The invention discloses a polyethylene or polypropylene resin mulched hollow plastic ball used in arid and semi-arid areas and a method for using the same. The main raw material of the mulched hollow plastic ball is polyethylene or polypropylene resin, and a certain amount of resin is added to the resin. Carbon black can achieve the effect of heat absorption and heat preservation, increase the heat preservation effect of the mulch film, add a certain amount of paraffin wax, anti-light stabilizer, and antioxidant to the resin, and prolong the degradation cycle; evenly arrange the hollow plastic balls of the mulch film by putting it into the machine Lay and bury in the farmland to form a mulch, forming an insulation layer that can not only prevent water evaporation, reduce water volatilization, ensure soil moisture, but also have the effect of inhibiting the growth of weeds, saving the construction cost of farmland, and plastic balls can be easily recycled There are no microplastic residues, no need for pesticide spraying, no pollution problems such as pesticide residues, less long-term investment, and low cost. |
