of lower part and is located upper portion in the fermentation vat, it includes first swinging arms to mix native device, second swinging arms and actuating lever, the one end of first swinging arms is articulated mutually with the fermentation vat inner wall, the one end of second swinging arms is articulated mutually with the fermentation vat inner wall, the other end of first swinging arms is articulated mutually with the actuating lever, the other end of second swinging arms is articulated mutually with the actuating lever, the actuating lever with drive actuating cylinder and be connected, even native device includes anchor post and even native board, the anchor post rotateswith even native board to be connected, the native hole of a plurality of hourglasses has been seted up on the even native board. The advantage lies in: through mixing native device with soil and fertilizer stirring, do benefit to the abundant mixed fermentation of the two, even native device is then even flat with the upper strata, avoids fertilizer accumulative total in a department.
