| Planting plant | Robinia pseudoacacia |
| Treatment cost (Wanyuan/mu) | 0.7 (without soil discharge, flat cost) |
| Survival rate | 99.15％ |
Example 2
The same as example 1, except that in example 2, a 60-degree soft foundation slope was selected and 3 robinia pseudoacacia seedlings were planted in a nutrition pot.
As shown in table 2:
| mine species | Vanadium titano-magnetite |
| Treatment area | 60-degree soft foundation side slope |
| Area of treatment | 45 mu |
| Planting plant | Robinia pseudoacacia |
| Treatment cost (Wanyuan/mu) | 0.7 (without soil discharge, flat cost) |
| Survival rate | 99.03％ |
Example 3
The same as example 1, except that in example 2, a 60-degree soft foundation slope was selected and 5 locust seedlings were planted in a nutrition pot. As shown in table 3:
comparative example 1
