FIELD: agriculture.SUBSTANCE: method comprises cutting furrows, layout of tubers and embedding of them in the soil. The soil is loosened and separated into two streams on mouldboard wings. Then each stream is repeatedly loosened and the soil is separated into two streams with windows formed on the mouldboard wings, the width of which is regulated by valves. The tubers are embedded depending on the temperature regime of the soil air-permeable soil layer with the thickness of 1-2 cm. The opener comprises a rack having a breast at the lower part, left and right mouldboard wings tuber-duct. The tuber-duct is mounted at the upper part of the wings. The windows are made on the mouldboard wings. In the windows with the ability to adjust their width the L-shaped valves are mounted. The windows are placed at one-third from the rear part of the mouldboard wings. The valves are mounted from the rear part of the wings and provided with long and short sides located at an angle 120°. The valves with their short side are hingedly connected to the front part of the wings, and the vertical openings are made on the other end of the valve. Above the openings the guides are placed, which with their upper part are rigidly attached to the wings. At the lower part of each guide a threaded opening is made. In the threaded opening a regulating bolt with a conical end is mounted. At the free end of the long side of each valve a regulating handle is made.EFFECT: technology and design enables to increase the yield of potatoes due to reducing the temperature drop in the tubers and their stolons.2 cl, 3 dwgСпособ включает нарезку борозд, раскладку клубней и заделку их почвой. Почву рыхлят и разделяют на два потока на крыльях отвалов. Затем каждый поток повторно рыхлят и разделяют почву на два потока выполненными на крыльях отвалов окнами, ширина которых регулируется заслонками. Клубни заделывают в зависимости от температурного режима почвы воздухо-водопроницаемым слоем почвы толщиной 1-2 см. Сош
