摘要
地膜覆盖技术在农业生产中得到广泛应用,但随着覆膜年限和面积不断增加,残留地膜给环境带来严重污染.目前,机械回收是治理残膜污染的有效技术手段.对现有残膜机械化回收技术专利信息进行归纳总结,从申请时间、申请地区、专利权人类型和技术特征等方面阐述残膜机械化回收技术发展趋势.从机械化角度分析残膜回收技术专利失效的主要原因,对不同申请主体的专利失效现象进行剖析,更好地理解专利失效背后的原因.结合现有专利技术热点和发展趋势,提出促进残膜机械化回收技术的发展建议.
Abstract
Plastic film covering technology has been widely used in agricultural production,but with increasing number of years and areas covered with plastic film,residual plastic film has brought serious pollution to environment.At present,mechanized recovery is an effective technical means for treating residual film pollution.An in-depth analysis of existing patent information for mechanized recov-ery of residual film was conducted,and development trend of mechanized recovery technology of residual film was elaborated from as-pects of application time,application area,patent holder type,and technical characteristics.Main reasons for patent invalidation and phenomenon of patent invalidation among different applicants were analyzed.Propose suggestions for promoting development of mech-anized recovery technology for residual film were put forward based on existing patent technology hotspots and development trends.
