firstly, adding water into bone meal to prepare bone meal slurry, uniformly stirring and mixing the bone meal slurry and N, N-dimethylformamide, granulating, and continuously spraying sulfur molten liquid onto micro spherical particles after micro spherical particles with diameters larger than 0.5mm appear; then drying and sieving are carried out, and the spherical particles are led into a roller; heating paraffin to 65 ℃ for melting, crushing 3, 4-dimethylpyrazole phosphate and potassium dihydrogen phosphate to more than 200 meshes, adding the crushed powder into the melted paraffin, and uniformly stirring to obtain a mixture A; and spraying the mixture A on the surfaces of the spherical particles in the roller, introducing the spherical particles into a drying cylinder after uniform spraying, and rapidly cooling by blowing 10-15 ℃ airflow by using an air cooler to obtain the modified bone meal.
6. The soil remediation agent of claim 1 wherein the auxiliary agent comprises a microbial agent and chitin.
7. The soil remediation agent of claim 6, wherein the microbial agent and chitin are present in a weight ratio of 5: 1.
8. the soil remediation agent of claim 7 wherein said microbial agent is a bacillus licheniformis, photosynthetic, trichoderma harzianum bacterium in a 5: 2: 1, and the effective viable count of the microbial inoculum is more than or equal to 2.0 hundred million/g.
9. A method of preparing a soil remediation agent as claimed in any one of claims 1 to 8 including the steps of:
s1, adding the modified potassium fulvate into diatomite, stirring, and roasting at 200-250 ℃ for 2-3 hours to obtain an activated roasting material;
s2, adding the limestone, the iron phosphate and part of water into a normal-pressure reaction container, stirring and heating to 70-90 ℃, adding the activated roasting material for pre-reaction to obtain a pre-reactant;
s3, transferring the pre-reactant into a high-pressure reaction container, heating to 130-145 ℃ in a closed state, and reacting for 2-3 hours under the pressure of 0.2-0.25MPa to obtain a semi-finished product of the repairing agent;
s4, mixing the semi-finished repair agent, the modified bone meal and the auxiliary preparation, adding the rest water, mixing uniformly, drying at low temperature, and granulating to obtain the finished repair agent.
