Abstract: The technical information of Chinese cabbage invention patents was analyzed using bibliometric analysis combined with expert analysis.The results showed that the changes in the number of Chinese cabbage invention patents both in China and abroad have gone through the initial stage, the slow growth stage, the rapid growth stage and the decline stage, and the changes in foreign periods were earlier than those in China.Compared with foreign countries, in China the research of Chinese cabbage invention patent technology was still relatively active.In China the fields with the largest number of Chinese cabbage invention patent applications were cultivation, processing and biotechnology in turn, and in foreign countries were processing, biotechnology and breeding.The development trend of Chinese cabbage invention patent literature was further analyzed by subdividing the technical direction.The results showed that the numbers of patent applications in planting technology and soil fertilizer directions was the largest, while the numbers of patent applications in breeding and seed production technology, molecular markers, plant and harvest mechanization directions increased significantly during recent years, indicating that these research directions were the current research focus of Chinese cabbage invention patent technology.
