Example Embodiment
[0022] Example one
[0023] A nutrient soil for planting landscaping seedlings, comprising the following steps:
[0024] S1. Pretreatment: pulverize the urban domestic sludge, pass through a 300-500 mesh sieve to remove large particles in the domestic sludge, add water to cover the domestic sludge, and add hydrated lime and sodium thiosulfate, and aeration Keep the air at the first temperature and stir for the first time to obtain deodorized sludge;
[0025] S2. Composting fermentation: deodorizing sludge with a first moisture content ratio, adding active microorganisms to the deodorizing sludge, adding straw and biochar, controlling the first temperature and fermenting for the second time;
[0026] S3. Decomposition: Dehydrate the fermented sludge prepared by S2 to the second moisture ratio, add the modified substance to mix, and finally put it into the decomposed bin until the temperature drops to the second temperature to obtain nutrient soil;
[0027] S4. Detection: Detect the cont...
