Embodiment 1
[0020] Embodiment 1: Use coal-based bio-soil A formula, the content of each component is: 35% of weathered coal, 40% of fly ash, 14% of coal gangue, 10% of bentonite, 0.2% of water retaining agent, and 0.8% of soil stabilizer. Using this embodiment as a substrate to plant alfalfa, compared with the western desertified soil, the plant biomass increased by 20%.
Embodiment 2
[0021] Embodiment 2: Use coal-based bio-soil A formula, the content of each component is: weathered coal 55%, fly ash 8%, coal gangue 35%, bentonite 1%, water retaining agent 0.9%, soil stabilizer 0.1%. Using this embodiment as a substrate to plant alfalfa, compared with the western desertified soil, the plant biomass increased by 25%.
Embodiment 3
[0022] Example 3: Coal-based bio-soil B formula is used, the content of each component is: weathered coal 35%, fly ash 35%, peat 28%, bentonite 1%, water retaining agent 0.9%, soil stabilizer 0.1%. Using this embodiment as a substrate to plant alfalfa, compared with the western soil, the plant biomass can be increased by 35%.
