Problems solved by technology

At present, there are many types of chemical amendments on the market, and the ingredients are relatively single, which has the following disadvantages: first, the cost of the improved materials is high; At the same time, the phenomenon of anti-saline-alkali soil after improvement is serious. Third, there are differences in the salinity categories of saline-alkali soils in the north and south coastal areas. At present, there is no general-purpose composite improver suitable for the saline-alkali areas in the north and south coastal areas of my country.
[0006] To sum up, in view of the differences in the classification of saline-alkali soil in the north and south of my country's coastal areas, in order to solve the contradiction between the single composition of traditional chemical amendments and the poor sustainability of the improvement effect and the slow effect of biological improvement but the long-lasting effect of the improvement and the improvement of coastal saline-alkali soil soil Fertilization and other issues, the development of a general-purpose compound improver suitable for saline-alkali soil improvement in the north and south coastal areas of my country is of great significance for reducing the cost of coastal saline-alkali soil improvement and commercializing it

Embodiment 1

[0032] Prepare the coastal saline-alkali soil modifier according to the following steps: take industrial waste gypsum and crush it, then mix the crushed industrial waste gypsum, monosodium glutamate residue, and water in a mass ratio of 30:1:2, and use a ball mill for 60 minutes to obtain an emulsion. Dry, to obtain industrial waste gypsum and monosodium glutamate waste residue mixed ground, wherein the industrial waste gypsum is phosphogypsum (by-product of phosphate fertilizer), the mixed ground is passed through a 50-200 mesh sieve (with a particle size of 75-270 μm); A fresh sample of plant waste is crushed into a size of 1cm by a crusher (model: ZP1400-700) and then subjected to aerobic composting. After it is mature, it is crushed for a second time and sieved into a particle size of 1mm for use; and then 10 parts by weight Parts of industrial waste gypsum and monosodium glutamate residue mixture, 35 parts of garden plant waste secondary crushed clinker, 0.02 parts of anion...

Embodiment 2

[0043] Prepare the coastal saline-alkali soil improver according to the following steps: first add industrial waste gypsum, MSG waste residue, and water in a ratio of 30:1:2, use a ball mill for 60 minutes to obtain an emulsion, and dry it to obtain industrial waste gypsum and MSG waste residue. Mixed grind, the industrial waste gypsum is desulfurized gypsum (by-product after flue gas desulfurization); then fresh samples of garden plant waste are pulverized into a size of 3 cm by a grinder (model: ZP1400-700) and then subjected to aerobic composting. After being decomposed, it is smashed for a second time, and then sieved into a particle size of ≤10mm for use. 20 parts by weight of industrial waste gypsum and monosodium glutamate residue mixture, 55 parts of garden plant waste, second pulverized decomposed clinker, 0.08 parts of anionic PAM (The molecular weight is 10 million and the degree of hydrolysis is 30%). Mix well; then add 15 parts by weight to the above mixture, which ...

Embodiment 3

[0047] Prepare the coastal saline-alkali soil modifier according to the following steps: take industrial waste gypsum and crush it, then mix the crushed industrial waste gypsum, monosodium glutamate residue, and water in a mass ratio of 25:1:2, and use a ball mill for 60 minutes to obtain an emulsion. Dry, to obtain industrial waste gypsum and monosodium glutamate waste residue mixed ground, wherein the industrial waste gypsum is phosphogypsum (by-product of phosphate fertilizer), the mixed ground is passed through a 50-200 mesh sieve (with a particle size of 75-270 μm); A fresh sample of plant waste is crushed into 1cm size by a crusher (model: ZP1400-700) and then subjected to aerobic composting. After it is mature, it is crushed again and sieved into a particle size of 1mm for use; then the weight is 5.2 Parts of industrial waste gypsum and monosodium glutamate residue mixture, 30 parts of garden plant waste secondary crushed clinker, 0.01 parts of anionic PAM (molecular weig...

Abstract

The invention discloses a seashore saline land improver, a preparation method of the seashore saline land improver and a seashore saline land improvement method. The seashore saline land improver comprises the following components in parts by mass: 5-20 parts of industrial waste gypsum, 0.2-1 part of monosodium glutamate waste residue, 30-60 parts of plant waste ground and decomposed material, 0.01-1 part of anionic polyacrylamide and 5-15 parts of bacillus flora. The seashore saline land improver is applicable to seashore saline areas in both north and south China and can rapidly improve the saline land within 50-70 days, and the salinity of the saline land is reduced to a concentration suitable for plant growth. Moreover, the improver has excellent fertilizer maintenance and salinity reduction effects and can achieve the effects of improving the pore structure of soil and reducing the volume weight of soil.

Description

Technical field [0001] The invention relates to the technical field of soil improvement, in particular to a coastal saline-alkali soil improver, a preparation method thereof and a coastal saline-alkali soil improvement method. Background technique [0002] my country’s coastal saline-alkali land now has a coastline of about 18,000 km, which has a wide distribution area. The coastal saline soil, tidal flat and shallow sea within the 15m isobath in the coastal area have 14 million hm 2 , Accounting for nearly 40% of the total area of ​​saline soil in my country. Coastal saline-alkali soils are mainly distributed in the eastern coastal areas of the North China Plain, such as Liaodong Bay, Bohai Bay, Laizhou Bay and coastal areas of Jiangsu and Zhejiang. Among them: the coastal saline soils of Jiangsu, Shandong, Hebei and Liaoning provinces north of the Yangtze River estuary have an area of ​​1 million hm 2 The area of ​​coastal saline soil in Zhejiang, Fujian, Guangdong, Guangxi, Ha...
