Method for carrying out raw soil greening on secondary salinized saline and alkaline land by using amino acid salt-containing soil conditioner

Abstract

The invention relates to a method for carrying out raw soil greening on secondary salinized saline and alkaline land by using an amino acid salt-containing soil conditioner. The soil conditioner comprises, by weight, 31-33 parts of fermented pigeon manure, 10-13 parts of decomposed rice straw powder, 3-5 parts of fly ash, 3-5 parts of phosphate rock powder, 2-4 parts of bentonite, 2-4 parts of calcium superphosphate, 1-3 parts of manganese hypophosphite, 1-3 parts of adipic acid, 3-5 parts of amino acid salt, 0.5-0.7 parts of compound sodium nitrophenolate, 0.5-0.7 parts of rapin, 0.5-0.7 parts of a wolfberry fruit extract product, 3-5 parts of sodium silicoaluminate, 0.5-0.7 parts of a starch grafted styrene sulfonic acid copolymer, 1-3 parts of ammoniated superphosphate, 1-3 parts of chelated iron, 1-3 parts of chelated zinc, 0.1-0.3 parts of Bacillus amyloliquefaciens, 0.1-0.3 parts of Bacillus megaterium, 0.1-0.3 parts of Bacillus licheniformis, 0.1-0.3 parts of microzyme, 0.1-0.3 parts of Azotobacter vinelandii and 0.1-0.3 parts of Trichoderma Longibrachiatum.

Description

technical field [0001] The invention relates to a soil improver containing amino acid salts, in particular to a method for greening secondary salinized saline-alkali land with a soil improver containing amino acid salts, and belongs to the technical field of landscaping. Background technique [0002] Secondary salinization is also called "secondary salinization". It refers to the process of soil salinization caused by unreasonable cultivation and irrigation. It mainly occurs in my country's North China Plain, Songliao Plain, Hetao Plain, and Weihe Plain. The main reasons for the formation of secondary salinization: (1) The development of self-flow irrigation, which causes the groundwater table to rise beyond its critical depth, so that the salt rises through the capillary and accumulates on the surface; (2) Using high salinity water for flood irrigation, the salt (3) Reclamation of the subsoil with salt deposits; (4) Due to the frequent tides in the coastal area, a large a...

Problems solved by technology

[0004] (1) Cannot effectively reduce the salt content in secondary salinized saline-alkali land;

[0005] (2) It has no obvious effect on the reduction of chloride in secondary salinized saline-alkali land;

[0006] (3) It has no obvious effect on the reduction of sulfate in secondary salinized saline-alkali land;

[0007] (4) It cannot effectively reduce the pH value of the soil;

[0008] (5) The water holding capacity of the soil is poor, resulting in weak water holding and water holding capacity of the soil
