Embodiment 1
[0029] Heat 94 parts of quartz sand with a particle size of 0.2-0.4mm to 200°C, remove the moisture on the surface, and let it stand; when it is cooled to 70°C, add it to the stirring pot, and add 4 parts of fluorine modified Stir the silicone resin and 0.4 parts of m-phenylenediamine evenly; then add 1.2 parts of polytetrafluoroethylene micropowder with a particle size of 5-70um and 0.4 parts of nano-SiO with a particle size of 5-80nm 2 and stir evenly to prepare the superhydrophobic particles used for water storage in the surface layer.
[0030] Lay 1.5cm thick super-hydrophobic particles at a depth of 15cm under the sandy soil, plant 20g of rhododendron seeds in the sandy soil, and set the sandy soil without super-hydrophobic particles as the control group. After the seeds are sown, water every half a month 1 water, observe its survival rate. After 3 months, the survival rate of rhododendrons on the sandy soil with super-hydrophobic particles was 92%, while the survival ra...
Embodiment 2
[0032] Heat 92 parts of tailings with a particle size of 0.1-0.3mm to 180°C, remove the moisture on the surface, and let it stand still; when it cools to 60°C, add it to the stirring pot, and add 4 parts of polymethyl Silicone resin and 0.8 parts of hexamethylenediamine are stirred evenly; then 2.6 parts of polyorganosilicon powder water-repellent with a particle size of 5-70um and 0.6 parts of nano-CuO with a particle size of 5-80nm are sequentially added, and stirred evenly to obtain The superhydrophobic particles used for surface water storage.
[0033] Lay 2cm thick super-hydrophobic particles at a depth of 20cm under the sandy soil, plant 20g rose seeds in the sandy soil, and set the sandy soil without super-hydrophobic particles as the control group. Second water, observe its survival rate. After 3 months, the survival rate of roses on the sandy soil with super-hydrophobic particles was 90%, while the survival rate of roses on the sandy soil without super-hydrophobic pa...
Embodiment 3
[0035] Heat 90 parts of fly ash with a particle size of 0.08-0.2mm to 150°C, remove the moisture on the surface, and let it stand still; when it is cooled to 50°C, add it to the stirring pot, and add 6 parts of acrylic resin Stir well with 1 part of pyridine; then add 2 parts of polyvinylidene fluoride micropowder with a particle size of 5-70um and 1 part of nano-TiO with a particle size of 5-80nm 2 and stir evenly, that is, the superhydrophobic particles for surface water storage are prepared.
[0036] Lay 1cm-thick super-hydrophobic particles at a depth of 15cm under the sandy soil, plant 20g of jasmine seeds in the sandy soil, and set the sandy soil without super-hydrophobic particles as the control group. After the seeds are sown, water once every half a month Water, observe its survival rate. After 3 months, the survival rate of jasmine was 95% in the sandy soil with super-hydrophobic particles, and 0 in the sandy soil without super-hydrophobic particles.
