Problems solved by technology

[0007] 1) The greater the solubility of the salt, the greater its harm
[0008] 2), the greater the alkalinity, the greater the toxicity
[0009] 3) Different salts have different toxicity
[0010] 4) The toxicity of a single salt is more harmful than that of multiple salts
However, the disadvantage of this improver is the addition of alkaline components such as sodium hydroxide, which is not suitable for the improvement of saline-alkali soil
[0022] In summary, although there are multiple soil improvers in this area, there is still a lack of cheap, fast and effective soil improvers suitable for saline soils.

Abstract

The invention discloses a new-typed salted soil modifier composition and making method, which comprises the following parts: superphosphate, calcium sulfate, poromeric material, decomposed rough organics, phosphogypsum, rough stream and macromolecular (water retention) agent for alkali soil of littoral area.

Description

technical field [0001] The invention relates to the technical field of new materials for forestry. More specifically, the present invention relates to a saline soil amendment composition and its preparation method and use. The saline soil amendment composition contains calcium superphosphate, calcium sulfate, air-permeable materials and decomposed coarse organic matter, and is especially suitable for bioremediation of saline-alkali soil in coastal areas. Background technique [0002] The salinization of coastal saline soil is caused by the salt accumulation process affected by seawater immersion, the salt accumulation process affected by groundwater, surface water, or groundwater and surface water, and the soil salinization process such as the secondary salinization process of soil; and The ecological improvement of coastal saline soil often uses mineralized water as irrigation water source, which brings great difficulties to the development of saline soil improvement.
