Abstract

The invention discloses an ecological integrated improved facility and improving method for saline and alkaline land. The ecological integrated improved facility and improving method are characterized in that: according to the ecological integrated improved facility for the saline and alkaline land, a salt removing filter layer is filled in a blind ditch; a layer of non-woven fabric is paved on the surface of the salt removing filter layer; mixed soil a of original soil and organic matters is filled above the non-woven fabric of the blind ditch; the blind ditch is filled and leveled up with the mixed soil; small square plots are arranged above the mixed soil a; acid salt removing columns are equidistantly arranged on each work plot; plants are respectively planted on each work plot; and thick peat soil is paved on the surface of the soil around the plants. The ecological integrated improving method for the saline and alkaline land comprises the following steps of: blocking; arranging the blind ditch; filling the blind ditch; filling and leveling up the peat soil; applying the organic matters; washing and removing salt; applying a modifying agent and acid fertilizer to the saline and alkaline land; arranging the salt removing columns; deeply ploughing and cultivating; and paving the thick peat soil. The ecological integrated improved facility and improving method disclosed by the invention have the advantages that a soil crumb structure is helped to form; the water permeability performance among soil layers is improved; and the development of crop root systems is effectively promoted.
