FIELD: agriculture.
SUBSTANCE: invention relates to the reclamation of unproductive saline lands. The method includes surveys, including soil agromeliorative surveys of the site, with the diagnosis of aerial photographs and echo testing of indicators of the state of degraded lands and the development of design routes of irrigation and flushing channels and anti-erosion walls on the lee-side of the channels. A program is prepared for switching on and off the working bodies from the control panel and transmitting the results to the control processor of a combined self-propelled unit that performs sequentially simultaneous two-tier processing of a strip of saline soil. The construction of an irrigation and flushing channel is carried out during excavation of soil with one-sided dumping to the anti-erosion wall, sowing seeds of tall-crop samples and halophytes that eliminate salinity, targeted application of the ameliorant, strip dumping of organo-mineral fertilizer layer. The method includes loosening, pruning of a highly saline layer of soil for its clamping, simultaneous horizontal movement of the cover layer to the roller farthest on one side from the longitudinal axis of movement, and the undercover slightly saline layer is moved wedge-shaped on two sides to the near rollers. The combined unit includes a self-propelled basic chassis with a three-section frame with two traction wheel pairs mounted on each section of the frame with reinforced rubber-metal tracks with a triangular wheel outline. A cabin is installed on the first section of the frame. A front manipulator with a swing beam is located before the cab with a movable mounting of five frames with three-row disk headers. The front manipulator, located on the second section of the frame, contains a rotary channel digger with a mechanism for one-way pneumatic injection of cut soil, on the third section of the frame there are: a compressor, a product pipeline, dispensers for seeds, a container for a solution of nitrogen-fixing microorganisms, a device with a monitor for hydraulic sowing to cover the created organo-mineral fertilizer layer-bed.
EFFECT: invention provides for the restoration of degraded saline lands and the creation of saline soil with vegetation on reclaimed agricultural lands that reduces the risk of wind erosion.
