FIELD: agriculture.
SUBSTANCE: method includes the excavation-free diagnostics during the survey, the mapping of the site, the preparation of the programme for switching on and off the operating elements from the control panel and linking the coordinate system via the GPS receiver of the combined unit with the reference to the geographical coordinates, and transmitting the results to the control processor of the combined unit performing the simultaneous processing. Shrub growth, stems of herbaceous plants and soil aggregates are mechanically ground with separating into fractions, bulk subsoil loosening is carried out. The soil is chemically treated with distributing an ameliorant and mineral fertilizers, liquid manure and a solution with nitrogen-fixing micro-organisms are introduced in the soil, seed mixtures are additionally sown at strip cultivation of plants, seed mixtures of legumes and an integumentary grain crop are sown over the screen, and on the marker strip - seed mixtures of drought-tolerant halophytes, treated with growth stimulants. Bulk subsoil loosening is carried out with the formation of a curved surface of the loosened soil bottom for draining the products of chemical reactions with water from the soil to the strip with halophytes without being carried to rivers and water bodies. Screens waterproof during the period of atmospheric precipitation and permeable by the roots of plants during drought are formed, the organomineral mixture in the gas shell is supplied to the screens through the cavities of the racks of voluminous rippers under dumps, with its composition, vol. %: 35…50 - plant residues and humus, 3…10 - montmorillonite, 15…40 - marine mixed sediment type, 0…15 - iron vitriol, 15…37 - clay. Wherein the main treatment of strips with dump-free depth-adjustable cutting of the upper soil layer is carried out and simultaneously the underlying layer of soil and subsoil solonetz is treated. The chemical ameliorant is applied to disintegrated lumps, an interlayer of 0.03…0.08 m from liquid manure is formed in a cavity between the cut-up soil layer and that treated with introducing an ameliorant.
EFFECT: shortening the terms of reclamation works and favourable air and nutrient regime for the development of the root mass of plants and increasing their yields allows to reduce labour costs for pre-design studies, to obtain on rainfed lands desalinated soil with a moisture reserve while regulating the volumes of water accumulated above the screens and in the loosened ground, contributes to the implementation of works with directed treatment of hummocks, curtains of bushes, solonetz with savings of introduced ameliorants, prevents the development of wind erosion.
