FIELD: agriculture.SUBSTANCE: method comprises undercutting soil on the contour lines of the slope, its turnover and laying not in their furrows. The layer is undercut in cross section in the form of rectangles of different widths. The two extremes layers are undercut to a depth of (0.7?0.8)h and placed in the furrows formed by ploughing of the middle layers, without turnover, where h is the depth of treatment with double bodies (middle layers). The device comprises a frame, a disc blade, joggers, double body, right- and left-handed plough bodies. The right- and left-handed plough bodies are made with a cylindrical working surface. The plough bodies are mounted on the frame vertically higher than the double body by the magnitude ?h=(0.2?0.3)h, where ?h is the distance between the blades of ploughshares on the vertical.EFFECT: such technology and constructive implementation enable to increase the efficiency of retention of meltwater on sloping lands at optimal costs.5 cl, 6 dwg |
