Embodiment 1
[0028] (1) Preparation of matrix raw materials:
[0029] Loam soil: Select the local surface soil, air-dry, crush, and pass through a 5mm sieve. The sand content in the soil is 3%, and the water content is 12%;
[0030] Mineral mixture: apatite, orthoclase, and medical stone are crushed, passed through a 5mm sieve, and the mass ratio of each component is apatite: orthoclase: medical stone = 2:3:1;
[0031] Expanded vermiculite: bulk density about 0.2g / cm 3 , water absorption is about 3 times, and the particle size of vermiculite is less than 3mm;
[0032] The plant fiber is made of corn and wheat straw as the main raw materials. The length after crushing is 3cm, and the ratio of corn and wheat straw is 2:8. The straw mixture is naturally fermented and decomposed for 30 days to form a plant fiber matrix;
[0033] Water retaining agent: the composition is potassium polyacrylate-polyacrylamide copolymer, the absorption rate of 0.9% saline solution is 50-100, the particle size i...
Embodiment 2
[0047] (1) The preparation of matrix raw materials is the same as in Example 1.
[0048] (2) The raw materials of the root induction layer are by mass fraction: loam 30, coal gangue after acidification 40, mineral mixture 10, plant fiber 12, and the rest are the same as in Example 1;
[0049] Mix and stir evenly, spray on the exposed rock surface with a sprayer, with a thickness of 10cm.
[0050] (3) The raw material of seed germination layer is by mass fraction: loam 75, expanded vermiculite 10, all the other are with embodiment 1;
[0051] Mix and stir evenly, and spray it on the surface of the root induction layer by a sprayer, with a thickness of 3cm. The time difference between the seed germination layer and the spraying time of the root induction layer is 18 hours, and finally carry out regular water conservation and management for 3 months.
[0052] After 6 months, the vegetation coverage reached more than 93%, and after 3 years of implementation, the vegetation covera...
Embodiment 3
[0054] (1) Preparation of matrix raw materials: apatite: orthoclase: medical stone = 1.5:2:1; the rest are the same as in Example 1.
[0055] (2) The raw materials of the root induction layer are calculated by mass fraction: 35% of loam soil, 35% of acidified coal gangue, and others are the same as in Example 1.
[0056] Mix and stir evenly, and spray it on the exposed rock surface with a sprayer, with a thickness of 12cm.
[0057] (3) The raw materials of the seed germination layer are calculated by mass fraction: loam 72, expanded vermiculite 13, and others are the same as in Example 1.
[0058] Mix and stir evenly, and spray it on the surface of the root induction layer by a sprayer, with a thickness of 2cm. The time difference between the seed germination layer and the spraying time of the root induction layer is 18 hours, and finally carry out regular water conservation and management for 3 months.
[0059] After 6 months, the vegetation coverage reached more than 92%, a...
