Preparation method of salinization soil improving agent

Abstract

The invention discloses a preparation method of a salinization soil improving agent. The method comprises the following steps of fermenting corn stalks; preparing an organic ecological fertilizer; preparing and modifying charcoal; compounding the improving agent. The method has the beneficial effects that the used major raw materials are all from industrial and agricultural production byproducts or wastes; the environment is protected; the comprehensive utilization is realized; the cost is reduced; the improving agent can effectively enhance the organic matter content in the soil; the content of mineral substance elements in the soil solution is increased; the soil fertilizer effect is enhanced; the water holding performance is enhanced; the soil volume weight is reduced; the porosity is increased; the soil structure is improved; through the ion replacement effect of the soil improving agent, the contents of salt base ions such as sodium ions and potassium ions in the soil solution can be effectively reduced; through the rinsing effect, the salt base ions are settled to the soil bottom layer; the harm of the salt base ions is reduced; the pH value of the soil solution can be reduced; the salinization soil is fundamentally improved, so that high economic values and social values are realized.

Description

technical field [0001] The invention relates to the field of soil improvers, in particular to a preparation method of a salinized soil improver. technical background [0002] According to statistics, the area of ​​saline-alkali land in the world has reached 1 billion hm 2 , China is a country with a large area of ​​saline-alkali land, with 34.6 million hm 2 . In China, saline-alkali land is mainly distributed in the northwest inland saline-alkali area, the semi-arid saline-alkali area in the middle reaches of the Yellow River, the arid and semi-arid saline-alkali area in the Huanghuai-Hai Plain, the northeastern semi-humid and semi-arid low-lying saline-alkali area, and the coastal semi-humid saline-alkali area. Under natural conditions, there are two causes of saline-alkali land: primary salinization, that is, the balance between soil groundwater and surface water caused by drought and flood is destroyed, so that the salt of groundwater moves up with the water and eventua...

Problems solved by technology

[0005] The Chinese invention patent of CN 102559197 B discloses a saline-alkali soil improver and a preparation method thereof. The improver is made by mixing amino acids, urea, acetic acid, sodium nitrophenolate and water, and has the advantages of simple process and low cost, but Its component sodium nitrophenolate has the function of revitalizing plant cells, amino acids and urea have the function of increasing nutrition, only acetic acid has a slight alkali neutralization function, so its ability to reduce the pH value of the soil solution is limited, and this amendment does not have the ability to improve soil The function of soil quality cannot reduce the concentration of base ions in the soil solution, so it cannot effectively improve saline-alkali soil from the root, and has no promotion value
