Living garbage saline-alkali soil conditioner for greening planting

Abstract

The invention discloses a living garbage saline-alkali soil conditioner for greening planting. The main points of the technical scheme of the present invention are as follows: ingredients are composedof living-garbage compressed nutrition soil, living-garbage carbonized soil, acidified attapulgite clay particles, acidified straw, desulfurized gypsum, humic acid, a powdered saline-alkali soil water-retaining slow-release fertilizer, attapulgite clay, ferrous sulfate and water. After the ingredients are stirred and mixed uniformly, the mixture is packaged into the living garbage saline-alkali soil conditioner for greening planting. Calcium and magnesium ions contained in the soil conditioner can replace sodium ions in colloid of saline-alkali soil, so that the exchangeable sodium content inthe soil is decreased, the degree of alkalinity of the soil is reduced, and also the fertility of the saline-alkali soil can be significantly improved, the content of organic matter, calcium, magnesium, silicon, sulfur, nitrogen, phosphorus and potassium in the saline-alkali soil is increased, so that the purpose of improving saline-alkali soil is achieved, the survival rate of greening plantingis improved. The living garbage saline-alkali soil conditioner for greening planting is suitable for improving saline-alkali soil and greening planting in saline-alkali soil.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to a soil conditioner for greening and planting trees in saline-alkali land of domestic garbage. 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...

AI Technical Summary

Problems solved by technology

[0009] 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

[0011] 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 a low-toxic hazardous chemical, but the sulfur dioxide produced by its steam and sulfur combustion is highly toxic to the human body, so it is not suitable for saline-alkali soil conditioners

(2) Although "bentonite" is selected in the ingredients, those skilled in the art know that the pH value of sodium-based bentonite is generally 8.5-10.2, and that of calcium-based bentonite is generally 6.9-8.5. "Bentonite" is an alkaline soil. Therefore, "bentonite" has not been acidified and modified, and it is not suitable for soil conditioners in saline-alkali land
