In order to reveal the technological development and innovation subjects in rape fertilization field, the proprietary technologies of rapeseed fertilization field have been analyzed from four dimensions of time, space, technology and application. Focusing on longitudinal analysis through three subdivisions of fertilizer research, fertilization technology and fertilization machinery to provide information support for the green sustainable development of rapeseed fertilization field. The results showed that China is the main technology source country in rapeseed fertilization field, which number of patent applications account for 76% of the global total. At present, the overall development level of rapeseed fertilization field is slow, fertilizer research subdivision has sinked into technical bottlenecks, the subdivisions of fertilization technology and fertilization machinery are still in the budding or rapid growth period, and the development of innovative rape fertilization technology is slightly insufficient. Scientific institutions are important patent applicants of China in rapeseed fertilization field, but have low market interlinkage. In summary,there are some problems in rapeseed fertilization field such as unbalanced development of subdivisions,disconnection between technology research and market demand, etc. It is proposed to strengthen the research and development of core technologies in each subdivision, clarify the market orientation of research and development investment, promote the six-in-one collaborative innovation of “government,industry, academia, research, use and service”, to achieving the green sustainable development of rapeseed fertilization.
