基于专利信息的施肥机械化技术发展与竞争态势分析

Analysis on the development and competitive situation of fertilizer mechanization technology based on patent information

以国内外施肥机械技术领域专利为研究对象,研究施肥机械专利技术总体发展现状、趋势与技术竞争态势,为本领域相关技术研究人员提供参考。检索1997—2017年间国内外施肥机械技术相关的专利文献,运用文献调研、专利地图、专利引证等方法进行研究。分析施肥机械技术领域专利技术发展现状与趋势、专利技术主题分布情况和技术热点、专利竞争态势及中国所处的位置、重要专利权人及其重点研究方向。结果表明:国内外施肥机械行业正处于快速成长期;中国在该领域专利申请数量占据绝对优势,但原创性技术偏少;中国在气力式辅助输送、水稻插秧同步施肥、有机肥撒施、农机智能化等技术热点方向,需要重点关注,加强研究。

Taking patents of fertilizer mechanization technology as the research object,the overall development status,trend and technical competitive situation of fertilizer machinery patent technology were studied.The results can provide a reference for the relevant technical researchers in this field.The domestic and foreign patent documents related to fertilizer machinery technology from 1997 to 2017 were searched,and patent analysis methods such as literature research,patent map,technology life cycle,patent citation were used to analyze.The development status and trend of patent technology in the field of fertilizer machinery technology,the distribution of patent technology themes and technology hotspots,key patentees and their key research directions in this field,the patent competition situation in the field of fertilizer technology and the position of China were analyzed.The results show that:at present,the fertilization mechanization technology is in the rapid growth period at home and abroad.It has an absolute advantage in the number of patent applications in this field of China,but the original technology is relatively small in China.It needs to focus on and strengthen research in such hot technical directions as pneumatic auxiliary transportation,rice transplanting and synchronous fertilization,organic fertilizer distribution,intelligent agricultural machinery in China.
