Zeolite saline-alkaline land afforestation soil conditioner

Abstract

The invention discloses a zeolite soil conditioner for saline-alkali land greening and planting trees. The main point of the technical scheme is that the ingredients are composed of zeolite compressed nutrient soil, zeolite carbonized soil, acidified zeolite particles, acidified straw, desulfurized gypsum, humic acid, powder It is composed of water-retaining slow-release fertilizer for saline-alkali land, attapulgite clay, ferrous sulfate and water; after stirring and mixing the ingredients evenly, it is packaged as a zeolite soil conditioner for greening and planting trees in saline-alkali land. The calcium and magnesium ions contained in the soil conditioner can replace the sodium ions on the saline-alkali soil colloid, reduce the content of soil exchangeable sodium ions, reduce the alkalinity of the soil, and at the same time significantly improve the fertility of the saline-alkali soil. Increase the content of organic matter, calcium, magnesium, silicon, sulfur, nitrogen, phosphorus and potassium in saline-alkali soil to achieve the purpose of improving saline-alkali land and improve the survival rate of greening and planting trees. .

Description

technical field [0001] The invention relates to a soil conditioner, in particular to a zeolite saline-alkali land greening and tree planting soil conditioner. Background technique [0002] Saline-alkali land means that the salt contained in the soil affects the normal growth of crops. Plants in severe saline-alkali soil areas can hardly survive. Soluble salts reduce the ability of plants to absorb water and nutrients, relatively reduce the content of soil organic matter, seriously lack nitrogen, phosphorus, potassium and trace elements, seriously damage the soil aggregate structure, reduce air permeability, and reduce the activity of aerobic microorganisms , slow soil maturation, resulting in soil compaction. Due to salinization, the physical and chemical properties of the soil deteriorate, and the living conditions of plants deteriorate. The work of greening and tree planting in saline-alkali soil is very difficult, and the survival rate of greening and planting trees is o...

Problems solved by technology

[0006] The deficiencies of the above patents are: (1) the "nutrient soil" lacks ingredients for saline-alkali resistance and pH adjustment of saline-alkali land; It can be used in ordinary "original soil greening", but not suitable for "indigenous soil greening in saline-alkali land". In the process of greening and planting trees in saline-alkali land, the survival rate of seedlings is relatively low

[0008] The disadvantages of the above-mentioned patents are: (1) a large amount of sulfur powder (20% to 35%) has been selected in the ingredients. It is...
