Step 2, by the first mixture obtained by step 1 and raw cattle and sheep excrement, slag is native, and humic acid is well mixed, and obtains the
Two mixtures；
Step 3, the second mixture obtained by step 2 is added into water and fermenting agent carries out heap fermentation, obtain flyash
Base artificial soil.
Further, the acid in step 1 includes but is not limited to hydrochloric acid, nitric acid, sulfuric acid, phosphoric acid and hydrofluoric acid.
Further, in step 1, total acid concentration is 0.1%-10%.
Further, in step 1, flyash per ton adds sour 1-100 liters.
Further, in step 2, by mass, fly ash content is 50-99% in the second mixture, and raw cattle and sheep excrement contains
It is 0-50%, content of humic acid 0%-30% to measure as 0%-50%, slag soil content.
Further, in step 3, the second mixture per ton adds water 100-1000 liters.
Further, the time fermented in step 3 is 7 days to 1 year.
Further, the fermenting agent in step 3 includes Lactobacillus plantarum, lactic acid bacteria, saccharomycete, bacillus, excrement intestines
One or more in coccus, protease.
Compared with prior art, the beneficial effects of the invention are as follows：Using cattle and sheep excrement, humic acid, slag soil, it is total to flyash
With fermentation, artificial soil is prepared, is improved for nursery and salt-soda soil earthing, can not only largely dissolve flyash, improves waste
Utilization rate, and economic benefit can also be produced.
