FIELD: agriculture.
SUBSTANCE: invention relates to improvement of agricultural lands not used in agricultural production with wavy relief and strong soil acidity, with soil layer from 0.08 m to 0.15 m, on rainfed lands enables to lay organo-mineral biologically active fertilizer mixture (OMBAFM), soil deepening, introduction of ameliorant CaCO3 into slots and pillars between them, zero treatment of soil without its reverse ploughing. Combined meadow unit comprises self-propelled base chassis 2 with three-section frame 3, on each section of frame torsion axles 4 with paired support-traction wheel pairs 5 with caterpillar track 6, and between sections of frame 3 of combined meadow unit is hinged controlled connection 7. In addition, on first section 8 of frame 3 contain cabin 12 with a code receiver GLONASS (CR), an on-board computer (PC), control panel (CP), section mapping unit (SM), control processor (CPr) and behind the cabin contain an internal combustion engine (ICE) with an electronic control unit (ECU) of fuel supply systems, speed control, in front of cabin 12 there is equipment for conversion (CE) of soil state measurement results, subsoiler 21 operation parameters, their digitization with input into PC and ECU, and on first section 8 in front of the CE there is front manipulator 9 of the boom and the frame handle, on which subsoilers 21 are movably fixed, containing ribbed rollers installed in sections of wheel pairs, or one ribbed roller for the entire working width of the unit, auxiliary parabolic vertical knives-slitters, at that, the slot cutters are connected to the wedge-shaped part of the stand, located in front of the stand of the product duct with a nozzle for the introduction of an organo-mineral biologically active fertilizer mixture (OMBAFM), slot-cutter blade arranged between axles of wheel pairs along the longitudinal axis of the unit contains a plate with a built-in measuring unit with measuring sensors. In addition, the unit has a lancet plane cutter on the product pipeline with angle of 5° up to 10° cutting soil, and under it OMBAFM nozzle, at that, the main vertical blade of the subsoiler with an obtuse angle to the movement path in the lower part is connected to the top of the trapezium of the horizontal plane cutter with angle of 15° up to 30° cutting and chipping soil, under it there is a bit with a reamer forming an oval-shaped cavity of water discharge.
EFFECT: invention provides integral supply of the ameliorant, application of OMBAFM components, NPK fertilizers, plant seeds depending on the speed of the unit, the design slope of the bottom of deep tillage and the introduction of calculated discrete doses of CaCO3 are observed, eliminate excessive consumption of the ameliorant, fertilizers, renewal of the existing grass stand.
