地膜机械覆盖栽培技术广泛推广应用,明显提高了农作物产量和土地产出能力,不仅使粮食大面积增产,而且对发展特色优势产业、保障粮食安全、推动农村经济持续发展起到了积极作用。但随着农膜使用量逐年增加,造成的污染问题也日趋严重,大量废旧农膜和塑料包装材料的随意弃置,破坏自然景观,影响环境卫生,造成资源浪费。特别是残留在土壤中和土壤肥力水平,导致作物减产。基于此,对宁夏隆德县农用残膜治理提出应对措施。
The widespread application of plastic film mulching cultivation technology has obviously improved crop yield and land output capacity, not only increased large-scale grain production, but also played a positive role in developing characteristic advantageous industries, ensuring food security and promoting the sustained development of rural economy. However, with the increasing use of plastic sheeting, pollution caused by the problem has become increasingly serious, a large number of discarded plastic sheeting and plastic packaging materials at random disposal, damage to the natural landscape, affecting environmental health, resulting in waste of resources. In particular, residues in soil and soil fertility levels have led to crop cuts. Based on this, countermeasures are proposed for the treatment of agricultural residues film in Lund County of Ningxia.
