Abstract: In order to clarify the bottleneck problems restricting the development of oil-seed camellia industry, the paper reviews its development history and summarizes its current development status, breeding, cultivation, processing and scientific and technological service, and then put forward the corresponding suggestions. It is proposed to strengthen the supervision of seed selection and breeding, and limit the popularization and application of the seeds of low recognition, to establish dynamic evaluation and reward & punishment mechanism of good seeding base and increase the fund input to the breeding, to improve the current nursery by raising the admittance threshold, to expand the use of fine varieties and strengthen the training of breeding techniques, to make a regional refinement of high efficiency cultivation and low yield forest improvement technology, to set up high-yielding demonstration bases and expert banks to guide operators in scientific management, to promote the mechanization of the whole oil-seed camellia industry chain for improving the processing technology, to develop quality standards for camellia oil products and establish a public service platform for the high-quality development of the industry, and to strengthen the public brand building and publicity and raise consumers' awareness of camellia oil brands. It is expected that these suggestions will help the high-quality development of camellia oil industry and accelerate its scale-up from 100 billion to 1 trillion.
