Example Embodiment

[0023] Example 1
[0024] An environmentally friendly soil remediation agent. The main components of the soil remediation agent include, in parts by weight: 64 parts of shell powder, 21 parts of sodium dihydrogen phosphate, 16 parts of proline, 9 parts of histidine, and 13 parts of organic acid. Part, 52 parts of enzymolysis product A, 11 parts of enzymolysis product B, 7 parts of vitamin C.
[0025] In particular, the organic acid is citric acid.
[0026] Further, the enzymatic hydrolysis product A is an enzymatic hydrolysis product of quinoa, and its preparation method is: S1. The quinoa is crushed with a blender, and the amount of water is 1:5, after which it is soaked at 65°C for 10 minutes, and filtered to obtain a filter residue; S2. Add water according to the solid-liquid ratio of 1:2, mix well, pretreat it in a microwave with 350w power for 1 min, add cellulase, and the enzyme dosage is 600U·g -1 , PH 4.0, enzymatic hydrolysis temperature 50°C, reaction time 8h, after the reaction, inactivate the enzyme in a boiling water bath for 10 minutes to obtain enzymatic hydrolysis solution; S3. The enzymatic hydrolysis solution is spray-dried to obtain enzymatic hydrolysis product A.
[0027] Further, the enzymatic hydrolysis product B is an enzyme-hydrolyzed product of Artemisia annua, and its preparation method is as follows: S1. Dry Artemisia annua at 80°C to a constant mass, pulverize it through a 20-mesh sieve, and reserve; S2. , Use 0.5% sulfuric acid at 80°C, stir for 30 minutes at a solid-liquid ratio of Artemisia powder: sulfuric acid=1:5, centrifuge at 5000 rpm for 5-10 minutes, and take the precipitate; S3. Enzymatic hydrolysis, enzymatic hydrolysis conditions: The precipitate is added with water according to the solid-liquid ratio of 1:3, and cellulase is added. The amount of enzyme is 100U·g -1 , PH 4.0, enzymatic hydrolysis temperature 45°C, reaction time 34h, after the reaction, inactivate the enzyme in a boiling water bath for 10 minutes to obtain an enzymatic hydrolysis solution; S4. The enzymatic hydrolysis solution is spray-dried to obtain an enzymatic hydrolysis product B.
