Background
The betel nut is the first of four southern medicines in China, is a tropical commercial crop with the second planting area and the first yield value in Hainan at present, relates to more than 70 and more than 200 thousands of farmers, accounts for 41 percent of agricultural population in the whole province, and accounts for 29 percent of the agricultural product sold by farmers in Hainan. The phenomenon of yellowing is the most troublesome problem in the process of planting and managing betel nuts, and the betel nut garden with the phenomenon of yellowing accounts for about one fourth of the conventional betel nut garden. The existing research shows that the areca etiolation phenomenon is more than 90 percent due to the fact that the fertilizer and water are not managed in place, and the etiolation disease caused by the phytoplasma infection is not more than 10 percent in a real sense. Investigation by the team finds that the yellowing of the leaves of areca catechu in Hainan mainly occurs in cold seasons and dry seasons, which indicates that the resistance of the areca catechu to low temperature and drought is poor, and reasonable fertilization is an important technical measure for improving the resistance of the areca catechu.
