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...
