Straw salt resistance and amino acid synergistic saline-alkali soil wheat yield increasing method

Abstract

The application discloses a kind of salt-alkali soil wheat yield-increasing method based on deep straw salt resistance and amino acid plant growth regulator synergy, belongs to salt-alkali soil agricultural technology field.For the problem that middle and heavy degree salt-alkali soil spring strong salt return leads to wheat root system damage, single regulator failure, the application proposes the following method: before sowing, ditch is opened at soil depth 3540 cm, fills in 510 cm straw and compacts, constructs physical isolation layer, measures 030 cm plough layer salt reduction 72%, and heavy degree salt-alkali is degraded to light and moderate degree salt-alkali;Wheat is sown and base fertilizer is applied above the isolation layer;Amino acid plant growth regulator aqueous solution is respectively sprayed on leaf in wheat emergence stage, jointing stage, booting stage and full heading stage.The application creates low salt safety zone for root system by physical salt isolation, makes amino acid regulator play resistance and growth promoting role in full effect, and the relative yield of wheat is increased by 46.9% by the synergy of the two, and high yield and stable yield of wheat in salt-alkali soil are realized.
