The betel nut planting area and yield in Hainan have reached 94000 ha and 231000 t, respectively. There are some problems in betel nut planting such as dispersed cultivation, irrational planting layout, excessively dense planting and serious betel nut yellows. For the sustainable development of Hainan betel nut, it is necessary to focus on building the disease-resistant betel nut plantation, so as to prevent and control the occurrence and spread of betel nut yellows; transform the low-yield betel nut plantation, and strengthen betel nut production management, in order to improve betel nut yield and promote sustainable development of betel nut industry.
