Embodiment 1
[0024] An environment-friendly soil restoration agent, the main components of the soil restoration 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, 13 parts of organic acid 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 quinoa enzymatic hydrolysis product, and its preparation method is: S1. Crush the quinoa with a mixer, add water at a ratio of 1:5, soak at 65°C for 10 minutes, and filter to obtain a filter residue; S2. Add water according to the solid-to-liquid ratio of 1:2, mix evenly, pretreat in a microwave with a power of 350w for 1min, add cellulase, and the enzyme dosage is 600U·g -1 , pH value 4.0, enzymolysis temperature 50°C, reaction time 8h, after the reaction, inactivate the enzyme in a boiling water bath for 10min...
