海南岛位于热带的北缘,属热带季风气候区,光热水资源丰富,适宜多种南药生长发育。但是,由于海南岛各地气候条件差异较大,气候的地带性和非地带性特征很明显,所以,在不同地方的气候适应程度也不同。为了充分发挥海南气候资源的优势,发展南药生产,研究海南岛“四大南药”(槟榔、益智、壳砂、巴戟)的气候适应性与增产途径是很必 Hainan Island is located in the northern margin of the tropical, is a tropical monsoon climate zone, light and hot water is rich in resources, suitable for a variety of South medicine growth and development. However, due to the large differences in climate conditions across Hainan Island and the obvious zonal and non-zonal characteristics of the climate, the degree of climate adaptation in different places is also different. In order to give full play to the advantages of Hainan’s climatic resources and develop the production of southern medicine, it is very necessary to study the climate adaptability and yield-increasing ways of Hainan’s “four major southern medicines” (betel nut, puzzle, shell sand, and Morinda officinalis)
