Embodiment 1
[0049] A coal mining area in Hami City has a typical continental climate, with an annual average temperature of 9.8°C, an extreme maximum temperature of 43°C, and an extreme minimum temperature of -32°C; annual precipitation of 33.8mm, annual evaporation of 3300mm, annual average sunshine of 3358 hours, and a frost-free period 182 days.
[0050] Specific implementation steps
[0051] S1. Mix and prepare desert soil, sand, domestic sludge and fly ash according to the weight ratio of 6:2:1:1 to obtain the formula soil;
[0052] S2. Dig planting pits. The depth of the planting pits should at least exceed the thickness of the saline-alkali soil. Fill the planting pits with formula soil to form a filling layer, and then dig out planting holes in the filling layer.
[0053] S3. Plant arbor plants and shrub plants in the planting holes, intercropping with grids, choose Populus euphratica for arbor plants, Haloxylon for shrub plants, ryegrass and tall icegrass for herbaceous plants, ...
