塑料问世后,即被人们广泛地应用到了几乎所有的领域。但是,在塑料应用极大地促进工农业生产发展,丰富和改善人们物质文化生活的同时,也带来严重的“白色污染”问题。塑料不会自行“腐烂”,如果塑料薄膜长期存在于田间,不仅妨碍耕作,而且破坏土壤自身的水肥及微生物平衡,对农作物生长造成不利影响。发达国家对使用后的塑料曾采用过掩埋、焚烧和回收利用等方法进行 After the advent of plastics, it was widely used in almost all fields. However, the application of plastics has greatly promoted the development of industrial and agricultural production, enriched and improved people’s material and cultural life, and at the same time brought serious “white pollution” problems. Plastics do not “rot” on their own. If plastic films remain in the field for a long period of time, they will not only impede cultivation, but also damage the soil’s own balance between water, fertilizer, and microorganisms, and adversely affect the growth of crops. Developed countries have used landfills, incineration and recycling methods for used plastics.
