Analysis of Renewal Strategies of Natural Rubber Plantations in Hainan Province
The renewal of natural rubber plantations is an important path to promote new varieties and new technologies of rubber trees,improve the production capacity,and ensure the sustainable development of the industry.Hainan Province is an important production base of natural rubber in China.Due to the slow renewal progress,the proportion of elderly and disabled rubber plantations is as high as 25.23％,which restricts the production capacity of natural rubber.The study analyzed the age structure and variety structure of rubber plantations in Hainan Province,which was verified through micro-survey data.The renewal scheme of rubber plantations in Hainan Province was set up under different renewal target scenarios.Through comparison,it was found that the feasible scenario was to update 14,000 hectares of rubber plantations annually from 2026 to 2035 to ensure that the proportion of elderly rubber plantations controlled within 15％ by 2035.Suggestions for the renewal of rubber plantations in Hainan Province have been put forward in terms of policy support,seeding supply,model promotion and technological innovation,in order to provide a reference for the safe and effective supply of natural rubber in China.
