Embodiment 1
[0048] see figure 1 , a method for remediation of heavy metal-contaminated soil with the root diffusion capsule, comprising the following steps:
[0049] S1. First, excavate planting pits on the target repaired soil according to the planting method of plants that can absorb heavy metal soil;
[0050] S2. Please refer to figure 2 , a in the figure represents a plant seed, and the self-disintegrating capsule 1 wrapped with the plant seed is buried in the planting pit, and fertilization and watering are carried out according to the growth needs of the plant seed;
[0051] S3. After a period of time, the plant seeds take root and germinate, and produce a pressing force on the self-disintegrating capsule 1 from the inside out, and the root system of the plant seeds penetrates into the gap holes on the surface of the self-disintegrating capsule 1 and extends into the soil;
[0052] S4. Under the force of the root system extending into the soil, the self-disintegrating capsule 1 d...
