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

Embodiment 1

[0017] 1) Weigh 200 parts of corn straw powder, 100 parts of pond sludge, 75 parts of oyster mushroom edible fungus residue, 15 parts of alcohol residue, adjust the water content to 5-60%, and anaerobically ferment for 15-20 days to obtain fermented corn straw ; convert corn stalks into organic acids, and the pH value of the soil solution can be effectively reduced as the organic acid ammonia content increases; 2) Weigh 45 parts of furfural slag to adjust the pH to 6.3, and then add 100 parts of cow dung, wheat 25 parts of rice stone and 1 part of colloidal bacillus, fermented at 35°C for 18 days to obtain organic ecological fertilizer; organic ecological fertilizer contains a lot of nutrients, and at the same time it can produce organic acids under the decomposition of soil microorganisms; 3) weighing Take 200 parts of fresh sunflower plant powder and place them in a tube-type resistance furnace, and feed nitrogen gas with a flow rate of 300ml / min into the furnace to maintain ...

Embodiment 2

[0019] 1) Weigh 230 parts of corn stalk powder, 120 parts of pond sludge, 80 parts of oyster mushroom edible fungus residue, 25 parts of alcohol residue, adjust the water content to 60%, and pile them in a closed container for anaerobic fermentation for 20 days to obtain fermented corn Straw; fermented corn stalks increase the content of soil organic matter, and organic cations, anions, and soluble substances in corn stalks all have an impact on soil pH;

[0020]2) Weigh 50 parts of furfural slag, adjust the pH to 7.0, then add 120 parts of cow dung, 30 parts of medical stone, and 1.5 parts of Bacillus colioids, and ferment at 38°C for 20 days to obtain an organic ecological fertilizer; organic ecological fertilizer Fertilizer contains a lot of nutrients, and at the same time, it can produce organic acids under the decomposition of soil microorganisms. Combined with the acid solution in furfural slag, it can reduce the pH value of saline-alkali soil. effect, can enhance the nu...

Embodiment 3

[0024] Fermented corn stalks: take corn stalks, wash them, dry them, crush them through a 30-mesh sieve, weigh 220 parts of corn stalk powder, 110 parts of pond sludge, 75 parts of oyster mushroom edible fungus residues, and 20 parts of alcohol residues, and adjust the water content to 55% , piled in a closed container for 18 days of anaerobic fermentation to obtain fermented corn stalks; using sludge as an inoculum, corn stalks can be degraded into xylose under anaerobic conditions, and then converted into organic acids by anaerobic fermentation , as the ammonia content of organic acid increases, the concentration of hydrogen ions in the closed straw fermentation vessel increases, which leads to a gradual decrease in the pH value of the straw. pH value, substitution Na + , while increasing the content of soil organic matter;

[0025] Preparation of organic ecological fertilizer: take 50 parts of furfural slag and add 2.5 parts of ammonium bicarbonate to modify, adjust the pH...

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...
