Calcium and magnesium ions contained in the soil conditioner can replace sodium ions on a saline-alkali soil colloid, so that the content of exchangeable sodium ions in soil is lowered, and soil alkalinity is reduced; meanwhile, the fertility of the saline-alkali soil also can be obviously improved, the contents of organic matters, calcium, magnesium, silicon, sulfur,nitrogen, phosphorus and potassium in the saline-alkali soil are increased, the aim of improving the saline-alkali soil is achieved, green tree planting survival rate is increased, and the sepiolite tailing saline-alkali soil green tree-planting soil conditioner is applicable to improvement of the saline-alkali soil and green tree planting on the saline-alkali soil.

InactiveCN105969382AImprove organic levelImprove physical and chemical propertiesOther chemical processesOrganic fertilisersPeatIron(III) sulfate
The invention discloses a remediation agent for improving soda-alkalized soil. The remediation agent is made from the following raw materials, by weight part, 25-27 of straw ash, 7-9 of peat powder, 1.7-2.0 of calcium nitrate, 6-7 of powdery flue-cured tobaccos, 2-3 of tourmalinite powder, 2.4-2.6 of sargassum thunbergii powder, 1.6-1.8 of polyferric sulfate, 74-76 of polluted pig dung and urine, 16-18 of a black liquor from papermaking, 4-5 of a nitric acid solution with the concentration being 10%, 14-15 of a thick alum liquid and a proper amount of water. According to characteristics of the soda-alkalized soil, the remediation agent contains multiple soluble components which can generate a large amount of cations through hydrolyzation during usage, and the cations can replace exchangeable sodium in the soil. Since the organic matters are good in adsorption and a polyhydroxyl complex is generated, colloid particles in the soil can be aggregated, thereby improving the physical and chemical properties of the soil, reducing the PH value of the soil, and improving the acid-base slow-release property of the soil. Therefore, the use value of the soil is increased.

Soil conditioner for greening tree planting in illite tailing saline-alkali soil
The invention disclose a soil conditioner for greening tree planting in illite tailing saline-alkali soil. The key point of the technical scheme is that in that the ingredients consist of illite tailing compressed nutrient soil, illite tailing carbonized soil, acidified zeolite particles, acidified straws, desulfurized gypsum, humic acid, a powdery saline-alkali soil water-retaining slow-release fertilizer, attapulgite clay, ferrous sulfate and water; the ingredients are mixed uniformly by stirring, and then the mixture is packaged to obtain the soil conditioner for greening tree planting in the illite tailing saline-alkali soil. Calcium and magnesium ions contained in the soil conditioner can replace sodium ions on saline-alkali soil colloid, so that the content of exchangeable sodium ions in the soil is reduced, the alkalization degree of the soil is reduced, the fertility of the saline-alkali soil can be obviously improved at the same time, the content of organic matters, calcium, magnesium, silicon, sulfur, nitrogen, phosphorus and potassium in the saline-alkali soil is increased, the purpose of improving the saline-alkali soil is achieved, and the survival rate of greening tree planting is improved; the soil conditioner for greening and tree planting in the illite tailing saline-alkali soil is suitable for improvement of the saline-alkali soil and greening tree planting inthe saline-alkali soil.
