    新疆棉田残膜回收方式及资源化再利用现状问题与对策

    Problems and countermeasures of recycling methods and resource reuse of residual film in cotton fields of Xinjiang

    • 摘要: 地膜覆盖栽培技术在促进农作物增产增收的同时,地膜残留问题也给农业生产环境及生态环境带来了诸多危害,地膜使用与农业生态环境保护及农业绿色可持续发展之间的矛盾日益突出。新疆作为中国棉花主产区,受种植面积增长、长年连作、地膜强度差及回收力度不够等多重因素影响,棉田残膜污染问题尤为严重。该文在实地调研的基础上,分析归纳当前新疆棉田地膜使用基本状况及残留污染情况,以当前新疆棉田残膜回收方式及资源化利用情况为主要研究内容,对采用不同回收方式回收的棉田残膜特点进行分析。通过实地调查当前新疆残膜初清理方式、再加工处理工艺流程及利用途径等基本情况,分析了各生产环节配套设备及工作过程,结果表明:先进适用的农田残膜回收机械缺乏、机收棉田残膜含杂量较高、残膜初清理及再加工设备缺乏且技术不成熟、残膜初清理及再加工企业较少等是阻碍新疆农田残膜资源化利用进程的主要影响因素,建议通过加快耐候性及高强度地膜推广与示范,提升农田残膜机械化回收技术水平,合理布局残膜初清理及再加工企业等多种途径,实现地膜生产、使用、回收及资源化利用各环节协同推进,形成全产业链闭环残膜污染治理模式,全方位及多层次解决新疆农田残膜污染问题,为新疆乃至全国农田残膜污染治理及资源化利用提供一定借鉴与参考。

       

      Abstract: Plastic film mulching cultivation technology has functions such as improving crop growth environment and regulating crop growth cycle, and it has been widely used in agricultural production processes at home and abroad, and it has promoted agricultural productivity and agricultural industry development. But the problem of mulch film residue has brought many harms to the agricultural production environment and the ecological environment. The contradiction between the use of mulch film and the ecological environment protection of agriculture and the sustainable development of agriculture has become increasingly prominent. Xinjiang is the major cotton producing area in China, and the area covered by plastic film and the amount of its use rank first in the country, and the problem of residual film pollution in cotton fields in Xinjiang is particularly serious, which is affected by multiple factors such as growing planting area, continuous cropping, poor film strength and insufficient recycling. The problem of residual film pollution in cotton fields affects the growth and yield of cotton, and the quality of agricultural machinery operations has been reduced and the content of heterogeneous fibers in cotton textiles has exceeded the standard. In recent years, through the formulation and implementation of laws and regulations and the research and development of cotton film residual membrane mechanized recycling technology, the residual film pollution control work has achieved initial results, but residual film pollution control is a system engineering, and the problem of recycling but not using will cause secondary environmental pollution and effective use of resources. Based on the analysis and induction of the current basic use conditions and residual pollution situation of farmland mulch in Xinjiang, the paper took the current recycling method, the residual film preliminary cleaning method and resource re-utilization situation of cotton fields in Xinjiang as the main research content, and the characteristics of the residual film in cotton fields recycled by different methods were analyzed, the difficulty of initial cleaning and recycling of cotton film residues recovered by different methods was compared and analyzed. Through field investigations on the current basic conditions of the residual film preliminary cleaning method, reprocessing process flow and utilization methods in Xinjiang, the supporting equipment and working process of each production link were analyzed. The results showed that the main influencing factors that hindered the resource reusing process of residual film in cotton fields in Xinjiang were the lack of the advanced and applicable cotton fields residual film recycling machinery, higher residual film impurity in the cotton field harvested by machine, the lack of equipment and immature technology of the residual film preliminary cleaning and reprocessing method, the single cotton fields residual film recycling and reprocessing methods and products, and less residual film preliminary cleaning and reprocessing enterprises. Residual film recycling and resource re-utilization should be carried out in order to effectively solve the residual film pollution problem. Based on this, the coping strategies were proposed. It was recommended to accelerate the production and use of film by improving the weathering and high-strength film promotion and demonstration, improving the mechanized recycling technology of cotton fields residual film, developing suitable residual film preliminary cleaning and reprocessing technology, and rationally arranging the preliminary cleaning and reprocessing enterprises, recycling and reuse of all links to form a closed-loop residual film pollution control model for the entire industrial chain, comprehensive and multi-level solution to the problem of residual film pollution in cotton fields in Xinjiang, which were conducive to energy saving and emission reduction and sustainable development of agriculture and could provide some reference for farmland residual film pollution control and resource reuse in Xinjiang and even the whole country.
