Abstract: Based on the survey of rubber industry development in three major rubber planting provinces in China,Hainan,Yunnan and Guangdong,the effects of science and technology on promoting rubber tree cultivation and rubber plantation management were elucidated.Some problems in rubber tree cultivation and rubber plantation management were analyzed.Firstly,the administration and care during young rubber trees growth is not enough;secondly,research and utilization of rubber tree stock resources is not adequate;thirdly,the key techniques such as cold tolerance,drought resistance and wind resistance in rubber tree growth remain unsolved;fourthly,the soil fertility of rubber plantations is very low,and declines constantly.Moreover,the low renovation rate in low yield rubber plantation,improper composition of different age rubber trees,and weak study and application evaluation in social-economic-natural complex ecosystem of rubber forests existing in present rubber industry were also discussed.The suggestions were proposed as follows: improving overall production level of young rubber trees;accelerating the breeding of excellent rootstocks for rubber trees and developing cold tolerance,drought resistance,and wind resistance new rubber tree varieties;improving the rubber tree cultivation techniques with reduced weather damage such as wind prevention,cold tolerance and drought resistance;timely summarizing a set of high yield cultivation techniques in rubber trees;supplying enough fertilizers in rubber plantations and strengthening light fertilizer technology development;setting up and improving the periodical update rule of low yield rubber plantations;enhancing the research on rubber forest ecosystem’s function and application evaluation;Performing the technical regulations from Ministries of Agriculture effectively,which aimed at promoting the overall level of natural rubber industry in China.
