Hainan's betel nut processing industry continues to develop, and the yield has reached 231000 t. There are some problems in betel nut industry such as unreasonable initial processing layout, processing capacity surplus, and deep processing industry lag. It is suggested that we should guide the initial processing layout of betel nut according to local conditions, and carry out overall deep processing planning of betel nut; support betel nut deep processing plant in the main producing areas, establish betel nut initial processing and deep processing serial production line, and develop new betel nut product; build betel nut production, processing, transport and marketing information database and market information early warning mechanism, and improve betel nut processing information service platform to timely provide information services and continuously develop betel nut industry.
