棉田残膜回收机研究进展与展望OA

The application of plastic soil-film covering technology can effectively increase cotton yield,but the residual plastic film in cotton fields can damage soil structure,reduce soil fertility,which is not conducive to the sustainable development of cotton fields.The current methods for treating residual film pollution include degradation of plastic film,manual recycling,and mechanical recycling.Mechanized recycling is currently the most effective way to treat residual film pollution,and residual film recycling machines have become an important means of treating residual film pollution.Based on the structural types and principles of the residual film collection devices,the technical principles of various residual film recovery machines suitable for cotton,such as the tooth chain type,the telescopic rod tooth type,the rotary tiller tooth type,the spring tooth type,the drum type and the rotating drum type,are summarized and reviewed.In the future,the performance of residual film recovery machines should be improved in terms of intelligence,comprehensive film collection performance,separation rate of film debris and winding rate.
