[0022] The application effects of the present invention are further described below through examples, but the present invention is not limited.
[0023] The implementation process is as follows:
[0024] 1) First, the basic physical and chemical properties of the soil were measured. The average oil content of the oil-polluted soil was 2.89%, the soil viscosity was relatively high, the pH value was slightly alkaline, the total nitrogen content was 0.26g / kg, the water holding capacity was 5.51%, and the number of local hydrocarbon-degrading bacteria was 0.08×10 4 MPN, the salt content is 15.31g / kg;
[0025] 2) Crush the oil-contaminated soil from the surface to a depth of about 30cm, add 20g / kg of yellow sand to the soil, add 10g / kg of weed debris, add 15g / kg of organic fertilizer, apply 15g / kg of agricultural compound fertilizer, and 10g of agricultural water-retaining agent / kg, mix and mix the above conditioner with the soil;
[0026] 3) Turn the soil 1-2 times a week, and...
