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.
