Method for protecting soil slope from rain erosion by improving with phosphogypsum and a microbe
The present invention provides a method for protecting a soil slope from rain erosion by improving with phosphogypsum and a microbe. The method includes: (1) placing Bacillus pasteurii in a culture medium to prepare a microbial solution, and mixing urea, calcium chloride and water to 5 prepare a cementing solution; (2) mixing a mixture, the microbial solution and water well, and adding the cementing solution and water to prepare an improving mixture slurry; and (3) spraying the improving mixture slurry to a face of the slope twice by wet spraying, mixing the improving mixture slurry with grass seeds well, spraying to the face of the slope once, covering with a non-woven fabric by tying and fixing, and watering every day. The method meets the requirements 10 of rain erosion resistance and greening protection for soil slopes, such as less and gravelly soil slopes. It reduces the stock of phosphogypsum, thereby reducing the occupation of cultivated land, and promotes plant growth with available phosphorus in the phosphogypsum. The microbial improvement of the phosphogypsum achieves the immobilization of harmful elements, thereby reducing environmental pollution.
