Abstract： |
The invention discloses a home position restoring method of biological reinforced alkaline polluted soil in the environmental restoring technique, which is characterized by the following: adding biological degradation bacteria in the alcaline polluted soil; using mechanic digging method to construct loose biological layer in the salt immersing course; blocking capillary phenomenon to avoid salt return phenomenon; improving the efficiency of water immersed salt; modifying the crumb structure and fertility of alcaline soil; restoring the planting ability of the soil with widely extending prospect in the pollution harnessing course. |
