The invention belongs to the field of
environmental protection and
engineering construction, and discloses a preparation method of a water-retention, dust-suppression and green-
recovery environment-friendly material and an application thereof. A water-retaining, dust-suppressing and green-
recovery agent A is prepared from a
calcium-based material, a
plant growth regulator, grass seeds and water, and a water-retaining, dust-suppressing and green-
recovery agent B is prepared from a natural
polysaccharide material and water. In
industrial land,
desertification land,
greening land and sites where soil
pollution treatment is completed, the water-retaining, dust-suppressing and green-recovery agent A is evenly sprayed on the
soil surface of the sites without soil turning treatment, and after spraying is completed, the water-retaining, dust-suppressing and green-recovery agent B is evenly sprayed on the
soil surface of the sites without soil turning treatment, and manual watering and fertilization are not needed subsequently. The water-retaining, dust-suppressing and green-recovery agent can be sprayed to achieve the effect of inhibiting flying dust of
field soil for a long time, the
germination speed of grass seeds in the material is high, the green-recovering speed is high, the maintenance time is long, and flying dust can be inhibited. By means of the method, flying dust generated by site soil can be efficiently treated within a short time, and generation of the flying dust is continuously inhibited through the further fixing effect of grass plants.
