Abstract： |
The present invention relates to a new usage for the coal desulfuration magnesium slag and a method for the desert control, in particular to a method adopting the coal flue gas desulfuration wastes to control the desert, which is primary to perform the sampling analysis of the soil to get the total salt quantity and quantity of the MgSO4, MgC12 at different sections; the consumption volume of the coal flue gas desulfuration magnesium slag that is needed to be applied is calculated according to the salt content of the soil in the desert; appropriate extreme xerophytes that are suitable to be planted in the desert district are selected; during the planting, the flue gas desulfuration magnesium slag of different proportion is added into the underground soil separately according to the salt content of the soil and the distribution of the salt on the section; the high water-absorption resin that can absorb the water adequately is added at the place 40 cm to 50 cm below the ground; finally the plants are managed like the normal planted plant. Adopting the present invention, on the one hand, the coal flue gas desulfuration wastes are utilized economically and efficiently, which converts the waste into treasure; on the other hand, the present invention provides a desert control method having the advantages of rapid improvement, good effect, less water consumption, good economic benefit and favorable application prospect. |
