Method for controlling desertification by waste plastic bottles

Abstract

The invention discloses a method for controlling desertification by waste plastic bottles. The recycled and classified waste plastic bottles are heated, pressurized, blown up and shaped into flat plastic bottles. The flat plastic bottles are filled with sandy soil and a small quantity of water and covered. The flat plastic bottles filled with the sandy soil are arrayed and tiled on desertified land according to plant requirements, and plants are planted at exposed positions. The method has the advantages that the sandy soil can be immediately controlled to flow along with wind and rain, the rain can permeate into the land from surroundings and can be stored, exposed water evaporation area only accounts for 15% of covering area, so that proper water is provided for plant growth, the survival rate of the plants and living environments are improved, the plastic bottles resist aging and can achieve long-term control effects, long-term benefits are achieved by performing control once, control cost is low, resources are rich, the price is low, and a control project is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of desertification control, in particular to using waste plastic bottles to control desertification. Background technique [0002] The climate conditions in desertified areas are relatively harsh, and the land is dry and rainless. Desertified land control mainly includes biological methods, mechanical engineering methods, and chemical material methods. Engineering sand control mainly achieves the purpose of reducing desert migration through engineering construction methods such as windbreak walls and grass grids; chemical sand control sprays sand-fixing agents such as asphalt and resin on the sand surface to form a consolidation layer to achieve the purpose of fixing the soil; biological control The sand is windproof and sand-fixed by planting drought-resistant desert plants and other methods. However, the above-mentioned technical means have the disadvantages of high cost of windbreak and sand fixation, s...

AI Technical Summary

Problems solved by technology

However, the above-mentioned technical means have the defects of high cost of windproof and sand fixation, short service life, low conservation and utilization of water resources, and large workload and high maintenance cost of vegetation maintenance in the later period.
