Abstract

The treatment of polyethylene film in farmland mainly relies on residual film recycling machinery. However, there is a lack of detailed reports on the characteristics of agricultural residual film recycling machinery and guidance direction for further optimization. This article conducted a detailed literature review, first introducing the hazards of pollution. Then, the operational principles of residual film mechanized recycling equipment were explained from three aspects. Finally, the research direction of residual film pollution control equipment is clarified: it is urgent to reduce the impurity content in residual film and facilitate the resource utilization.

Abstract in Chinese

规模化地膜覆盖栽培技术在高寒干旱地区应用广泛。农田残留膜污染问题因其严重影响农田耕作质量、生态环境和农业可持续发展而备受关注。目前，可生物降解塑料薄膜尚未得到广泛应用，因此聚乙烯薄膜仍然是主流的塑料薄膜材料。农田聚乙烯薄膜的处理主要依靠残膜回收机械设备。然而，目前还没有关于农业残膜回收机械特性的详细报道，也缺乏对残膜回收机器进一步优化的相关指导方向。本文对农残膜回收机进行了详细的文献综述，首先介绍了农残膜污染的危害；然后，从三个方面阐述了操作原理：苗期地膜、耕作层残膜、表层全膜机械化回收设备；聚乙烯农用薄膜需要与农用薄膜、机械和农艺要求相结合，才能实现完全回收；最后，明确了残膜污染控制设备的研究方向：迫切需要降低残膜的杂质含量，促进残膜的资源化利用。
