Research status and development trend of tillage layer residual film recycling machine

The extensive mulch application in agricultural production simultaneously brings economic benefits and farmland pollution. Mechanized recovery is a necessary part of the treatment of residual film pollution, and the mechanized recovery of residual film in the tillage layer is a heavy difficult point. The lack of efficient and stable tillage layer residual film recycling machines in China not only hinders the process of residual film pollution control, but also restricts the green and sustainable development of agriculture to a certain extent. For this, the harm of film residue and current situation of tillage residual film pollution are summarized and analyzed, the current domestic tillage layer residual film recovery machines are compared and analyzed, and the structural principle and characteristics of residual tillage film recycling machines in China are highlighted, and some problems are pointed out, including the lack of research on film-soil separation mechanism in China, the insufficient working depth of recycling machines, which need to be tilled and recycled next year, the low degree of automation and intelligence and the less of compound tillage layer residual film recycling machine. Combined with China′s national conditions, some development suggestions are put forward, such as developing an active film picking mechanism to improve the intelligence and accuracy of the film-picking component, combining with pollution monitor device to study the classification of residual film pollution in farmland, developing the combined operation machine of tillage layer residual film recovery and tillage and land preparation to reduce the cost of treatment, so as to provide reference for the treatment of farmland residual film pollution and the development of tillage layer residual film recycling machine.
