National Key Research and Development Program of China (Nos. 2016YFD0200302)
Continuous cropping obstacle seriously affects crop yield and quality. Research and development of efficient prevention technology is the key to achieve sustainable intensive agricultural production. By using the incoPat technology innovation information platform, we searched and analyzed home and abord patents of continuous cropping obstacle prevention technology from 2000 to 2019. From the number of patent applications, technical composition, regional distribution, main applicants, legal status and other aspects, we revealed the research and development status, technology development trend and production, education and research status. The results showed that in recent years, the number of patents had increased dramatically. Combined with the development of the modern biology and material technologies, new researches have fully considered the combination of the application of biological prevention and control technology. Patent applicants in China were mostly enterprises and individuals. The conversion rate of patents applied by universities and scientific research institutes was not very high, and the number of patent jointly applied by universities/scientific research institutes and enterprises was also small. Technology application has become the hotspot, and new biological and material technological achievements are introduced into the development of technology. The cooperation of industry-university-research and the quality of patented technology in China urgently need to be strengthened.
